Seed Characteristics of Rhododendron Lingbaoense and Impact of Gibberellin on Germination
This research conducts a research on morphological characteristics,water absorption and the effects of gibberellin treatment on seed germination of Rhododendron lingbaoense.The results show that the seeds of Rhodo-dendron lingbaoense present cone-shaped and small seeds.In the process of water absorption,the the fastest water absorption rate of seeds is in 0～2 h,then the water absorption rate decreases rapidly,and the seeds reach satura-tion at 18 h.Meanwhile,GA3 soaking treatment improves the germination rate and germination potential of seeds,and improves the germination rate and uniformity of seeds,but the soaking time has little effect.Finally,steriliza-tion treatment affects seed germination,and the method by using 8%NaClO sterilization followed by GA3 treatment significantly increase the germination rate.
