| 摘 要： | 研究了南方６省７个不同地理种源鹅掌楸幼苗在南京地区阳生生境中的生长表现，测定了２年生幼苗生长量差异和光合日进程中净光合速率差异。结果表明，就光生理而言，盐津、金平和资源等种源在南京地区的阳生生境中生长状态良好，铜鼓种源则生长较差。

| Abstract: | The seeds of Liriodendron chinense (Hemsl.)Sarg. povenances in China were collected and germinated for comparison of growth adaptatbility. The biennial seedlings in the same height and state of growth are chosen for provenance testing. Growth data and net photosynthetic rate of each provenance are mainly connected with the hereditary feature themselves(Tab.2). Yanjing and Jingping provenances, comparatively speaking, adapt to the full sunlight condition in Nanjing. |
