摘　　要：为提高“南水8号”种子产量,以雌性系黄瓜“NW-6”、自交系“NY-m”为材料,授粉后观察花粉萌发以探究“南水8号”种子产量低的原因。以单瓜种子数、单瓜种子产量、百粒重、发芽率、发芽势5个方面为指标,采用单因素分析进行综合评价,选择对提高种子产量具有显著作用的激素。结果表明,“NW-6”与“NY-m”杂交后表现出类似远缘杂交障碍的现象;油菜素内酯对提高制种产量有显著作用,用浓度为0.080 mg/L的BR处理得到的单瓜种子数、单瓜种子产量最高,单瓜种子数可达91.27粒,单瓜产量达2.60 g,百粒重为2.93 g,综合评价最高。To increase the seed yield,the experiment used the‘NW-6’,‘NY-m’as the female cucumber material,and observed pollen germination to explore the reason of the low seed yield;seed number single melon,single melon yield,100-grain weight,the germination rate and germination potential were adopted to evaluate comprehensively by single factor.The test results showed that‘NW-6’and‘NY-m’showed similar remote hybrid disorder;canolein had a significant effect in improving seed production.The number of seed and yield of single melon by BR with concentration of 0.080 mg/L were the highest,the number of seed of single melon could reach 91.27,the yield of single melon could reach 2.60 g,and 100-grain weight was 2.93 g,which was the highest in comprehensive evaluation.
