Effect of NaCl Treatment on Phisiochemical Properties of Phyllostachys praecox cv.prevernalis
Determination was conducted on SOD and POD activity and MDA content in leaf of potted Phyllostachys praecox cv. Prevernalis under different NaCl treatments(0, 0.1%, 0.3%,0.5%). The result showed that different NaCl treated Ph. Praecox cv. Prevernalis could hold high SOD activity, and even higher than the control at the later period. POD activity in leaf under high stress decreased a little than that of the control at the later tage, but similar at earlier stage and even higher evidently at middle state. POD activity in leaf under medium stress was higher and similar that that of the control at middle and later stage. POD under low salt stress had no evident difference of both treated bamboo and the control. MDA content in leaf of treated bamboo had no great difference with that in the control, it had no close relationship among different physiochemical properties under different salt stress. The result demonstrated that medium salt stress treated bamboo could hold high SOD and POD activity and low MDA content, indicating Ph. Praecox cv. Prevernalis had salt tolerance under 0.3% of Na+ during short time.
