| 摘 要： | 偏序钝叶草（Ｓｔｅｎｏｔａｐｈｒｕｍｓｅｃｕｎｄａｔｕｍ（Ｗａｌｔ．）Ｋｕｎｔｚｅ）与地毯草（Ａｘｏｎｏｐｕｓｃｏｍｐｒｅｓｓｕｓ（Ｓｗａｒｔｚ）Ｂｅａｕｖ．）均为热带和亚热带的草坪优良草种，它们的匍匐枝节节可生根和产生分蘖，覆盖面积大。偏序钝叶草根毛分布范围较广，寿命较长；地毯草植株平铺地面，它们都是良好的保土植物。偏序钝叶草茎和叶的维管束都较密集，厚壁组织较发达，植株有一定的韧度。它们的叶的维管束解剖呈现“花环”结构，属Ｃ４植物。

| Abstract: | Stenotaphrum secundatum(Walt.)Kuntze and Axonopus conpressus(Swartz)Beauv.are good lawn grass species in tropical and subtropical zones.Their stoloniferous stems producing roots and tillers in each node cover a large area. The widely developed and well maintained root hairs of S.secundatum and the creeping character of A.compressus show that both plants are the promising plants for soil conservation.Anatomical study indicates that the densely arranged bundles and well developed sclerenchyma in the stem and leaf of S.secundatum make the plant tenacious.The dissections of vascular bundles in leaves of both species show garland structure,and thus,they are considered as C.plants. |
