坐瓜灵(KT—30,苯基脲类细胞分裂素,中国农科院郑州果树研究所生产)对提高西瓜坐果率有明显的效果。在大田生产中对提高甜瓜坐果率也有很好的作用。 甜瓜F_1制种,常因不能及时坐瓜而耗费大量杂交去雄、套袋的人力;且因坐瓜晚和坐瓜节位太高而影响制种产量。因此,能否在甜瓜杂交制种以及杂交育种中使用坐瓜灵,促进及时坐瓜,确保杂交成功是一个亟待研究的重要问题。但坐瓜灵在杂交制种甜瓜上应用,对种子数目及种子产量等各方面有何影响,国内外研究甚少。本试验在甜瓜制种上使用坐瓜灵,旨在摸清使用坐瓜灵后对种子数 Sitting on the melon (KT-30, phenylurea cytokinin, Chinese Academy of Agricultural Sciences Zhengzhou Fruit Research Institute) to improve the watermelon fruit set rate has obvious effect. In the field production to improve melon fruit set rate also has a good effect. Melon F_1 seed production, often because they can not sit in a timely manner and melon spent a lot of hybrid to male, bagging manpower; and sit melon late and sit melon knot too high and affect seed production. Therefore, it is an urgent issue to study whether the use of sitaglin during the hybridization and hybrid breeding of melon can promote the success of hybridization. However, the application of melon in melon hybrid production, the number of seeds and seed yield and other aspects of what impact, little research at home and abroad. The test in the melon seed production on the use of melon, designed to find out the use of squash after the number of seeds
