摘要
黄瓜单性结果品系EP-6授粉与不授粉处理花后均能正常发育,不授粉处理花后果实的发育显著慢于授粉处理,表现为单果重低、果形短、头部尖细,同时不授粉处理的果肉厚/果瓤厚值显著高于授粉处理;非单性结果品系YD-1、ZQ-1授粉处理果实均能正常发育而不授粉处理大多化瓜或果实发育畸形。从花前2d天至开花当天EP-6子房中IAA、ABA含量与POD活性均高于YD-1、ZQ-1;从开花当天至花后4d的子房(幼果),4个能正常结果的处理,IAA、ABA含量(单果)均上升而POD活性下降,2个未能正常结果的处理IAA、ABA含量(单果)仍维持低水平而POD活性上升。
The pollinated and non pollinated ovaries of parthenocarpic cucumber line EP 6 can develop, the development of pollinated ovaries were significantly faster than that of parthenocarpic ovaries, and the pericarp diametre/piacenta diameter data of pollinated ovares were significantly lower than that of parthenocarpic ovaries The pollinated ovares of non parthenocarpic cucumber lines YD 1 and ZQ 1 can develop, but the non pollinated ovaries not Two days before the anthesis, the POD activity and the contents of IAA, ABA in ovaries of EP 6 were higher than those of YD 1, ZQ 1 From anthesis to 4 days after it, in ovaries of three lines, no matter pollinated or not, there was a positive correlation between the contents of IAA, ABA(/fruit) and the fruit development; But a negetive correlation between the POD activity and the fruit development
