整枝方式对甜瓜开花习性的影响

Effects of Pruning on Flowering Habits of Cucumis melo L.

选用甜瓜(Cucumis melo L.)品种(系)东甜001、No.3-2-2、Top Mark、WI 998为研究对象,对各品种(系)分别采用单蔓整枝、双蔓整枝及不整枝方式处理,研究不同整枝方式对甜瓜开花习性的影响。结果表明,甜瓜不整枝时,主要进行营养生长,开花较晚;而整枝能促进甜瓜进入生殖生长,提早开花,整枝还能促进某些甜瓜品种(系)开雌花(不整枝不开雌花)。不同整枝方式对甜瓜各品种(系)的着花习性影响除了东甜001雌花和雄花第一开花时间存在显著差异外,其他品种间对开花时间的影响差异不显著;此外,甜瓜双蔓整枝比单蔓整枝其雄花和雌花数量多,但差异不明显。

Using melon（Cucumis melo L.） cultivars Dongtian 001, No.3-2-2, Top Mark, WI 998 as materials, the effects of different pruning methods（single vine pruning, two branches pruning and without pruning） on flowering habits of melon were studied. The results indicated the flowers bloomed late and the plants growth was mainly vegetative without pruning. While pruning could promote reproductive growth, and bring forward flowering time, moreover, pruning also promote female flower blooming of some melon cultivars. The effect was not significantly different among different pruning methods for most cultivars except for the first male and female flowering time of Dongtian 001. The two branches pruning could promote female flower and male flowering opening than single vine pruning methods; but the difference is not significant.
