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，有加速苦瓜果实的生长、促进果实膨大、增加单果重和促进商品果提早成熟的效果。以开花当天用20mg.L－1CPPU处理苦瓜子房效果最好，单果鲜重分别增加26.8％和7.8％。CPPU处理促进了苦瓜果肉细胞的早期快速分裂和细胞个体生长，CPP U促进细胞个体的长大是促进果实膨大和提早成熟的直接原因

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.
