Objective:
To study the effects of HKL-4 on physiological changes during growth of leaves.
Method:
Using licorice (Glycyrrhiza uralensis) as material, the effects of HKL-4 on active oxygen metabolism and photochemical efficiency in licorice leaf were determined under field condition.
Result And Conclusion:
The contents of chlorophyll, activity of SOD and CAT increased, while the MDA contents in leaves decreased. The senescence was delayed, so that the photochemical efficiency (Fv/Fm) was increasing comparing to the control.
