以哈密地区“无核白”葡萄品种为试材,研究了不同斑叶蝉种群对葡萄生理指标的影响。结果表明:随着斑叶蝉种群增大,叶绿素含量降低;过氧化物酶(POD)和超氧化物歧化酶(SOD)活性随之增加;丙二醛(MDA)和可溶性蛋白质含量则降低。试验表明高密度的斑叶蝉可对葡萄造成相应的危害,葡萄自身可通过一些途径进行防御。 Taking Hami region “seedless white ” grape variety as test material, the effects of different leafhopper population on grape physiological index were studied. The results showed that the content of chlorophyll decreased with the increase of population of leafhopper. The activity of peroxidase (POD) and superoxide dismutase (SOD) increased subsequently. The contents of malondialdehyde (MDA) and soluble protein decreased. Experiments show that high density of leafhoppers may cause the corresponding harm to the grapes, the grape itself can be defensive by some means.
