摘要: 在蚜虫和蚕豆构成的种群作用系统中,证实蚜虫的取食危害能诱导植物几丁质酶活性的增加,并且诱导反应的强度与昆虫危害程度相关。实验结果表明,诱导效应能在植物体内传导,诱导反应随时间呈动态变化。综合目前几丁质酶的诱导研究,认为几丁质酶不是特异性的抗性蛋白,而是应激反应的伴随产物,并提出在逆境条件下植物的应激反应模式。

Abstract: Experiments are carried out to study the chitinase in Viola faba leaves induced by Aphis craccivora on the basis of an insect-plant interrelationship.It is found that insect stress can induce plants chitinase activity and plant stress reaction level is related to the insect luantity.A highest chitinase activity is determined in 21 days under insect feeding.The experiments also show that plant can transmit the messages of insect stress from upper to lower alld increase its chitinase activity.The stress reaction fluctuates with time.It's concluded that plants resistant mechanism is the same under any adverse situations,that is to say.plant has a kind of convergent physiological stress reaction, and the dynamics of its chitinase activity is only an accompanying phenomenon.
