Comparative studies on the root structure of maritime halophytes in Shandong

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.
