摘要
乙烯利作为一种外源化学因子,可诱导番茄、豌豆和萝卜等植物一系列的防御机能,使作物产生全面的抗病性,为植物病害的防治开辟了一条新途径.研究表明:乙烯利在适合浓度下,对大豆叶片内的总多酚、总黄酮、PAL活性和几丁质酶活性等与抗病性密切相关的生化指标均具有很好的诱导作用,其中0.01μg/mL的乙烯利对总多酚的诱导作用最强.乙烯利对大豆体内不同的抗性物质具有相似的生化诱导抗性机制.
Ethylene as a chemical factor can induce the production of resistant substances in tomato, pea and radish. The results show that the induction of total polyphenol content, total Flavonoids content, PAL activity and chitinase activity in soybean leaves are very good by ethylene of chemical factor at appropriate concentration, but the induced effect of total Polyphenol content is the best by ethylene of 0.01 μg/ml. The biochemical resistant mechanisms of induction are similar for different substances of biochemical resistance in soybean by ethylene.
