摘要
在春季日光温室条件下,对75份黄瓜种质资源的单性结实性进行了评价。结果表明:75份材料的单性结实率在0～100%呈连续分布,其中强单性结实材料40份,占53.3%,中等单性结实材料24份,占32%,弱单性结实材料11份,占14.7%。其中的24份品种资源中,强单性结实品种20个,占83.3%,其余为中等单性结实。单性结实性强弱表现为坐果率的差异,不同种质资源无籽果实与有籽果实的单瓜质量和瓜形指数基本相似。单性结实性一般随着节位升高而增强,其评价工作可侧重于20节内的低节位。
Parthenocarpy of 75 cucumber germplasm and cultivars was evaluated under greenhouse condition in spring season. The results showed that the parthenocarpy percentage of 75 accessions was continuously distributed from 0 to 100%. While 40 accessions were found strongly parthenoearpy （53.3%） , 24 were medium （32%） and 11 were weakly parthenoearpic （14.7%）. Twenty out of the 24 cuhivars were found as strong parthenocarpy （83.3%）, and the rest was mid-parthenocarpy. The degree of parthenocarpy was expressed by the fruit set capability, and the fruit weight and fruit shape index of the seedless fruit present a good similarity with that of the seeded. The cucumber plants get stronger parthenocarpic with the nodes increase and the best evaluation should be done under 20th nodes.
