Effect of metallic-nanoparticles on morphological and biochemical charecteristics of Stevia rebaudiana bertoni

Abstract

Nanoparticles are ≤ 100 nm in size, exhibit different properties compared to the bulk material. In most of the reported NP studies on plant both positive and negative impacts have been observed.A pot experiment was conducted at field experimentation center, Department of biological sciences, sam Higginbottom University of agriculture Technology & sciences, Uttar Pradesh. during summer season 2019 with stevia. Effect of different metallicoxide nanoparticals on stevia with thirteen treatments and three replications each, were laid out in Radomized Block design. This research was under taken to asses the impact of different concentrations of zincoxide (25,50,75 ppm), copperoxide (25,50,75 ppm), zinc (10,20,30 ppm) and silicon dioxide (10,20,30 ppm) np’s on plant morphological growth, biochemical activities of Stevia. From the present investigation it was concluded that that the ZnO (50ppm) and CuO (50ppm) showed the most positive response in morphological and biochemical parameters.
