Abstract
Lepiochloa fitsca is known to be a versatile, halophytic, primary colonizer, G4, easily propagatable. perennial, thermophilic. nutritive and palatable forage plant species. Its shoot and root growth under various isosmotic substrate concentrations, e.g. 0.5, 0.75 and 1.0 Mpa of NaCI, Na2So4, CaCfc Mgcfc and Mgso4 (0.25 and 0.5 Mpa), was studied in gravel culture. The results clearly indicate that NaCI caused minimum inhibition in growth of both shoot and root followed in order by Na2S04, Cacfc and MgCfc. Na+ was the most compatible cation while CI" was less toxic than SO4 as the anion. The efficient excretion of salts through salt glands (as seen in SEM) indicated more absorption and subsequent excretion of Na+ and CI than Ca , Mg2 " 1 " and K+ at all salinity levels. The extensive development for roots under Na+ and CI" dominant root environments alongwith more excretion of these ions than others make it a suitable plant for economic utilization and even biological amelioration of saline-sodic and sodic soils.
