Abstract:
The thousand-seed weight,germination rate and vitality of seeds for Betula luminifera were studied.The results showed that the thousand-seed weight was different in various habitats,and varied with the age and the part of crown and fruit.The seed had a longevity of 32～37 days in general and with a characteristic of the rapid germination.The seed had a high germination rate during the early stage or perk stage of seed dispersal,and a lower germination rate during the end stage.The germination rate and vitality of mature seed reduced with the increase of the storing time,the change in seed germination was significantly different at the various ages and habitats.
Key words: Betula luminifera, Reproductive ecology, Thousand-seed weight, Seed vitality, Seed longevity
