Effect of Silver nanoparticle (SNPs) on Protein and DNA Content of Tomato Seed Cucumber and Maze

Phytotoxic effects of manufactured or commercially available Silver Nanoparticles (SNPs) on L.esculentum (tomato), Cucumis sativus (cucumber) and Zea mays (maize) seeds were investigated by means of increase in root length, seed germination percentage and protein concentration. There was concentration dependent decrease in root length, germination percent and protein concentration and DNA content. The R 2 for root length of seeds treated with commercially available SNPs was 0.9282 (L.esculentum), 0.9625 (Z.mays) and 0.7329 (C.sativus). Concentration dependent decrease in germination percent was observed when SNPs was increased. Control seeds showed 100% germination. Seeds treated with 500ppm of SNPs showed a maximum germination of 43.3% for tomato, 30% for cucumber and 50% for maize. DNA content decreased in control and treated sample as (2.2 to 0.64) cucumber, (2.19 to1.2) tomato and for maize (2.46-1.1)?g/g, respectively.
