Abstract:

Biosynthesis of nanoparticles from living plant extracts can be used for conversion of metal ions into nano form. These nanoparticles are capable in controlling plant growth. If nanoparticles can enhance the growth of plants, it will be a great boon to the agricultural domain of developing countries that are particularly facing great challenges in order to improve the agricultural sector. Lawsonia innermis (henna) is a plant with various ethnomedicinal and antimicrobial activities. The chemical constituents of L. innermis include β-sitosterol glycoside, xanthones, flavonoids, coumarins, gallic acid, lawsone, etc., responsible for its activity. Manganese is one of nine essential micronutrients for plant growth. Synthesis of Ag nanoparticles has been reported by aqueous extract of Lawsonia innermis but not much work has been done on the synthesis of manganese nanoparticles. Present study was done with an aim to synthesize manganese nanoparticles by aqueous extract of Lawsonia innermis and effect of biosynthesized manganese nanoparticle on the growth of Cicer arietinum. For nanoparticle synthesis, 10% aqueous extract of plant is mixed with 10-3M MnSO4 solution and incubation of this reaction mixture was done at room temperature for 48 hours. Formation of nanoparticles was confirmed visually by the reaction mixture colour which turned to brown and the characterization of nanoparticles was done by UV-Vis Spectroscopy and Particle Size Analysis. Results suggests that biosynthesized nanoparticle treatment significantly enhance all the growth parameters i.e., fresh weight, dry weight, root length and shoot length of Cicer arietinum as compared to other treatment.
