Seeds of Rhododendron chrysanthum Pall were pretreated by soaking for 24 h with GA3 at different concentiation gradients .And taking seeds with water soaking for 24 h as the control ,seed germination status were analyzed .The results showed that GA 3 seed soaking treatment could significantly increase the germination rate of Rhododendron chrysanthum Pall.Seeds soaked with 3 ×10 -4 GA3 for 24 h when the thermometer was at 23℃/15℃and light conditions was at 12 h/12 h,the starting germination time was 10 d,the seed germination rate was 86. 33%,the germination was 77.0%,the germination index was 41.70%.
