Abstract:
Taking Rhododendron purdomii seed as material,the effects of light time and gibberellin(GA3) on Rhododendron purdomii seeds germination were studied,in order to provid a scientific basis for germplasm preservation and utilization of ?Rhododendron purdomii.The results showed there was little difference among the three light time on the starting germination time，germination rate，but under 800 mg/L GA3 conditions，the germination vigor of 24 h dark was much higher than the other two light treatments.After soaked 24 h with different concentration GA3，the starting germination time，germination rate and germination vigor were all dramatically enhanced.
