瓠瓜(Lagenaria Leucantha Rusby.)原产于我国,是一种重要的瓜类蔬菜,其嫩果含有较多的维生素B。瓠瓜大多数品种是雌雄同株异花植物,其主蔓上很少着生雌花,只生雄花。应用植物激素可以控制瓠瓜的雌雄性别。据报道,瓠瓜经乙烯利处理后,单株的雌花数可成倍增加,但因结实率降低,产量却未能相应增加。为了解决这个问题,我们选用乙烯利和三十烷醇进行促花保果的试验,摸索了两种制剂对促控瓠瓜某些性状和提高产量的作用。 Lagenaria Leucantha Rusby. Originated in China, is an important melon vegetable, its tender fruit contains more vitamin B. Most varieties of cucumber is monoecious alliatic plants, the main man with little female flowers, male flowers only. Application of plant hormones can control the gizzard’s male and female sex. It has been reported that the melon melon treated with ethephon, the number of female flowers per plant can be doubled, but because of reduced seed setting, yield did not increase accordingly. In order to solve this problem, we used ethephon and triacontanol to make the flower and fruit preservation test, and explored the effect of the two preparations on some characters of promoting and controlling cucumber and increasing the yield.
