| 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重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。

| Abstract: | 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 parthenocarpy (53.3%), 24 were medium (32%) and 11 were weakly parthenocarpic (14.7%). 20 out of the 24 cultivars 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. |
