    Abstract:As a major protected vegetable production hub in Shandong Province,Zibo City plays a vital role in ensuring food supply,increasing farmers’incomes,and promoting rural revitalization.However, following 40 years of development,Zibo’s protected agriculture industry faces critical challenges,including aging greenhouse structures,an aging workforce,and obsolete technologies,which significantly impede the high-quality development of the local sector.Based on field surveys and data analysis,this study systematically investigates the current status of aging greenhouse facilities and identifies four innovative organizational renovation models:Party branch-led,private investment-driven,cooperative-led,and farmer-initiated models. Additionally,four technical upgrading strategies are proposed:consolidating small greenhouses into larger structures,reinforcing wall thickness,expanding structural dimensions(height and width),and integrating smart technologies.This study further evaluates the suitability of these renovation models in relation to the specific facility conditions across various districts and counties.Practical applications demonstrate that the upgraded facilities exhibit significant improvements in structural stability,disaster resilience,microclimate regulation,crop yields,and overall economic benefits.Accordingly,policy recommendations are proposed in three key areas:intensive land use,standardized smart transformation,and the optimization of external support systems.This study provides practical insights and a reference framework for the modernization of protected agriculture in similar northern regions of China.

    Abstract:Eggplant is an important solanaceous fruit vegetable in China,characterized by extensive cultivation coverage and high yield,with its planting area ranking fifth among all domestic cultivated vegetables.Diversified consumption patterns of eggplant have been developed across China,and distinctive habitual consumption preferences have taken shape in different geographical regions.Combined with years of practical experience in eggplant seed marketing and variety breeding,this paper systematically summarizes the core characteristics,market demands,cultivation patterns,geographical distribution and variety requirements of major commercial eggplant types in China from the perspective of market consumption. The cultivated areas of different eggplant types are also estimated based on seed consumption volume.The results reveal that commercial eggplant cultivars in China are categorized into nine mainstream consumption groups plus a set of specialty eggplant ecotypes.Targeted elite cultivars such as firm-fleshed long purple eggplant and amaranthred long eggplant have been bred to adapt to varied production systems including greenhouse,arch shed and open-field cultivation in line with regional consumption preferences and local agroclimatic conditions.Current eggplant breeding is evolving toward three orientations:dedicated cultivars for barbecue processing,varieties compatible with prefabricated vegetable processing,and genotypes with enhanced stress tolerance.Eggplant production exhibits prominent regional agglom eration,with large-scale production bases covering over ten thousand mu emerging in Shouguang,Emei and other key production zones.Differentiated regional planting
    layout has been established for distinct cultivars,and the national total cultivation area exceeds ten million mu,which guarantees stable domestic market supply of eggplant.

    Abstract:With the acceleration of industrialization,soil heavy metal pollution(such as Cd,Pb,Cu,and Zn)becomes increasingly serious. The problem of excessive heavy metals in global farmland soil affects 14%-17% of agricultural areas.As an important global economic crop,tomatoes are vulnerable to soil heavy metal pollution in terms of growth and quality,threatening the sustainable development of the tomato industry.Soil heavy metal stress inhibits tomato seed germination and seedling growth,resulting in photosynthetic damage and metabolic disorders.Tomatoes defend themselves by activating the antioxidant system and the regulation mechanism of mineral elements.This article systematically reviews the physiological and biochemical response mechanisms of tomatoes under soil heavy metal stress,and points out that current research has limitations such as unclear complex pollution mechanisms and insufficient molecular network analysis. In the future,it is necessary to combine multi-omics technology,CRISPR-Cas9 gene editing,and plant-microbial combined remediation strategies,in order to provide theoretical support for the safe production of tomatoes in areas contaminated by heavy metals and the sustainable development of the tomato industry.

    Abstract:Faced with the annual generation of over 100 million tons of vegetable residues,resolving the paradox of transforming these materials from an environmental burden into value-added resources has become critical for advancing green and sustainable agricultural development in China.This study provides a systematic assessment of six major valorization pathways for vegetable residues,including fertilizer,feed,substrate, energy,food,and material applications,and highlights the inherent cost-efficiency trade-offs behind their technological diversification.Low-value pathways such as direct field return,constrained by the inherently low carbon-to-nitrogen(C/N)ratio of vegetable residues,are associated with elevated risks of nitrogen loss and greenhouse gas emissions,whereas high-value pathways,including food-and material-oriented utilization,remain limited by technical complexity and economic feasibility.Further analysis indicates that this dilemma fundamentally arises from two structural contradictions:the mismatch between the temporalspatial concentration of residue generation and the dispersed distribution of utilization demand,and the tension between high technical requirements and strong cost constraints.Looking forward,the establishment of a regionally adaptive system integrating decentralized preprocessing with centralized resource utilization,together with enhanced cross-sectoral technological integration,is essential to enable coordinated improvements in environmental performance and economic viability.

    Abstract:Based on transcriptome differential expression analysis between the cucumber(Cucumis sativus L.)small-leaf mutant cpa1 and wild type(WT),we found that the expression of the MADS-box transcription factor gene CsAGL62b(CsaV3_3G045410)was significantly downregulated in the cpa1 mutant. The target gene of the cpa1 mutant has been identified as CsHLS1,and its homologous proteins have been shown to play vital regulatory roles in apical hook development and abiotic stress responses in plants.To further dissect the function of CsAGL62b ,the full-length coding sequence of CsAGL62b was cloned from wild-type cucumber using RT-PCR.Bioinformatic analysis showed that this gene encodes a protein of 225 amino acids containing a typical MADS domain.Phylogenetic analysis revealed that it has the closest genetic relationship with CmAGL62b from melon.Promoter cis-element prediction identified regulatory elements associated with light signaling and multiple plant hormones,including methyl jasmonate(MeJA),gibberellin(GA),and salicylic acid.Gene expression pattern analysis indicated that CsAGL62b showed the highest expression level in roots,followed by lateral buds and leaves.Moreover,its transcript abundance was significantly higher in weak roots than in other root types.In the root maturation zone,CsAGL62b  expression was significantly induced and upregulated by exogenous GA and abscisic acid(ABA).Meanwhile,CsAGL62b in seedling
    leaves responded rapidly to ABA and was upregulated,reaching its peak expression at 6 h of ABA treatment.Stress assays demonstrated that the expression of CsAGL62b exhibited a trend of initial increase followed by decrease under drought,salt,and high-temperature stresses.In contrast,its expression was significantly downregulated under low-temperature stress,suggesting that CsAGL62b  may participate in multiple abiotic stress responses in cucumber.In summary,this study systematically characterized the molecular features of the cucumber CsAGL62b gene for the first time,and provides a solid molecular foundation for further elucidating its biological functions in root growth,development,and stress resistance in cucumber.

    Abstract:Clubroot disease in cruciferous crops severely limits the yield and quality of cabbage.Given the scarcity of clubroot-resistant germplasm in cabbage and the abundance of resistant resources in Chinese cabbage,cabbage line‘337’was used as the female parent and Chinese cabbage line‘19S4’,which carries multiple resistance genes,as the male parent for distant hybridization.Embryo rescue was employed to overcome reproductive isolation.Together with marker-assisted selection,morphological observation,ploidy determination,pollen viability testing,and artificial inoculation with multiple clubroot isolates at the seedling stage,a new cabbage germplasm pyramiding multiple resistance genes was developed.The results showed that distant hybridization combined with embryo rescue successfully introduced multiple resistance genes from Chinese cabbage into the cabbage genetic background.The progeny exhibited excellent resistance to clubroot isolates from different sources,and their resistance was significantly superior to that of single-resistant materials containing only CRa,showing broad-spectrum and durable resistance.After colchicine-induced chromosome doubling,fertility of the interspecific hybrid(F1)was effectively restored,with plump pollen grains and viability approaching 100%.These findings provide important genetic materials and technical support for breeding clubroot-resistant cruciferous vegetables.

    Abstract:Gummy stem blight(GSB)is a widespread fungal disease in cucumber crops.It mainly attacks the stems,leading to stem wilting,leaf yellowing,and delayed fruit development.This ultimately impacts yield and fruit quality.Currently,there is limited knowledge about the genetic basis of GSB resistance in cucumbers,with existing research primarily focused on wild cucumber species,which hinders the progress of molecular breeding efforts.To address this,we created a population(F2 generation)by crossing a gummy stem blight-resistant cucumber line‘CSIVF0086’with a gummy stem blight-susceptible one‘CSIVF0155’, and tested the disease resistance of 200 plants each in two separate growing seasons(Spring 2024 and Spring 2025).Our analysis showed that resistance in seedlings is a quantitative trait.We then constructed two genetic maps using these 400 plants together with 84 genetic markers(InDel markers).The total lengths of the two seasonal genetic maps were 677.5 and 706.2 cM,with average marker distances of 9.41 and 10.54 cM, respectively.Based on the phenotypic and genotypic data,QTL mapping results indicated that a novel QTL, designated as Qgsb3.1,was consistently detected on chromosome 3 across both experimental seasons.Its flanking markers are InDel3-2 and InDel3-4,with LOD values of 3.24 and 4.20,and phenotypic contribution rates of 14.5% and 19.0%,respectively.These findings provide an important basis for the fine mapping of cucumber gummy stem blight resistance genes and molecular marker-assisted selection breeding.

    Abstract:Leaf curling is a common phenotypic variation in plant leaves,which has attracted extensive attention due to its impact on photosynthetic efficiency and crop yield.In this study,the pepper advanced inbred line 6421 and its stably inherited inward leaf-curling mutant CL1,which was isolated from the ethyl methane sulfonate(EMS)-mutagenized 6421 population,were used as materials to systematically analyze leaf developmental dynamics cytological characteristics and genetic inheritance patterns.The results showed that the wild-type 6421 exhibited flat leaves throughout the entire growth period,whereas the mutant CL1 maintained flat leaves only at the seedling stage.From the flowering stage,the leaves of CL1 gradually curled inward,reaching the peak curling at the green fruit stage.Morover,from the flowering to the red fruit stage, the daily growth rates of leaf width and leaf area of CL1 were significantly lower than those of 6421.During the flowering to green fruit stage,the contents of chlorophyll a,totaland carotenoids in leaves of CL1 leaves were significantly lower than those in 6421.By the red fruit stage,only contents of chlorophyll a and total chlorophyll in CL1 leaves remained lower compared to 6421.Histological analysis revealed that the crosssection of the CL1 leaf exhibited significant inward curling.The palisade and spongy tissue in the leaves of CL1 were disordered arranged,with reduced intercellular spaces,and the boundary between them were blurred or even fused.Moreover,the number of cell layers and cells in the vascular tissue of CL1 was less than that of 6421.Genetic analysis confirmed that the leaf-curling trait in pepper was controlled by a single recessive
    gene.These results provide an important basis for further elucidating the molecular mechanism underlying leaf development in pepper.

    Abstract:To clarify the growth-promoting and disease-control effects of a novel composite microbial agent‘ Zhongke 303’on potato in Inner Mongolia,this study systematically evaluated the agent and its six constituent biocontrol strains(Bacillus thuringiensis NMB1,B. amyloliquefaciens NMB3,B. megaterium NMB4,Acinetobacter oleivorans NMB17,Burkholderia pyrrocinia XXB-24,and Pseudomonas fluorescens pf27)for plant-growth promotion and control of five soil-borne potato diseases,using physiological assays, plate confrontation tests,pot experiments,and field trials.Growth-promotion tests demonstrated that all six biocontrol strains and the composite agent possess nitrogen-fixing capabilities and produce indole-3-acetic acid (IAA).Strains NMB4,NMB17,XXB-24,pf27,and the composite agent also exhibited the ability to solubilize phosphorus and release potassium.Pot and field experiments further confirmed that these biocontrol bacteria significantly increased plant height,above-ground fresh weight,above-ground dry weight,and tuber weight.Plate confrontation assays revealed that the composite agent inhibited the pathogens responsible for Fusarium wilt,Verticillium wilt,black scurf,and common scab,with inhibition rates ranging from 11.09% to 33.04%,outperforming most individual strains.In pot experiments,the composite agent demonstrated control effects of 50.01%,58.73%,68.58%,and 75.25% against these four diseases,respectively.Field trials conducted at two test plots showed no significant difference in disease control between seed dressing alone and seed dressing combined with drip irrigation for common scab,black scurf,and powdery scab.Notably,seed dressing alone achieved better control outcomes.In summary,the composite microbial agent‘Zhongke 303’exerts significantly stronger growth-promoting and disease-suppressing effects than any single strain, offering reliable technical support for the sustainable and efficient management of soil-borne diseases in major potato-growing regions.

    Abstract:This study evaluated five planting methods to optimize potato production for chip processing,especially for market availability window from January to March in Yunnan Province.The potato processing variety‘Yunshu 304’was tested at two altitudes:Dongchuan Dazhai(about 1 200 m)and Dongchuan Lümao (about 1 500 m).The experiment followed randomized complete block design with three repeats,comparing whole seed tuber and seed pieces under plastic mulch,straw mulch and open field conditions.Seed pieces in open field served as control(CK).The results showed that,compared with the control(CK),the whole seed tuber with plastic mulch significantly improved the emergence rate(8.42 percentage points),plant height (24.24%),stem diameter(21.98%),and tuber number by 50.36%,resulting in a 26.48% higher yield.Interestingly,this treatment demonstrated no significant effects on the tuber shape,starch content,dry matter content,reducing sugar content,flesh color,and potato chips color,thereby ensuring the processing quality of potatoes.Altitude significantly influenced plant height(P < 0.01)and leaf count(P < 0.01).But no significant yield differences were observed across altitudinal variations.The tubers produced in Dazhai exhibited more regular,rounder,smooth shape slightly yellower flesh compared with that of Lümao.Moreover,the starch content and dry matter content of the tubers in Dazhai were significantly higher than those of tubers in Lümao by 3.06 percentage points and 3.10 percentage points,respectively,while the reducing sugar content was significantly lower than that of tubers in Lümao.Notably,the reducing sugar content in both sites was lower than the acceptable threshold(0.33%)of reducing sugar for potato chips processing,the color of potato chips is not affected by site.There was a significant interaction between treatments and sites on the number of stems(P < 0.05)and stem diameter(P < 0.01),while other traits showed no significant interaction effects (P > 0.05).Overall,the whole seed tuber with plastic mulch is recommended an optimal strategy for cultivation of autumn potato in Yunnan,ensuring both higher yield and suitable processing quality.

    Abstract:To explore the effects of Azotobacter chroococcum on rhizosphere microbial community structure,bulb metabolite composition and vitamin C synthesis of Lilium davidii var. unicolor,peat mixed with perlite was set as the control(CK),and peat + perlite supplemented with A. chroococcum served as the treatment(T)with the inoculant concentration of 1 × 108 cfu · mL-1.The rhizosphere soil physicochemical properties and microbial diversity as well as bulb metabolome were determined to analyze the effects of A. chroococcum on rhizosphere microenvironment,microbial community function and vitamin C accumulation in bulbs of substrate-cultured Lilium davidii var. unicolor.The results showed that inoculation with A. chroococcum effectively improved rhizosphere soil nutrient status;the contents of available potassium and available phosphorus in T treatment were 1.41 times(P < 0.001)and 1.93 times(P < 0.01)those in CK,respectively,while soil pH slightly decreased compared with CK.In terms of soil bacterial diversity,at the phylum level,the relative abundances of Proteobacteria and Bacteroidetes in T treatment increased by 3.49 and 2.41 percentage points compared with CK.At the genus level,the relative abundances of Granulicella,
    Streptomyces and Rhodobacter increased obviously;the relative abundance of Haliangium decreased by 3.08
    percentage points,and that of IMCC26256 also declined markedly.No significant differences were observed in the relative abundances of Ochrobactrum and Devosia between treatments.The vitamin C content of lily bulbs in T reached 20.25 mg · g-1,which was significantly increased by 39.23% compared with CK(P <0.05).A total of 450 differential metabolites were screened between T treatment and CK,which were mainly enriched in 14 key pathways,including phenylpropanoid biosynthesis,amino acid metabolism,linoleic acid metabolism,and the ABC transporter pathway.Correlation analysis indicated that the relative abundance of dominant rhizosphere microflora was positively correlated with the content of key metabolites for bulb vitamin C synthesis.Specifically,Granulicella abundance was positively correlated with L-arginine,and Rhodobacter abundance was positively correlated with L-2-amino-4-methylene glutaric acid.Moreover,L-arginine content was positively correlated with total salt and available potassium that regulate the distribution of dominant microflora.In conclusion,A. chroococcum probably promotes the biosynthesis and accumulation of vitamin C in Lilium davidii var. unicolor bulbs synergistically by reshaping rhizosphere microbial community structure and activating related metabolic pathways.This study provides a reference for the application of microbial inoculants in green cultivation and quality improvement of Lilium davidii var. unicolor

    Abstract:With the aim of screening for tomato germplasm resources resistant to Tuta absoluta,this study utilized 34 tomato accessions and conducted natural infestation with Tuta absoluta adults in a solar greenhouse, at 30 days after inoculation,the number of leaf mines per 100 leaves,fruit infestation rate,and pest index

    were systematically investigated.The resistance levels of different tomato germplasm resources to Tuta absoluta were comprehensively evaluated based on the membership function method and cluster analysis.The results showed that none of the tested tomato germplasm resources were completely immune to Tuta absoluta,but significant differences in resistance were observed among the different resources.Among them,the number of mines per 100 leaves of Z2401 and Z2402 was less than 10.00,and both the fruit boring rate and pest index were less than 3.00%.They ranked first and second in the total ranking of membership functions,indicating the strongest insect-resistance.Followed by Z2403,Fanghua 609,Z2405,Z2407 and Z2406,the number of mines per 100 leaves and leaf damage rate were between 10.00-20.00,the fruit infestation rate and pest index ranged

    from 5.00% to 13.00% and from 5.00% to 11.00%,respectively,and they ranked third,fourth,fifth,sixth
    and seventh in the total ranking of membership functions,showing medium resistance.For Z2429,Z2430,
    Z2431,Z2432,Z2433 and Z2434,the number of mines per 100 leaves was greater than 55.00,and both the
    fruit boring rate and pest index were greater than 25.00%.They ranked 28th,32nd,30th,31st,33rd and 34th
    in the total ranking of membership functions respectively,being highly susceptible tomato germplasm resources,
    which should be recommended to avoid its use during the breeding of insect-resistant tomato resources.The
    results of cluster analysis further supported the above resistance classification,and the findings can provide a
    reliable basis for the precise screening of tomato germplasm resistant to Tuta absoluta.

    Abstract:The experiment evaluated the effects of A-frame,arch-shaped,and fence trellis systems on the growth,yield,and fruit quality of cherry tomatoes(Solanum lycopersicu var. cerasiforme),aiming to identify an optimal trellising method for open-field overwintering cultivation in western Guangdong Province. The results showed that plants grown on the fence trellis exhibited significantly lower plant height compared to those on the arch-shaped and A-frame trellises.However,the fence trellis promoted greater canopy spread and improved light transmittance within the canopy.No significant differences were observed in fruit transverse diameter,longitudinal diameter,fruit shape index,peel color among the trellis types.Nevertheless,the A-frame trellis resulted in higher rates of malformed fruit and fruit cracking compared to the arch-shaped and fence trellises.The contents of soluble protein,total flavonoids,lycopene,and the sugar–acid ratio in cherry tomatoes grown on fence trellis systems increased by 13.33%,22.22%,13.49%,and 14.25%,respectively, compared with those on A-frame trellis.Additionally,the reducing sugar content was 0.29 percentage points higher,while the titratable acid content decreased by 0.04 percentage points.The yield under the A-frame trellis was 1 715.52 kg per 667 m2,while compared to this,the fence and arch-shaped trellises increased yield by 15.47% and 10.58%,respectively.Furthermore,the disease index for late blight(Phytophthora infestans),and the population densities of whiteflies(Bemisia tabaci)and leafminers(Liriomyza spp.) were lower on the arch-shaped and fence trellises than on the A-frame trellis.The late blight disease index of the A-frame plants was 184.62% and 122.00% higher than that of the arch-shaped and fence trellis plants,respectively;the number of leafminers in the upper canopy of the A-frame plants was 120.00% and 266.67% higher than that of the arch-shaped and fence trellis plants,respectively;and the number of whiteflies in the lower canopy of the A-frame plants was 103.37% and 112.95% higher than that of the arch-shaped and fence trellis plants,respectively.In conclusion,the fence trellis system resulted in the most significant benefits for enhanced cherry tomato yield and fruit quality,and simultaneously reducing pest and disease incidence and increasing economic returns,demonstrating promising application value for widespread adoption.

    Abstract:The north one-season potato production region is an important seed potato and commercial potato production area in China,which is highly threatened by potato virus diseases(especially PVY,PVX and PVA).In order to identify elite germplasm identification with multiple virus resistance and excellent agronomic traits suitable for this region,11‘Longshu’cultivars were evaluated using a completely randomized block design in this study.Mechanical inoculation with PVY,PVX,and PVA viruses was conducted to systematically determine the disease index of each cultivar.Tuber yield and starch content were measured,followed by resistance classification,trait correlation analysis,and comprehensive evaluation using the membership function method.The results showed that PVY resistance varied significantly(disease index 1.65-84.58),with outstanding differentiation among cultivars,among which‘Longshu 24’was highly susceptible;PVX and PVA resistance were generally excellent,but‘Longshu 28’exhibits relatively low resistance to PVX.The variation in yield and starch content of the cultivars rather narrow,among which
    the yields of‘Longshu 32’and‘Longshu 31’exceeded 45 t · hm-2,and the starch content of‘Longshu 33’was as high as 18.20%.Further analysis of trait correlation showed that starch content was significantly negatively correlated with PVX disease index,and yield was significantly positively correlated with PVA disease index.Through comprehensive evaluation by the membership function method,‘Longshu 33’was identified as the optimal germplasm.This variety not only exhibits high comprehensive resistance to viral diseases but also possesses high starch content and demonstrates a certain yield potential(approximately 41 t · hm-2).The‘Longshu 33’identified in this study can be used as an ideal material for analyzing the synergistic mechanism of multiple traits,and initially analyzed the synergistic and balance relationship of‘resistance-yieldquality’in the‘Longshu’cultivars.Which provides a key germplasm and theoretical basis for high-yield and high-quality breeding for virus disease resistance in the north one-season potato production region.It provides key germplasm and theoretical basis for breeding high yield and high quality of virus disease resistance in the north one-season potato production region.

    Abstract:The toxicity activity and field control efficacy of six different types of insecticides against cabbage aphids in Tai’an,Shandong Province,were determined using the leaf-dip method and field efficacy trial method.Laboratory toxicity results showed that Lipaphis erysimi exhibited the highest sensitivity to cyantraniliprole,with an LC50 of 3.02 mg · L-1,while Myzus persicae was most sensitive to sulfoxaflor,with an LC50 of 6.97 mg · L-1.There were certain differences in susceptibility between the two aphid species to the same insecticide;L. erysimi showed higher sensitivity to all six insecticides than M. persicae,with toxicity ratios ranging from 1.46 to 7.41-fold.The field efficacy trial results indicated significant differences in the control effects of the six insecticides against cabbage aphids.One day after treatment,the 22% sulfoxaflor SC at 24.75 g · hm-2 and 41.25 g · hm-2 achieved higher control efficacies of 87.54% and 89.06%,respectively, which were extremely significantly higher than those of the other insecticide treatments.Three days after treatment,the control efficacy of all insecticide treatments increased compared to that at 1 day,except for the 25 g · L-1 deltamethrin EC at 3.75 g · hm-2 and 7.50 g · hm-2.Among them,the 50% flonicamid WDG at 60.00 g · hm-2 and 75.00 g · hm-2,22% sulfoxaflor SC at 24.75 g · hm-2 and 41.25 g · hm-2,and 10% cyantraniliprole OD at 60.00 g · hm-2 achieved control efficacies of 93.09%,94.97%,91.80%,93.57%,and 91.10%,respectively,which were extremely significantly higher than those of the other treatments.Seven days after
    treatment,the control efficacies of 50% flonicamid WDG at 60.00 g · hm-2 and 75.00 g · hm-2,22% sulfoxaflor SC at 24.75 g · hm-2 and 41.25 g · hm-2,and 10% cyantraniliprole OD at 45.00 g · hm-2 and 60.00 g · hm-2 remained stable above 90%,with the highest reaching 96.94%,demonstrating excellent control effects.In summary,50% flonicamid WDG,22% sulfoxaflor SC,and 10% cyantraniliprole SC can be recommended as the preferred insecticides for controlling cabbage aphids in Tai’an.In field control,the appropriate insecticide should be selected based on the species composition and proportion of aphids,applied in rotation,the number of applications and pre-harvest interval should be strictly controlled.

    Abstract:Cardamine violifolia O. E. Schulz is a Brassicaceae plant with significant ecological functions and potential economic value.However,its low and uneven seed germination restricts the utilization of its resources.To determine the optimal seed-soaking conditions and analyze their effects on germination characteristics,treatments including warm water soaking(20,23,25,27,30 ℃),gibberellin soaking(0,10,50,100,150,200 mg · L-1),and selenium soaking(0,10,40,80,160 mg · L-1)were established.The germination rate,germination energy,and germination index were subsequently measured. The results showed that the optimal temperature for warm water soaking was 25 ℃,yielding a germination rate of 88.75%,germination energy of 67.25%,and a germination index of 83.31%;both excessively high and low temperatures adversely affected seed germination.The optimal concentration for gibberellin soaking was 50 mg · L-1,resulting in a germination rate of 90.00%,germination energy of 70.33%,and a germination index of 81.93%,whereas higher concentrations(150 mg · L-1 and 200 mg · L-1)inhibited seed germination. Selenium soaking exhibited no inhibition at lower concentrations but demonstrated a pronounced inhibitory effect at higher concentrations,particularly at 160 mg · L-1.These findings provide technical support for the artificial breeding and resource development of C. violifolia
