| 摘 要： | 以巴西橡胶树（Hevea brasiliensis Mull.Arg.）无性系PR107和热研7—33—97为试验对象，研究机械伤害、外源莱莉酸及乙烯（利）等条件对胶乳C-乳清中磷脂酶A2的影响。结果表明，伤害和外源莱莉酸及乙烯（利）对磷脂酶A2均有诱导作用。其中机械伤害的诱导效应最为明显，外源茉莉酸最适诱导浓度为0.08％，磷脂酶A2活性随着外源乙烯刺激剂量的增加而增强。伤害信号能在伤害早期较明显地诱导磷脂酶A2的活性。

| Abstract: | The effects of mechanical wounding(tapping),exogenous jasmonic acid and ethylene(ethrel) on phospholipase A2 activity in C-serum of Hevea clones PR107 and Reyan7-33-97 were studied.The results showed that tapping,exogenous jasmonic acid and ethylene(ethrel) stimulation could induce the activities of PLA2 in the latex.Inductivity of wounding was stronger.0.08% JA-stimulate dosage treatment was better.But the inductivity of ethylene wasn't in linear with ethylene quantity.The wounding signal barely induced PL... |
