| Abstract: |
| 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. |
