【摘要】The effects of CPPU on fruit growth of Momordica ch arantia L.were studied.The result showed that 10mg.L－1，20mg.L－1 and 50mg.L－1 of CPPU accelerated the ovary growth and caused the fruit r ipen earlier than the control,when Momordica charantia L.ovary were soaked wit h CPPU solution at anthesis,and 1 day before or after anthesis respectively.Amon g them,20mg.L－1CPPU treated at anthesis was more effective.The fruit fres h weight and dry weight increased by 26.8％ and 7.8％ over the control respect ively. CPPU dramatically increased the fruit cell diameter in radical section, v ertical section and tangential section by 10.92％-35.42％,11.40％-40.97％ and 10.55％-28.38％,respectively,than the control.CPPU accelerated cell divis ion and growth at early period.This might be related to CPPU regulating endogeno us IAA,GA,CTK and ABA levels.%以中熟苦瓜品种蓝山大白为试材，用CPPU10mg.L－1 ，20mg.L－1,50mg.L－1和100mg.L－1在开花当天和花前3天，花前1天以及花后3天，花后1天处理苦瓜子房，研究了对苦瓜果实生长、膨大和产量形成以及营养品质的影响。同时，对CPPU促进苦瓜果实生长和膨大的机理作了研究。试验结果表明， 10mg.L－1、20mg.L－1和50mg.L－1的CPPU在开花前、后1天和开花当天处理苦瓜子房，有加速
