报道了鹅掌楸在苗圃播种后的出苗率和幼苗存活率，根据定期观察数据编制了苗期动态生命表．结果表明，４个种源的出苗率都很低（１．６４％～３．０５％），比其各自的饱满种子率低得多；天然种源的出苗率高于栽培的种源，但前者的出苗数占饱满种子数的比例却低于后者．至一个生长季以后，幼苗存活率仅占出苗数的１６％～２７％，而黄山种源与庐山种源的交配后代则高达６０％，明显地高于其亲本和其它种源．种子大小对于出苗率和幼苗存活率没有直接影响．最后讨论了遗传因素和生存环境对幼苗存活的影响，并认为种子和幼苗适合度低是鹅掌楸致濒的重要原因之一．
The seedling emergence rate and seedling survival rate of Liriodendron chinense after sowing in nursery were reported, and the dynamic life table at seedling stage was prepared according to the regular observation data. The results showed that the seed germination rates of four provenances were very low (1.64% ~ 3.05%), much lower than their respective full seed rates. The natural seed germination rate was higher than that of cultivated ones The former number of seedlings accounted for the proportion of seedy is lower than the latter. After one growing season, the seedling survival rate accounted for only 16% ~ 27% of the seedling emergence, but the mating progeny of Huangshan provenance and Lushan provenance were as high as 60%, significantly higher than their parents and other provenances. Seed size has no direct effect on the emergence rate and seedling survival rate. Finally, the effects of genetic factors and living environment on seedling survival were discussed. The low adaptability of seed and seedling was considered as one of the most important reasons for the success of Liriodendron bungei.
