烯效唑浸种对黄瓜的壮苗效应

研究不同浓度烯效唑浸种对黄瓜幼苗生长发育的影响。结果表明,烯效唑可抑制黄瓜幼苗徒长,使株高降低,比叶重增加,根冠比和壮苗指数增大,叶绿素含量增加,根系活性增强,在形态上和生理上表现出显著的壮苗效应;烯效唑对黄瓜有极显著的增产作用,以20 mg·kg-1处理最佳,促进增产的主要原因是提高了单株结瓜数。

Effect of Soaking Seed with Uniconazole on High Quality Seedling of Cucumber

The effects of soaking seeds with different concentrations of uniconazole (0,5,10,20,40 mg.kg-1) on the growth of cucumber seedling were studied. The results showed as follows, inhibited effectively excessive growth of cucumber seedlings, decreased shoot height, increased specific leaf weight and healthy index and root-top ratio, as well enhanced chlorophyll content and root activity. Uniconazole treatment increased yield of cucumber significantly by increasing fruit number per plant and 20 mg.kg-1 was the best of all concentrations.
