Abstract:
Field experiments were conducted in two successive growing seasons (summer-autumn and spring-summer) to determine the effects of fruit length, fruit type and plant density on the seed yield and seed germinability in cucumber (Cucumis sativus L.). A genetically mixed population was used in the autumn and four culinary fruit-type cultivars in the summer. In the autumn experiment neither the number of seeds per fruit nor the mean seed weight varied among wide ranges of fruit lengths and weights. In contrast, in the summer experiment there were significant differences in seed yield per fruit among the four cultivars: seed yield increased with increasing fruit weight. The results of the two experiments differed also in seed quality, as expressed by germinability. In the autumn there was a positive correlation of both fruit length and weight with the germination percentage at optimal or super-optimal temperatures; in the summer, even among cultivars that differed significantly in fruit length and weight, there was no such correlation. Seed dormancy did not play any important role, at least in the summer experiment, and there were only negligible differences in seed germination percentages at seed harvest and after four years of storage. Plant density had a strong effect on seed yield per unit area, mainly by affecting the fruit number per unit area. Increasing the plant density up to 8-16 plants/m2 significantly increased the fruit number and only slightly decreased the seed yield per fruit, resulting in seed yield increase per unit area. Seed number per fruit and mean seed weight were affected by growing season and the tendency to parthenocarpy, which may eliminate any effect of the fruit length or weight. However, the fruit number is the dominant component of seed yield and culture practices have to maximize it in order to achieve maximum seed productivity.
