| Abstract: | Taken one-year old Camptotheca acuminata seedlings as trial materials,the changes of SOD activity、contents of Chl、MDA and pro have been studied under lower temperature intimidation. The results showed: SOD activity and the content of Chl have been reduced comparing to the comparison (30℃±2)under 8℃ for ten days,the extent was below differently:25 31%、11 91%,the contents of MDA and pro have been heightened,the extent was below:14 82%、50 72%;SOD activity and the content of Chl have been reduced comparing to the comparison under 4℃ for eighteen days,the extent was below:22 56%、37 19%,the contents of MDA and pro were been heightened,the extent as follow:29 42%、58 72%。 |
