[目的]通过对长尖叶墙藓植物生物学特性的研究,探讨耐旱及耐低温藓类植物的特征.[方法]取一部分新鲜的长尖叶墙藓,用超声波清洗仪进行清洗,扫描电镜观察并照相.[结果]叶干时紧紧贴于茎上,叶细胞多疣,中肋突出,叶尖呈毛刺状.[结论]长尖叶墙藓是适应干旱环境的苔藓植物类型.%[ Objective] The charaeteristics of mosses which have drought-tolerant and chill-tolerant traits were studied by investigating their bio-logical features. [ Method] After cleaning in an ultrasonic cleaning bath with distilled water,Tortula logimucrunula L. Was mounted on metal stubs for SEM and sputter-coated with gold. They were viewed and photographed. [ Result ] Leaves were appresaed to the stem when it was dried. Most warts covered on the surface of the leaves with midrib prominent. The shape of leaf opex is priekles. [ Conclusion ] Tortula logimucronata L. Adapt to arid environments.
