外源5-氨基乙酰丙酸对盐胁迫下决明幼苗生理特性的影响
*Effects of ALA on physiological characteristics of Cassia obtusi folia seedlings under salt stress
摘要
Abstract
In order to get the method to improve the salt resistance of seedlings for Cassia obtusi f olia under salt stress ,physiological characteristics of C .obtusi f olia seedlings were studied .Several physiological indexes of C .ob‐tusi f olia seedlings under salt stress like photosynthetic pigment ,superoxide anion(O‐2 .) ,malondialdehyde(MDA) , superoxide(SOD) ,peroxidase(POD) and catalase(CAT ) were measured .The rate of decrease was re‐lieved and the content of O . ,MDA decreased .The activities of three enzymes including SOD ,POD and CAT were increased by the treatment of ALA ,and reached the maximin(80 .0 U ・ g‐1 ,196 .4 U ・ g‐1 and‐2 114 .1 U ・ g‐1 respectively)with the concentration of 50 mg ・ L‐1 .ALA with concentration of 50 mg ・ L‐1 could significantly alleviate the damages to the seedlings of C .obtusi folia under salt stress ,and promote the salt resistance of the seedlings .关键词
