Title Phytoremediation potential of some halophytic species for soil salinity
Source International Journal of Phytoremediation
Abstract Phytoremediation potential of six halophytic species i.e. Suaeda nudiflora, Suaeda fruticosa, Portulaca oleracea, Atriplex lentiformis, Parkinsonia aculeata and Xanthium strumarium was assessed under screen house conditions. Plants were raised at 8.0, 12.0, 16.0, and 20.0 dSm(-1) of chloride-dominated salinity. The control plants were irrigated with canal water. Sampling was done at vegetative stage (60-75 DAS). About 95 percent seed germination occurred up to 12 dSm(-1) and thereafter declined slightly. Mean plant height and dry weight plant(-1) were significantly decreased from 48.71 to 32.44cm and from 1.73 to 0.61g plant(-1) respectively upon salinization. Na+/K+ ratio (0.87 to 2.72), Na+/ Ca2+ + Mg2+ (0.48 to 1.54) and Cl-/SO42- (0.94 to 5.04) ratio showed increasing trend. Salinity susceptibility index was found minimum in Suaeda fruticosa (0.72) and maximum in Parkinsonia aculeata (1.17). Total ionic content also declined and magnitude of decline varied from 8.51 to 18.91% at 8 dSm(-1) and 1.85 to 7.12% at 20 dSm(-1) of salinity. On the basis of phytoremediation potential Suaeda fruticosa (1170.02mg plant(-1)), Atriplex lentiformis (777.87mg plant(-1)) were the best salt hyperaccumulator plants whereas Xanthium strumarium (349.61mg plant(-1)) and Parkinsonia aculeata (310.59mg plant(-1)) were the least hyperaccumulator plants.
