摘要
诱导抗虫性研究发现,应用茉莉酸甲酯(MeJA)诱导甘蔗后,其叶片及生长点组织中多酚氧化酶(PPO)活性明显提高,酶活性分别达22～50 units/mg和182～218 units/mg,这与模拟螟虫取食作用的机械损伤诱导作用结果相类似。
Research on induced resistance revealed that the activity of polyphenol oxidase increased considerably in the leaves and growing tips of sugarcane after methyl jasmonate induction. The activity reaches 22-50 units/mg and 182-218 units/mg respectively, similar to the induction of mechanical damage that imitates borer bites.
