Abstract:
Seeds of Rhododendron irroratum were used as materials and soaked by different concentrations of GA3 solutions(100,250,500 mg?L-1).The germination rate and physiological index of Rhododendron irroratum were determined to study the mechanism of improving seed vitality.The results showed that the germination rate could significantly improved by soaking with GA3,the germination rate was the highest when GA3 concentration was 250 mg?L-1.SOD and POD activities were significantly enhanced by soaking with 250 mg?L-1 GA3.CAT activity was significantly enhanced by soaking with 100 mg?L-1 GA3.The contents of MDA and soluble protein were significantly reduced by immersing with GA3.SOD,POD activities and soluble protein content were significantly correlated with seed vigor index.
