Objective:
To compare and explore the physiological and biochemical index of virus-free seedling and common seedling of Chrysanthemum morifolium.
Method:
Leaves of virus-free seedling and common seedling were cut down and the contents of chlorophyll a and b, MDA, and the activity of SOD, POD, CAT, and the net photosynthetic rate (Pn) were measured.
Result And Conclusion:
The contents of chlorophyll and Pn of virus-free seedling were higher than those of common seedling. But were measured, the contents of MDA and the activity of SOD, POD, CAT related to the physiological resistance were lower than the latter. These could explain the phenomenon of virus-free seedling grow better than the common seedling under the same condition.
