Abstract:
Taking Hippophae neurocarpa of Qinghai Qilian wetland and Hippophae rhamnoides ?from Huzhu and Huangzhong as materials，effect of natural state，GA，sand cumulative temperature and hydration dehydration treatment on germination character were studied.The results showed that the Hippophae rhamnoides natural germination rate was higher from Huzhu and Huangzhong，the natural germination rate of Hippophae neurocarpa seeds was very low in Qilian wetland；The germination rate and germination potential of Hippophae neurocarpa seeds had increased significantly on the sand cumulative temperature treatment for 60 days；GA and hydration dehydration treatment did not significantly increase the germination rate of Hippophae neurocarpa seeds.It showed that sand cumulative temperature could promote the germination of Hippophae neurocarpa seeds from Qinghai Qilian wetland.
