采用不同催芽处理、储藏方法进行米槠种子发芽试验，并对11个地理种源的米槠种子进行种子千粒重、含水量检验和发芽试验，探讨米槠种子催芽、储藏技术及发芽率与种子千粒重、含水量的相关性。结果表明：1）用冷水浸泡24 h可使米槠种子发芽率比未催芽处理提高17.9%，还可缩短种子发芽周期将近一周。2）低温储藏（-4℃）可最大限度的保持米槠种子活性，越冬后种子发芽率与新鲜种子相比，发芽率仅下降3%，但种子发芽周期比沙藏增长了将近一周。3）米槠种子的发芽率与含水量存在着显著的正相关关系，含水量是影响米槠种子发芽率的主要因素之一，在贮种选种中，含水量的控制十分关键。本研究解决了米槠种子越冬储藏、催芽处理等关键技术，可为米槠育苗提供理论指导和技术参考。

In order to investigate the pregermination method, storage technology of Castanopsis carlesii seeds and the relativity between germination rate, water content and 1 000-grain weight, the seed germination test of C. carlesii was made using different pregermination treatments and storage methods , and the seed 1 000-grain weight , water content and germination rate on 11 geographic provenances of C. carlesii were detected. The result showed that, soaking the seeds for 24 h with cold water could make the germination rate up to 17.9%, and it could short germination period nearly a week. Low temperature storage (four degrees below zero) could keep the seed vitality utmostly, and the germination rate was just declined by three percentage points comparing with the fresh seeds. But the germination period of C. carlesii seeds which with low temperature storage was extended nearly a week comparing with sand storage. There was a significant positive correlation between the germination rate and water content of C. carlesii seeds. Water content of seeds was one of the main factors what affect germination rate, so the control of seed water content was the key to seed storage and seed selection. This study solved the seed storage overwintering and pregermination technology for C. carlesii seeds, and it can provide theoretical guidance and technical reference for C. carlesii breedling.
