[Effect of HKL-4 on active oxygen metabolism and photochemical efficiency in licorice leaf].
OBJECTIVE
To study the effects of HKL-4 on physiological changes during growth of leaves.


METHODS
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.


CONCLUSIONS
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.
