Abstract Three potential sail tolerant fora e grasses (Cynodon dactylon, Imperata cylindrica and Sporobolus arabicus) were collected from the salt affected habitats in the Salt Range, Pakistan. Ecotypes of all the three grasses were also collected from normal non-saline habitats within the Faisalabad region. Mechanism of adaptation to saline environments is very specific, which is not only for grass species but also for ecotypes. Ecotypes of all three grasses from Faisalabad showed stunted growth under salt stress, perhaps to save energy for normal developmental and other metabolic processes. Salt tolerant ecotypes from the Salt Range had better growth and survival under saline conditions and had less reduction in shoot growth at the highest salt level as compared to those collected from non-saline habitats. Leaf area of tolerant genotypes was less affected by salinity than salt sensitive genotypes. Increased root growth as observed in C. dactylon and S. arabicus, can be attributed to better salt tolerance in the populations from the Salt Range. The ecotypes of all three grasses, C. dactylon, I. cylindrica and S. arabicus from the Salt Range performed better under high salinities than their counterparts from the Faisalabad region. On the basis of various morphological characteristics and growth attributes, the ecotype of S. arabicus from the Salt Range has been categorized the most tolerant among all the grasses and ecotypes. It was followed by the ecotypes of C. dactylon and I. cylindrica from the Salt Range.
