| 摘 要： | 红栲种子具有休眠特性,林下环境中红栲种子比林窗环境中早出苗。林窗中红栲种子成苗率显著高于林下红栲种子成苗率,同样是无盖网埋藏深度2 cm的处理,林窗红栲种子成苗率为7.2%,林下为1.6%。在林下,无盖网埋藏深度0cm、2 cm5、cm 3种处理,红栲种子成苗率分别是4.0%、1.6%和0.8%,红栲种子的埋藏深度与成苗率之间呈负相关。

| Abstract: | Seeds of Castanopsis hystrix have the phenomenon of dormancy.The seed emergence in undergrowth environment is earlier than that of forest gap one.But the seedling survival rate of Castanopsis hystrix in the forest gap was obviously higher than that of the undergrowth.The seedling survival rate of uncovered disposal buried in 2 cm depth in the forest gap was 7.2%, and that of the undergrowth was 1.6% only.In the forest environment,the seedling survival rate of uncovered disposal buried at the depth 0,2,5 cm were 4%,1.6%,0.8%,respectively,which showed the seedling survival rate was negative correlation with buried depth. |
