Geographic Pattern of Phenotypic Features of Phyllostachys pubescens in Natural Stands

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.
