Abstract:
OBJECTIVETo study the effects of HKL-4 on physiological changes during growth of leaves.
METHODUsing 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 CONCLUSIONThe 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.
