It is well known that different ecotypes adopt mechanisms to survive under environmental stress conditions. In this regard, each ecotype showed type of modifications for their existence in a specific habitat reflects ecological success.Here, differently adapted Bermuda grass [Cynodon dactylon (L.) Pers.] were collected evaluate differential structural and functional are cope with The soil adheres roots highly saline case DF-SD (Derawar Fort-Saline Desert), UL-HS (Ucchali Lake-Hyper Saline) G-SSA (Gatwala-Saline Semiarid) ecotypes. Soils S- HS (Sahianwala-Hyper Saline), S-SW (Sahianwala-Saline Wetland) PA-RF (Pakka Anna-Reclaimed Field) basic (pH 9 10).
