Synthesis of green nanoparticles from leaves of Cannabis sativa L. and its effective role on growth performance of tomato

There is a rising demand for eco-friendly, non-toxic synthetic biological procedures for the synthesis of nanoparticles. The goal of the experiment was to synthesize silver nanoparticles using fresh leaves of Cannabis sativa L. and their characterization and antifungal activities examined under in vitro conditions. Several biotic factors present in seeds and adversely affect their viability and germination. Green synthesis of silver nanoparticles applying procedure at specific set of conditions. Tomato seed treated with green synthesized nanoparticles significantly increased the germination rate and reduced the mortality of seeds. The highest germination as 92.66% and minimum seedling mortality with the value of 5.2% were found in seeds treated with silica nanoparticles at 100 ppm (T12) compared to non-treated seeds and remaining all treated seeds also indicate better germination as compared to control. The length, fresh and dry weight of root and shoot were highest observed in treatment T12 (silica 100 ppm) treated plants. As might be expected, green synthesized silver nanoparticles could be used as antimicrobial and plant growth promoting agent.
