Abstract:
One of the most significant environmental issues facing by experts in recent years has been the heavy metal poisoning of agricultural soils. The environmental pollution caused by heavy metal hazards in soils is harmful for both humans and wildlife. Chromium is a poisonous heavy metal whose extensive use and decomposition results in significant emissions into the soil. Higher level of Chromium have attracted worldwide attention as they can pose a toxic hazard to plants, animals and humans. Heavy metals from agricultural soils have been eliminated through the application of phytoremediation. The physical and chemical phytoremediation is less expensive. Nanomaterials act in phytoremediation, eliminating toxins directly from plant parts and promoting plant growth. To study heavy metal (chromium) accumulation in individuals of the Mimosa family (Acacia jacquemontii Benth). The five treatment levels (0, 25, 50, 75, and 100 µM) are given with or without Cobalt Nanoparticles were selected using three replicates. Information was recorded for morphological parameters like root, leaves and stem. To study the morphological/physiological responses of Acacia jacquemontii (Benth) under field conditions, determine its compositional arrangement, and use of the species in soil improvements. Chlorophyll a content were increased gradually when compared with controlled plants on the other hands chlorophyll b contents of a plant treated with T1 show increased as compared to T4. The plant treated with 100pm cobalt nanoparticle showed decreased antioxidant like TPC, TFC, DPPH as compared to TRP, TAC plant treated with 75ppm,50ppm,25pm concentration. Some important research problems addressing the biochemical behavior of Chromium in plant systems. Chromium accumulation induced both physiological and chemical changes in the plant. The results demonstrated that foliar application of Nanoparticles showed positive effect on the growth of plant. The result showed that Acacia jacquemontii can tolerate Chromium toxicity and have the ability to tolerate Chromium to some extent and hyperaccumulate.
