- 摘要:
- 以青海祁连县湿地的肋果沙棘和互助、湟中县的中国沙棘种子为试材，研究自然状态、GA、砂积温和吸湿回干处理对沙棘种子萌发特性的影响。结果表明：互助和湟中县的中国沙棘的自然萌发率较高，祁连县湿地的肋果沙棘自然萌发率较低；肋果沙棘经砂积温处理60 d后，种子的发芽率及发芽势有明显的提高；GA和吸湿回干处理不能显著提高肋果沙棘种子的发芽率；说明适当的积温处理会促进青海祁连湿地肋果沙棘种子的萌发。
- 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.
