    China is the world’s largest producer of vegetables,with vegetables being the primary export category of Chinese agricultural products,accounting for 16.157% of agricultural exports in 2022.In the context of the RCEP agreement’s signing and implementation,it is highly significant to explore the status and potential of China’s vegetable trade with its partners to deepen the positive eff ects of exports and enhance the international competitiveness of Chinese vegetables.The study utilizes panel data of China’s vegetable export trade to RCEP partners from 2006 to 2022,constructs a stochastic frontier gravity model and a trade inefficiency model,empirically analyzes China’s trade efficiency and its influencing factors with respect to RCEP partners,and measures the export potential of each country.The results indicate that the economic level,population size,economic disparity,vegetable yields,and trade environment of China and RCEP partners significantly impact vegetable exports.The rule of law,economic institutional environment,and infrastructure level of RCEP partners positively infl uence the effi ciency of vegetable exports.However,the level of integrity in export destinations and improvements in government effi ciency,conversely,negatively aff ect trade effi ciency.The average effi ciency of China’s vegetable exports to RCEP partners over the years is 0.667,though there are signifi cant diff erences among the countries within the RCEP partnership.China should continue to enhance the quality of its vegetable exports,expedite the implementation of the RCEP agreement,and further expand the depth and breadth of its cooperation with RCEP partners to reduce trade resistance and promote the continued growth of vegetable export volumes.

    Abstract:In 2024,the general market prices of vegetables predominantly adhered to the typical pattern of annual seasonal fluctuations.Nevertheless,during the summer-autumn periods,the prices tended to operate at relatively elevated levels.Owing to the impact of unfavorable weather conditions and their sustained eff ects,it is anticipated that the upward trajectory of vegetable prices in the current winter and the forthcoming spring will be less steep compared to previous years,with a potentially longer duration of the price-increasing cycle.Taking into account the fact that the overall vegetable prices were on the higher side in 2024 and the acreage under cultivation has increased year-on-year,it is projected that the overall supply of vegetables in the spring of 2025 will be ensured.

    Taking the new variety of‘eggplant 1055’ as test material,this paper explored the effects of paclobutrazol spraying concentrations and times of application on eggplant plant height,internode length and fruit characters under different cultivation modes.In spring at open fields,this experiment set up 6 spray concentrations(0 as CK,25,50,100,200,300 mg·L-1)and one spray frequency(3 times)altogether 6 treatments. In autumn at solar greenhouse,5 spray concentrations(0 as CK,25,50,100,150 mg·L-1)and 3 spray frequency(1,2,3 times)were set altogether 11 treatments. The results showed that under different environments paclobutrazol could all hold up the growth of eggplant plant.Along with the increase of paclobutrazol concentration and number of application times,plant height and internode length would gradually decrease. At the same time,paclobutrazol spraying would affect the development of eggplant fruit,increase fruit transverse diameter and decrease fruit longitudinal diameter. Along with time extension after spraying,the effect of paclobutrazol would gradually weaken. Comprehensive analysis about effects of paclobutrazol on eggplant plant architecture and fruit characters showed that 15 days after field planting,spraying paclobutrazol 50 mg·L-1 3 times in open field cultivation in spring,and spraying 25 mg · L-1 3 times in solar greenhouse cultivation in autumn with 7 days interval could effectively reduce eggplant plant height and internode length,maintain its fine fruit type and increase its single fruit weight.

    In order to clarify the genetic rule of peduncle length of tomato,the four generation populations of P1,P2,F1 and F2 were established from the cultivated variety ‘Ailsa Craig’(AC)with short peduncle length and Solanum lycopersicoides LA1964 with long peduncle length.The major genes and multiple genes mixed genetic model were used to estimate the genetic parameters of tomato peduncle length of the second,third and fourth inflorescences.The results showed that the total peduncle length,anterior peduncle length and posterior peduncle length of the second and third inflorescences were consistent with the MX2-ADI-AD model.But the optimal genetic model for the fourth inflorescence length of total peduncle,anterior peduncle and posterior peduncle was the model of MX2-ADI-ADI.These data indicated that the peduncle length of tomato was controlled by two pairs of dditive-dominant-epistasis major genes + polygenes.It was preliminarily judged that the epistasis effect of polygenes was different due to temperature changes,and the heritability of major genes was 46.61%-77.08%,The heritabilities of polygenes were all 0.These results indicated that the inheritance of major genes played a leading role in the genetic rule of peduncle length of tomato.
