乙烯利对黄瓜生长发育的影响

Effects of Ethylene-applying on Cucumber Growth and Development

[目的]研究乙烯利的增产效果以及适合南方的使用处理方式。[方法]采用喷施、淋施的方式,设6个处理,调查了蔓长、节间距、叶片数、雌花和雄花数量、第一雌花节位等性状。[结果]结果表明,施用乙烯利后能显著抑制黄瓜蔓长的增加,缩短节间距,增加雌花,减少雄花数,对第一雌花的节位没有明显影响。6个处理中,1叶期淋施100 mg/L乙烯利对植株生长没有抑制作用,但能显著地增加雌花数,减少雄花数。[结论]施用乙烯利能否作为一项成熟的增产措施还有待于进一步观察其产量表现。

[ Objective ] The effect of ethylene-applying on cucumber yield-increasing and its suitable application method were studied. [ Method ] The method of ethylene-spraying and -showering on the cucumber was experimented, including 6 treatments. The length of vine, iuternode length, number of leaf, number of female and male flower, node position of first female flower and other traits of cucumber were investigated. [ Results ] The result showed that ethylene application can obviously inhibit the vine growth, shorten the internode length, increase the number of female flower and reduce the number of male flower. The treatments had no obvious effect on the node of 1st female flower. Among six treatments, the treatment of 100 mg/L of ethylene showered in 1st leaf period can increase obviously the number of female flower and reduce the number of male flower only. [ Conclusion ] It needed to be further observed for the ethylene application as a measure to raise cucumber yield.
