赤霉素(GA_3)与茉莉酸甲酯(MeJA)对雾培马铃薯内源激素与生长发育的影响

Effect of Gibberellins(GA_3) and Methyl Jasmonate(MeJA) on Endogenous Hormones and Development of Potato in Aeroponics

试验以品种为主区,激素处理为副区进行裂区设计,研究了赤霉素(GA3)与茉莉酸甲酯(MeJA)对雾培马铃薯内源激素与生长发育的影响。结果表明:外源GA3处理增加了3个马铃薯品种叶片内源IAA和JA的含量,降低了中晚熟品种高原7号的内源ABA含量。外源MeJA对马铃薯块茎均有一定诱导作用,但结合GA3处理其诱导结薯的能力会减弱。

This test used split-plot design to study the effect of GA3 and MeJA on endogenous hormones and development of potato in aeroponics, with main plot being varieties and split-plot being hormones. The result indicated that the content of endogenous IAA and JA of all varieties increased while endogenous ABA of the Variety Gaoyuan 7 decreased when potato leaves were treated with extraneous GA3. Extraneous MeJA had inducement effect on tuber formation, but this effect was weakened while potatoes were treated with MeJA and GA3 together.
