查询词典 Aphis

This dissertation studied the overcompensatory responses of cotton,Gossipium hirsutum L. plants to leaf loss, square loss and cell sap lossand the changes in some physiological and biochemical contents with timein the case of overcompensation. The artificial defoliation, early squareremoval and aphis colonization were used as three types of simulated ornatural herbivory. The target of this study is to elucidate thephysiological mechanism of cotton plant overcompensation for insectherbivory.
