In recent years，extreme temperature events occur frequently，and the drastic fluctuation of vegetable prices has a great impact on people’s production and life，through the study of the spillover effect of vegetable product prices under extreme temperature events，it can provide ideas for the government to better cope with the fluctuation of vegetable prices and maintain the market order．The daily price data of 21 kinds of vegetables in Shandong Province from 1 June 2017 to 30 June 2022 were selected to analyse the total spillover effect and individual spillover effect of the overall vegetable market on the basis of price yield by combining the spillover index method and the social network method，and the temperature data of the relevant period were also selected to explore the influence of extreme temperature on the price spillover effect of the vegetable market．From the overall perspective，the overall vegetable market price spillover effect is 53.73%；from the individual perspective，‘active’vegetables such as rape and Chinese cabbage have greater influence ithe vegetable market price spillover network；while‘independent’vegetables such as garlic and lotus root have less influence in the network．Vegetables such as garlic，lotus root and other‘independent’vegetables have less influence in the network．The impact of extreme temperatures on the overall vegetable market price spillovers is non-linear，with a greater impact on root and leafy vegetables．Based on this，it is proposed to monitor the prices of‘active’vegetables in the market and to strengthen the early warning of external shocks．

Based on the SPS（sanitary and phytosanitary）/TBT（technical barriers to trade）notifications for China’s vegetable exports from the WTO（World Trade Organization）statistics，this paper analyzes the general situation，types，and trends of TBT faced by China’s vegetable exports from 1996 to 2022．The research indicates that the TBT faced by China’s vegetable exports are characterized by a significant increase in the number of SPS/TBT notifications，with developed economies accounting for the majority of these notifications．The main types of TBT include commodity quarantine and inspection regulations，technical regulations and standards，and packaging and labeling requirements．The TBT faced by China’s vegetable exports show trends such as increasingly stringent technical standards，more involved stages，broader impact coverage，and more mandatory measures．Finally，this paper proposes policy recommendations，including
strengthening technological innovation and quality safety management across the entire industry chain，promoting mutual recognition of standards and active participation in international standard-setting，and enhancing market monitoring and responses to TBT．

In order to screen the suitable reference genes for the analysis of the relative expression level of anthocyanidin synthesis genes in different varieties and tissues of chili fruits，eight candidate internal reference
genes，namely，GAPDH，Actin，β-TUB，PP2A，UBQ2，DNA-J，ATPS，and ACBP，were selected for the analysis of the expression profiles of these targeted genes．They were examined in three fruit tissues（placenta，flesh，and seeds）from six pepper varieties，with three distinct fruit colors（yellow，red and green）using real-time fluorescence quantitative PCR（qRT-PCR）．The expression stability of the candidate internal reference genes was assessed using GeNorm，NormFinder，BestKeeper and RefFinder software．The results showed that glyceraldehyde-3-phosphate dehydrogenase（GAPDH）was the most suitable reference gene and ATP synthase（ATPS）was the least suitable reference gene in fruits of different varieties of Capsicum annuum．Using GAPDH as the reference gene，qRT-PCR analysis of key gnenes（chalcone synthase，CHS and chalcone isomerase，CHI）in anthocyanin biosynthesis pathway in different fruit tissues revealed significant expression variations among three pepper varieties with three different fruit colors，with expression trends consistent with transcriptome data．In contrast，using ATPS as the reference gene，the expression patterns of CHS and CHI deviated from the transcriptome data．The results showed that GAPDH was a stable gene in different fruit tissues of different varieties of chili peppers，and this study provides a valuable reference for the functional analysis of anthocyanidin synthesis-related genes and their regulatory mechanism in different fruit tissues across different varieties of chili peppers．

In this study，evaluated 29 inbred lines and 5 male sterile lines as experimental materials by inoculating them with six Chinese cabbage Plasmodiophora brassicae isolates collected from different regions in China：Xinmin（LNXM），Yutian（HBYT），Aba（SCAB），Baixiang（SDBX），Shenyang（LN01），and Yichang（HBYC）．Among the inbred lines，S13，S15，S16，and S24 demonstrated resistance to five P. brassicae isolates，while S17，S22，S23，S25，and S29 exhibited resistance to four isolates．Among the male sterile lines，M3 showed resistance against five isolates，whereas M1 and M4 were resistant to four isolates．Additionally，we screened the 29 inbred lines and 5 male sterile lines for the presence of seven clubroot resistance（CR）genes/loci（CRa，CRd，Crr1a，Crr3，CRk，CRc，and CRA3.7）．The results showed that among the inbred lines，S20 contained all seven resistance gene loci，while S18，S19，S25，S26，S28，and S29 each carried six of these loci．Among the male sterile lines，both M1 and M5 harbored four resistance gene loci.

Pumpkin（Cucurbita maxima）is one of the important vegetables with significant nutritional and economic values．To investigate the genetic diversity of commercial pumpkin varieties，we re-sequenced the genomes of 52 pumpkin germplasm materials using the next generation sequencing platform．The sequencing data were filtered and variation sites were identified，and then the phylogenetic analysis was performed．The results showed that 52 commercial pumpkin germplasm materials had abundant genetic diversity．Single nucleotide polymorphism（SNP）and insertion-deletion（InDel）loci had regional clustering tendencies with different distribution densities．The 52 pumpkin germplasm materials were divided into 7 groups by phylogenetic analysis，including 2，10，1，5，11，7 and 16 varieties，respectively．The first group contained two varieties of‘Jinli No.2’and‘Huobite’．The third group consisted of only‘Junrong’，which had great genetic differences with the other commercial varieties．These results provide substantial information for variety protection and breeding of pumpkins．

Ethylene response factor（ERF）is a pivotal transcription factor that modulates plant stress responses and anthocyanin biosynthesis．In this study，28 significantly differentially expressed ERF family members were identified using transcriptomic data from green and purple Dioscorea opposita plants exposed to saline-alkali stress．All these proteins harbor the conserved AP2 domain，characteristic WLG and YRG units，and a conserved tandem motif arrangement（motif 2-motif 3-motif 1）．Amino acid sequence analysis revealed that these ERF proteins consist of 143–327 amino acids，with molecular weights ranging from 15.9 to 35.3 kDa，and theoretical isoelectric points of 4.78-9.73；they are predominantly acidic and hydrophilic．All 28 ERFs proteins are localized in the nucleus，with 9 also showing cytoplasmic localization．Phylogenetic analysis indicated that these 28 ERFs proteins share high homology with known ERFs involved in anthocyanin biosynthesis in other species，implying their potential role in anthocyanin biosynthesis．In addition，their promoter sequences contain cis-acting elements responsive to light，hormones，environmental stress，and growth and development．The findings provide a foundation for further functional investigations into the role of ERF proteins in anthocyanin biosynthesis in D. opposita．

The length of epicotyl is one of the important characters that affect the appearance and taste quality of the pakchoi．In this study，short epicotyl material‘Qgc89A’and long epicotyl material‘Qgc102’were used as parents to construct F2 population，and computer vision software was used to design a set of accurately quantification scheme of epicotyl length of pakchoi．The QTL affecting the epicotyl length of pakchoi was identified on chromosome A02 by BSA-Seq．The KASP marker was developed in this QTL interval，and genotyping results showed that A02：3390650 was highly correlated with the epicotyl length of F2 population．The results of this study laid a good foundation for the fine mapping of genes regulating epicotyl length and molecular marker-assisted selection breeding．

Fresh-cut Artemisia selengensis holds significant potential in the ready-to-eat vegetable market owing to its high nutrition and desirable flavor．However，its high polyphenol content makes it highly susceptible to enzymatic browning after cutting，leading to substantial quality deterioration．So this study focuses on the phenolic compounds and enzymes involved in enzymatic browning of fresh-cut Artemisia selengensis．The composition and content of polyphenols were analyzed，and the activities of polyphenol oxidase（PPO），peroxidase（POD），and phenylalanine ammonia-lyase（PAL）during storage were determined using spectrophotometry．The enzymatic characteristics of PPO were studied，and an enzymatic kinetic equation was established．The interactions between predominant phenolic compounds and PPO in Artemisia selengensis was analyzed by molecular docking．The results revealed that fresh-cut Artemisia selengensis contains abundant types and contents of free phenols，with a free phenol content of 22.18 μg · g-1（FW），accounting for 61.8% of the total phenolic content．Browning was positively correlated with PPO activity in fresh cut Artemisia selengensis，and kinetics analysis showed that the Vmax of PPO was 16.50 × 10-8 mol · L-1 · s-1．As the key enzyme initiating enzymatic browning，PPO rapidly reacts with gallic acid，catechins，and chlorogenic acid in fresh-cut Artemisia selengensis．Molecular docking analysis showed that chlorogenic acid，gallic acid，epicatechin，and resveratrol form hydrogen bond networks with amino acid residues in the active cavity of PPO．The enzymatic reaction of phenolic substances in Artemisia selengensis catalyzed by PPO may be related to these hydrogen bond networks，thereby triggering enzymatic browning in fresh-cut Artemisia selengensis．

Black rot is the predominant bacterial disease affecting broccoli production．In this study，the black rot resistance of 62 cruciferous materials were assessed at the seedling stage using a spray inoculation method．Four materials highly resistant to Xanthomonas campestris pv. campestris race 3 were identified，including three broccoli varieties and one yellow rocketcress with disease indexes below 11.1．Conversely，four highly susceptible materials were also identified，including three broccoli and one cabbage，with disease indexes exceeding 80.00．The resistant materials screened in this study lay a foundation for subsequent breeding of black rot-resistant broccoli．

To explore the effects of melatonin（MT）priming on the emergence rate of cabbage seeds and the heat tolerance of seedlings，the open-field winter cabbage variety‘Zhonggan 1305’was treated with different concentrations of MT，which aimed to explore the effects of MT priming on the emergence rate of seeds，the morphological indicators（root length，fresh weight）and physiological characteristics（photosynthetic pigments，osmotic adjustment substances，membrane lipid peroxidation）under hightemperature stress（37 ℃）．The results showed that high-temperature stress at 37 ℃ significantly reduced the emergence rate of‘Zhonggan 1305’by 19.77%，compared with the temperature of 22 ℃．Treatment with 75 μmol · L-1 MT could effectively alleviate the inhibitory effect caused by the stress．Compared with the unprimed group，the emergence rate of‘Zhonggan 1305’seeds treated with 75 μmol · L-1 MT significantly increased by 13.22%，and the root length and fresh weight significantly increased by 25.40% and 18.59%，respectively．Physiological indices revealed that the contents of chlorophyll a，chlorophyll b，total chlorophyll content，andthe proline content in the seedling leaves significantly increased by 50.67%，83.04%，58.45%，and 105.35%，respectively，while the relative electrical conductivity and the malondialdehyde（MDA）content significantly
decreased by 42.60% and 33.78% respectively．In conclusion，MT priming alleviated the inhibitory effect of 37 ℃ high-temperature stress on the emergence of cabbage seeds and significantly enhanced seedlings heat tolerance by activating the antioxidant defense system and improving cell membrane stability.

Using the broccoli（Brassica oleracea L. var. italica Plenck）inbred line‘V04D0002’as experimental material，two WRKY53 homologous genes，BoWRKY53-1 and BoWRKY53-2，were cloned from seedling cDNA through PCR amplification．The coding sequences（CDS）of BoWRKY53-1 and BoWRKY53-2 are 948 and 966 bp in length，encoding 315 and 321 amino acids，respectively，with a protein sequence identity of 95%．Subcellular localization predictions indicate that both proteins are localized to the nucleus．Quantitative real-time PCR（qRT-PCR）analysis revealed that both genes are expressed in broccoli leaves，flowers，and florets，with significantly higher expression levels detected in florets．Furthermore，under low-temperature stress，BoWRKY53-2 exhibited significantly up-regulated expression at 3，6，and 9 hours after treatment compared to the control group，whereas BoWRKY53-1 showed a significant increase only at the 6-hour time point．These findings suggest that both BoWRKY53-1 and BoWRKY53-2 respond to cold stress and may play roles in the plant’s adaptation to low-temperature environments．

Using green petiole non-heading cabbage as the experimental material，this study employed
the nutrient film technique（NFT）to examine the effects of different liquid level height，supply frequencies，
and flow rates on the growth and quality of pakchoi．The results indicated that plant growth，photosynthetic
performance and quality indices exhibiting an increasing trend as the liquid level height rose from 0.5-2.0 cm，
with no significant differences observed between 2.0 cm and 4.0 cm．Under nutrient supply intervals of 20-
60 min，no significant differences were detected in aboveground fresh weight，dry weight，photosynthesis，or
related indices．However，extending the supply intervals to 80 min significantly reduced plant growth and
photosynthetic efficiency，while the overall quality of the non-heading cabbage showed a declining trend
with prolonged supply intervals. The nutrient solution（0.5-4 L · min-1）showed no significant effects on the
growth，photosynthetic performance and quality of pakchoi．Considering the growth，photosynthesis and quality
indices comprehensively，the optimal conditions for hydroponic production of pakchoi were a liquid level height
of 2.0 cm，a supply interval of 60 min with a 5 min delivery period，and a flow rate of 0.5 L · min-1．This
study identified key optimal parameters for the hydroponic production of pakchoi，including appropriate liquid
level height，supply frequency，and flow rate，providing a theoretical foundation and technical reference for
improving the yield and quality of pakchoi and other leafy vegetables under NFT hydroponic systems．

In response to the problems of extensive management and low water-fertilizer use efficiency in Pugionium cornutum production，this study explores the effects of water-nitrogen coupling on the growth，
development，and yield of Pugionium cornutum．Based on a pot experiment，a two-factor（irrigation amount
and nitrogen application rate）experimental design was adopted．The irrigation water was set at three levels：
severe deficit irrigation W1（30%-40% of field water holding capacity），deficit irrigation W2（50%-60% of
field water holding capacity），and sufficient irrigation W3（70%-80% of field water holding capacity）．The
nitrogen application rates were set at four levels：no nitrogen application N0（0），low nitrogen N1（135.0 kg ·
hm-2），medium nitrogen N2（292.5 kg · hm-2），and high nitrogen N3（450.0 kg · hm-2），with 12 treatment combinations established．The results showed that compared with the nitrogen-free treatment，water-nitrogen
coupling had a significant effect on promoting the growth and development of Pugionium cornutum．The plant
height，spread and leaf area of W2N2 were significantly increased，the plant height and spread of W3N2 were
significantly increased，and the leaf area of W3N3 was significantly increased，with certain differences between
different treatments．Yield was significantly improved，with the W2N2 treatment achieving the highest yield
of 6 529 kg · hm-2，which was 94.37% higher than the treatment with the lowest yield（W1N1）．The W2N2
treatment exhibited the highest water use efficiency at 1.31 kg · m-3．Principal component analysis results
indicated that the W2N2 treatment achieved the highest comprehensive score．In conclusion，when the field
water holding capacity is 50%-60% and the nitrogen application rate is 292.5 kg · hm-2，the comprehensive
yield of Pugionium cornutum is the highest. The research results can provide certain theoretical basis and
technical support for field production of Pugionium cornutum．

In order to standardize the cultivation of head lettuce in the Beijing area，we studied the effects
of different planting densities on the growth，yield，quality，and planting benefits of the‘Radar’in the
spring crop of plastic greenhouses．The results showed that the plant height and width of head lettuce during
the rosette stage were not significantly affected by the planting density．During the harvest period，the mass
of leaf balls and the net vegetable yield per unit area showed a trend of first increasing and then decreasing
with the increase of density，then the content of VC，the aboveground biomass per unit area，the number of
commercial vegetables，output value，and profit all showed an increasing trend with the increase of density．
When the planting density reaches 94 500 plants per hectare，the VC content，aboveground biomass per unit
area，the number of commercial vegetables，output value and profit of head lettuce are the highest．Therefore，
it is recommended that the planting density of head lettuce for the spring crop in plastic greenhouses be 94 500
plants per hectare to achieve higher planting benefits.

In order to thoroughly investigate the characteristics and disparities in nutritional quality as
well as inorganic element accumulation between wild and artificial morel mushrooms sourced from Daozhen
and Shuicheng origins in Guizhou，this study meticulously analyzed the contents of five key nutritional
components，namely total phenols，total flavonoids，total saponins，total polysaccharides，and proteins，
along with 22 inorganic elements in both the caps and stalks of morel mushrooms from diverse origins of
wild and artificial varieties. Comprehensive assessments were carried out through correlation analysis，PCA （principal component analysis），and the evaluation of nutritional indices. The results indicated that significant
differences existed in the contents of total phenols，total flavonoids，total saponins，total polysaccharides，
and proteins between the wild and artificial morel mushrooms from the two origins. Notably，most nutritional
indexes demonstrated a trend where the values in the caps were higher than those in the stalks. Specifically，the
protein content in morel mushrooms was 2.13 to 5.78 times that of five common vegetables. Regarding inorganic
elements，the contents of Pb，Hg，Al，Cu，Fe，Zn，and Mn in wild morel mushrooms were higher than
those in artificial ones. In terms of the distribution within the mushroom，the contents of As，Hg，Se，Cu，
Zn，Mn，Sr，Ca，P，and K in the caps were higher than those in the stalks，while the situation was reversed
for Al．Moreover，the Na contents of morel mushrooms from both locations were substantially lower than
the national average，whereas the opposite was true for Se and K．The PCA analysis results and mineral
element nutritional quality index（INQ）values showed the same pattern across the two origins，with Daozhen
being higher than Shuicheng．In conclusion，both the stalks and caps of morel mushrooms can serve as highquality
protein sources. Given their potassium-rich and sodium-poor characteristics，they are suitable as dietary
supplements for hypertensive patients．
