Sargassum-synthesized ZnO nanoparticles induce salt tolerance in maize plants through enhanced physiological and biochemical mechanisms.

ABSTRACT: Salinity is one of the biggest limitations of agriculture in semi-arid regions of the world. It negatively impacts the growth and yield of Zea mays L. Especially the seedling stage is extremely sensitive to salt stress. Sargassum tenerrimum J. Agardh. is a macroalgae which produces a plethora of important secondary metabolites, micro and macro-nutrients, polyamines and natural phytohormones etc. These compounds have been reported to improve plant growth and alleviate the harmful effects of salt stress. The current study explores the effectiveness of algal based Zinc Oxide nanoparticles (ZnOSt-NPs) in alleviating NaCl stress in Zea mays. The study involved two levels of NaCl (0 = control and 200 mmol kg- 1) and four levels (0, 30, 60 and 80 ppm) of ZnOSt-NPs applied through foliar spray. A
