Abstract

The inoculation of arbuscular mycorrhizal (AM) fungus is seen as a possible biotechnological method for the environmentally friendly treatment of dangerous pollutants. A greenhouse experiment was conducted to analyse growth, biomass, chlorophyll and carotenoid content in Leuceana leucocephala seedlings inoculated with 2AMF (Glomus macrocarpum and Glomus fasciculatum) under arsenic stress (0, 25, 50, 100 mg/kg soil) for 3 months. Treatments was arranged in randomized complete block design. Outcomes of study shown that arsenic has impacted plants negatively whereas the plants inoculated with AMF (both) had impacted their growth positively. AMF inoculated plants shown significant increase in plant growth, biomass, chlorophyll and carotenoid content. Our results suggest that Glomus macrocarpum and Glomus fasciculatum both an effective bio-inoculant of Leuceana leucocephala for adverse effect under arsenic stressed soil. And Leuceana leucocephala showed a fair tolerance ability for arsenic soil contamination.

Conclusion

In the present study revealed that growth parameters and photosynthetic pigments of Leuceana leucocephala were reduced by arsenic stress in soil. The combination of arsenic stress and AMF (Glomus fasciculatum and Glomus macrocarpum) results in positive growth of all seedlings for all parameters. Whereas Glomus fasciculatum has higher responses than Glomus macrocarpum and control. Photosynthetic pigments were more affected by higher arsenic concentration (50 and 100 mg/kg soil), where at 25 mg/kg soil arsenic level impacts are marginal. Phytoremediation is an effective and efficient method for getting rid of heavy metals from toxic environment. There is need to identify new hyper-accumulator plant species that are more tolerant to Arsenic and also enhancing the capacity of existing accumulators by various means.
