Abstract An investigation was carried out to evaluate ionic relation of roots on the basis of anatomical and physiological responses in differently adapted ecotypes of Typha domingensis Pers. under salinity stress. Six ecotypes were collected from ecologically different habitats in the Punjab namely Jahlar, Sheikhupura, Sahianwala, Gatwala, Treemu and Knotti. Plants were grown in non-aerated waterlogged conditions and subjected to different salt levels (0, 100, 200 and 300 mM of NaCl). The Sahianwala ecotype showed better performance under salt stress on the basis of structural modifications like thicker root, larger root aerenchymatous cavities and cortical cell area, and functional response like high K+ uptake and reduced uptake of Cl-. This ecotype also showed low reduction in root and shoot fresh weight as compared to all other ecotypes. The Knotti ecotype was the second best that relied on exceedingly large aerenchymatous cavities and reduced Cl- uptake for salt tolerance. The sensitive ecotypes from Sheikhupure and Treemu showed a significant decline in growth and most of the anatomical characteristics, in particular the root-cross-sectional area. Overall it was found that all ecotypes of Typha domingensis Pers. responded differently to salt stress, which indicates a heterogeneity on the root adaptive components.
