| 摘 要： | 2007年在敦煌市以烟粉虱-棉花为模式,研究了棉花在烟粉虱胁迫下化学防御的生理生化特征.在不同虫口密度下,测定了棉花叶片中超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)、抗坏血酸过氧化物酶(APX)、类胡萝卜素(Car)的动态变化.结果表明,烟粉虱作用后,棉株叶片SOD、POD、CAT和APX活性与虫口密度呈正相关,而类胡萝卜素含量与虫口密度呈负相关.距虫源10 m处SOD、POD、CAT、APX活性和类胡萝卜素含量变化大于距虫源20 m处.

| Abstract: | A field experiment based on the cotton-Bemisia tobacci interaction system was carried out in 2007 in Dunhuang City,Gansu Province,in order to study the physiological and biochemical characteristics of cotton(the cultivar 'Dunmian V3') in chemical defense under the stress of the insect Bemisia tobacci.The dynamic changes of six physiological and biochemical indexes such as superoxide dismutase(SOD),and peroxidase(POD),and catalase(CAT),and ascorbate peroxidase(APX),and carotenoid(Car) in the cotton leaves in... |
