Inhibition of toxic pollutants from tannery effluent by using am fungi and its response on green gram (Vigna radiata L.)
Mycorrhizal fungi intimately associate with plant root forming a symbiotic relationship. The mycorrhizal symbiosis in effluent polluted soils was documented and the effect of dual inoculation with AM fungus on the host plant greengram (Vigna radiata L.) in pot culture experiments were investigated at six concentrations of tannery effluent viz., control, AM only. 50% effluent, 50% + AM, 100% effluent, 100%+AM. AM inoculated plants significantly increased in all morphological parameters. When compared with uninoculated plants the morphological parameters such as root length, shoot length, fresh weight and dry weight, root nodules and phosphorous content of greengram were increased in AM fungi inoculation soil. This study provides evidence for benefits of AM fungi protection of host plants and symbiosis could be a new approach increase in the effluent tolerance to legumes plants under effluent stress.
