Title : The inoculation with Mesorhizobium sp. improves considerably the growth of Astragalus armatus under lead-stress
Abstract:
The study investigates the potential of Mesorhizobium sp. to enhance the growth of Astragalus armatus under lead stress, a significant environmental challenge due to heavy metal contamination. Lead pollution adversely affects plant health and soil quality, necessitating innovative solutions for phytoremediation.
Objective: This research aims to assess how inoculation with Mesorhizobium sp. can improve the resilience and growth of A. armatus in lead-contaminated soils.
Methodology: The study involves isolating Mesorhizobium strains from local leguminous plants thriving in lead-rich environments. These strains are characterized for their nodulation efficiency and heavy metal tolerance. Subsequently, A. armatus seedlings are inoculated with these strains and grown contaminated soil with heavy metals.
Results: Preliminary findings indicate that inoculated plants exhibit significantly enhanced growth parameters, including root and shoot biomass, compared to non-inoculated controls. The presence of Mesorhizobium not only promotes nitrogen fixation but also aids in mitigating the toxic effects of lead, thus improving overall plant health.
Conclusion: The inoculation with Mesorhizobium sp. emerges as a promising strategy for enhancing the growth of Astragalus armatus under lead stress, offering a viable approach for bioremediation in contaminated ecosystems. This research highlights the importance of symbiotic relationships in plant resilience against heavy metal stress and supports the use of rhizobia in sustainable agricultural practices.
