Effect of Application of ABA on Physiological Characteristics of Chrysanthemum Under Drought Stress

Li Yan

Abstract

In order to explore the chemical control effect of exogenous ABA,the effect of different concentrations of exogenous ABA on physiological property of Chrysanthemumseedling under drought stress was analyzed.The results showed that after spraying exogenous ABA,transpiration rate and stomatal conductance decreased,exogenous ABA slowed the decline of leaf relative water content and chlorophyll content,increased the content of osmotic regulation substances,such as MDA and soluble sugar,and improved the resistance to drought.100mg·L-1 exogenous ABA performed the best.
