| 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。

| Abstract: | 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 |
