【摘要】 对东亚特有濒危植物尖叶拟船叶藓4个地点9个居群叶的形态变异进行了初步观测.结果表明,7个形态指标除叶表外,叶的形状、叶细胞形状、叶基部反曲和宽窄程度、叶边缘的分化及齿的类型和数量、叶尖和中肋的相对长度等均存在一定程度的变异,尤其是后三者变异程度较大.在梵净山的4个居群中,随着海拔的上升,叶的宽度递减和长度递增,叶缘齿的数量递减,叶尖和叶中肋的相对长度却以中度海拔的居群较大.更多还原

【Abstract】 Morphological variance of nine populations in Dolichomitriopsis diversiformis (Mitt.)Nog.from four locations was observed.The result showed there some variance in the seven morphological characteristics of leaf (the shape,base,edge,tip and vein) except the surface,in particularly the three latter.With the altitude goes up,the breadth of leaf decrease and the length increase,the number of the tine of edge decrease,but the length of tip and vein of the medium altitude population are bigger.更多还原
