Abstract

Activities of superoxide dismutase (SOD)and perosidase (POD)in different series of the hybrid tulip tree were measured in different growth stages , and their relationship with growth traits were analyzed .The results showed that the activities were lower in early growth stage than in late stage while there was significant difference in activities of 2 enzymes in different series .Correlation analysis indicated that the activity of SOD was significantly correlated with height and collar diameter , which suggested the high activity of SOD would facilitate the growth of seedlings .In addition , the activity of SOD in 84.2 % of the hybrid families was higher than that in their parents , and activity of POD of 63.2 % of the hybrid series was in the middle level .The SOD could be used as one of physiology and biochemistry indices to evaluate and predict the growth of the hybrid tulip tree .[ Ch , 2 fig .3 tab . 10 ref .]
