山东滨海盐生植物根结构的比较研究

Comparative studies on the root structure of maritime halophytes in Shandong

对山东沿海 1 0科 1 3属 1 3种盐生植物根结构的比较研究表明 ,长期生长在盐生环境中的植物 ,形成了某些相似的适应生境的结构特征 ,主要表现在 :1根中产生异常结构 ;2具有多个通气道 ;3薄壁组织发达 ;4根的表面保护组织增强。另外 ,有的植物根中有含晶细胞 ;

Comparative studies on the anatomical structure of roots of 13 maritime halophytes are carried out.In order to adapt to halophilic environment,these plants form some similiar structure.They are as follows:anomolous secondary structure;many air passages;well developed parenchyma;numorous layers of phellem or exodermis.Both Cynanchum thesioides and Messerschmidia rosmarinifolia have crystalliferous cells in their roots.Both Suaeda glauca and Limonium franchetii have tannin idioblast in their roots.
