摘要

Application of nanoparticles (NPs) in agriculture 2021has emerged as a novel approach to enhance plant growth and productivity. This study was designed to evaluate the effect of chemically synthesized, roughly spherical CuS (copper sulfide) NPs (4.32 nm) on growth parameters, biochemical profile, yield, and oil content of Eruca sativa and Linum usitatissimum in pot experiments. Exposure to CuS NPs (≤ 40 mg Kg− 1 soil) promoted root and shoot length, branching, and biomass accumulation in both plants species. CuS NPs increased number of pod (70.04%), seeds per pod (50.57%), and oil content (29.26%) in E. sativa, while L. usitatissimum showed 35.80% increase in seed balls per plant, 34.76% seeds per ball, and 34.13% increase in oil content. The atomic absorption spectroscopy revealed accumulation of Cu in root > shoot > seed of both plants. CuS NPs triggered the production of non-enzymatic antioxidants (phenolics and flavonoids) and also increased level of antioxidative enzymes, peroxidase and superoxide dismutase in both plants. The plants also revealed increase in radical scavenging activity, total antioxidant capacity and total reducing power of oxidative stress on exposure to CuS NPs. Principle component analysis and hierarchal cluster analysis depicted grouping within the treatments based on the morpho-biochemical responses of both plant species. The results underscore that CuS NPs up to 40 mg Kg− 1 improved E. sativa and L. usitatissimum growth, biochemical resilience and yield productivity. Therefore, CuS NPs can be employed as novel stimulant for plant growth, productivity and oil content.
