| 摘 要： | 调查研究了我国17个天然毛竹林的胸径、中央直径、杆高、枝下高、全杆节数、枝下节数、叶片长度和宽度、叶片侧脉数、胸高处竹壁厚度、竹腔径、壁腔比等表型特征。研究表明,胸径、杆高、叶片长度和宽度、叶片侧脉数、竹腔径、壁腔比呈现随纬度变化的地理模式,与经度无关;全杆节数受经度和纬度的双重影响;所调查的表型特征均没有表现随海拔的变化而变化的地理变异模式。研究还表明部分表型特性与气候条件下具有显著或极显著的相关性。

| Abstract: | Seventeen Phyllostachys pubescens natural stands were selected to study the phenotypic features, such as DBH, center DBH, culm length, clear bole height, the node number of the culm, node number of clear bole, thickness of bamboo culm, the length and width of the leave,the number of vein, diameter of bamboo cavity,the ratio between diameter of bamboo cavity and thickness of bamboo culm. It is found that there exist longitude trends for DBH,culm length,the length and width of the leave,the number of vein,diameter of bamboo cavity,ratio between diameter of bamboo cavity and thickness of bamboo culm and less effected by latitude; that the node number of the culm is affected by both longitude and latitude; that other phenotypic features are less effected by longitude or latitude; that all surveying factors have no relations with altitude. Some phenotypic features have distinct relations with atmospheric condition. |
