| 摘要: |
| 研究以2003年在广东省范围内所选枫香Liquidambar formosana优树为试验材料，对其进行进行表型分析，着重研究其生长与叶果性状。结果表明：枫香在广东以天然林为主，少量分布在人工林中；树龄集中在20~30 a，其次是30~50 a；胸径、树高生长性状分析表明5株优势木法选出的枫香优树是合理的，以现有资源中最优的种质材料为遗传改良的基础材料，该批优树胸径与5株优势木平均胸径差异幅度大于20%的有52株，占78.8%，枫香优树胸径年均生长量在0.5~2.0 cm之间的有126株，占总数的94.1%；枫香优树大部分树高年均生长量在0.7 m以下，共98株，占75.9%。高径比大部分集中在30~60，共93株占70%。方差分析结果表明：枫香优树的叶果性状在个体及种源间均呈极显著差异（P＜0.000 1）。 |

| Abstract: |
| In this study, the superior trees of Liquidambar formosana, which were selected from Guangdong province in 2003, were used for phenotypic analysis of trait growth, leaf, and fruit. The results showed that, L. formosana are mainly distributed in natural forests rather than plantation forest; the tree ages are ranged from 20-30 a, followed by 30-50 a. Phenotypic analysis of trait DBH and height indicated that the maple tree selected by the five dominant wood methods was reasonable and optimal in the existing resources of L. formosana superior trees, which were used for genetic improvement, there were 52 excellent trees with the differrence of DBH between the DBH and the dominant tree diameter of more than 20%,accounting for78.8%,there were 126 trees with the average annual growth of tree DBH between 0.5-2.0 cm,accounting for94.1%;there were 98 trees ,which the average annual growth of the height growth was less than 0.7 m,accounting for 75.9%.There were 93 trees with height-diameter ratios in 30-60,accounting for 70%.Variance analyses revealed that the leaf and fruit traits of L. formosana superior tree were significantly different among individuals（P＜0.000 1）. |
