摘要

席草( Juncus effusus L.var. decipiens Buchen) 表面纵向条纹的深浅和数量是影响席草茎秆光洁度的主要因素基本组织周边沿切向分布的纤维束呈三层排列的大小维管束及分布在其中的纤维细胞的特殊排列使席草茎秆具有较好的坚韧性髓部细胞的特化富含气体的海绵状组织的形成及基本组织内出现的腔隙道使席草茎秆具有较好的弹性和耐压力
 

Abstract

The depth and amount of longitudinal stripe on the stem surface of Juncus effusus L .var. decipiens Buchen are the m ain facto r which affects its brightness and cleaning. Fiber bundles around ground tissue, three-lay er arranged vascular bundles and the fiber cells scattered in the vascular bundles make the stem gain fairly good fastness . Specialized pith cells, spongy-like tissues which are air-abundant and the canals in ground tissue all make the stem gain fairly good elasticity and endurance of pressure.
