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， ＣＰＰＵ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。
With medium-ripe bitter melon varieties Lanshan Da Bai as the test material, with CPPU10mg · L-1, 20mg · L-1, 50mg · L-1 and 100mg · L-1 on the flowering day and 3 days before anthesis, Three days after flowering and one day after flowering, the seeds of Momordica charantia were treated, and the effects on the growth, enlargement, yield formation and nutritional quality of bitter melon fruits were studied. At the same time, CPPU to promote bitter melon growth and enlargement mechanism was studied. The results showed that CPPU at 10 mg · L-1, 20 mg · L-1 and 50 mg · L-1 could improve the growth of bitter melon fruits on the day before flowering and on the day after flowering, Fruit weight and promote the early maturity of commodity fruit results. In the flowering day with 20mg · L-1CPPU treatment of bitter gourd ovary the best, fresh fruit weight increased by 26. 8% and 7. 8%. CPPU treatment promoted the early rapid division and cell growth of the bitter melon pulp cells, CPPU promotes the growth of individual cells is to promote fruit enlargement and early maturation of the direct cause.
