黄瓜种株留瓜数和瓜位对种子质量的影响

以在我国北方推广面积较大的中晚熟黄瓜品种“西农58号”为试材,研究了种株上留瓜数和种瓜着生部位对种子质数的影响,并对播种后幼苗生长情况进行了分析。结果认为:留瓜数和瓜位对种子质量和产量有明显的影响;建议在黄瓜原种繁殖时每株只留第二位一个瓜较好,而为大田生产制种时,每株留一,二位两个瓜较理想。

Effects of Numbers of Cucumbers and Fruit Setting Positions on Seed Plants Upon Seed Quality of Cucumber(Cucumis Sativus L.)

with the medium and late-maturing cucumber cultivar- "Xinong No.58* cultivated on a large area as the experimental material, the effects of cucumber numbers and positions to be remained on the seed plants upon seed quality were investigated. Also, the growth of young cucumber seedlings was analysed. The results indicated that the numbers and positions of cucumber fruits to be remained on seed plants had an obvious impact upon seed quality andyields.lt is, therefore,suggected that when cucumber original seed reproduce, it be better to leave on cucumber at the second position per plant, and when seed production was carried out in the fields, it be desirable to leave two cucumbers at the first and second positions per plant.
