摘要

Nano-priming is a cutting-edge technique for treating seeds that enhances seed germination, seed growth, and crop yield by imparting resilience to several plant stressors. In agriculture, nanoparticles can serve as nanofertilizers and nanoinsecticides, contributing to future sustainable agriculture. The present study has evaluated the impact of various concentrations of copper oxide nanoparticles (CuO NPs) on three cultivated varieties of Vigna mungo. Surface-sterilized seeds were soaked in different concentrations of CuO NP solution, ranging from 1 to 1000 ppm. After the priming periods, seeds were placed on a Petri dish and maintained at room temperature. The germination percentage, various growth parameters, and seed vigour index were measured 7 days after sown (DAS). The evaluation of the impact of various concentrations of CuO NP found that 100 and 10 ppm produced the most favourable results, significantly enhancing the germination percentage, growth parameters, biomass weight, and vigour index. The findings of this study specified that the use of CuO NP enhances the germination, various growth parameters, and vigour index of V. mungo and may have potential applicability for experimentation on other crop species.
