Abstract

To find out the relationship between the physiological and biochemical characteristics and the resistance under gradual drought of soil in three cultivars of black locust seedlings , three indexes including malondehyde (MDA)content , superoxide dismutase (SOD)and catalase (CAT)activities of anti-oxidation system were tested , The results showed that the accumulation of MDA increased under drought stress , while the activities of SOD and CAT first decreased then increased .The anti-oxidation enzymes activities of tetraploid black locust seedlings were significantly higher than those of the control under serious stress .It is concluded that tetraploid black locusts with higher drought resistance maintained relatively lower MDA content and higher activity of anti-oxidation enzymes .The indexes of protecting system could be used to fast and conveniently evaluate the drought resistance of black locust .
