| Abstract: | The effect of chitosan(CS) on cold resistance of banana(Musa paradisiaca L.) seedlings was studied.The results showed that exogenous CS could reduce cell peroxidation and membrane permeability, prevent thedecreases of superoxide dismutase(SOD) and peroxidase(POD) activities, and increase the catalase(CAT) activity.The best effect of CS was 0.3%. |
