初步研究了茉莉酸诱导对小麦苗抗病虫能力的影响,结果显示,小麦在喷施茉莉酸后能够提高植株对麦长管蚜和小麦白粉病菌、小麦叶锈病菌的抵抗能力,可显著降低小麦白粉病、叶锈病的发病级别和病斑数量,对麦长管蚜则在体重和产仔数量上有显著的抑制作用。对小麦病虫的控制效果达40%
The effects of jasmonic acid induction on the resistance of wheat seedlings to pest and disease were preliminary studied. The results showed that the resistance of wheat to wheat leaf aphid and powdery mildew and wheat leaf rust could be significantly reduced after spraying jasmonic acid Wheat powdery mildew, the incidence of leaf rust disease and the number of spots on wheat aphid in the body weight and litter size significantly inhibited. The control effect on wheat pests reaches 40%
