中文摘要：
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。
英文摘要：
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.
