Abstract: (16 Views)
Drought is one of the most important environmental stresses that disrupts plant physiological and biochemical processes, thereby limiting growth and productivity. Identifying compounds that alleviate stress effects on plants is crucial. To assess the impact of water deficit stress [100, 50, and 30% field capacity (FC)], along with biochar application (0 and 20 g kg-1) and foliar spraying of silica nanoparticles (0 and 3 mg L-1), on the growth and some physiological traits of the almond cultivar Shokoufeh, a factorial experiment was conducted following a completely randomized design in the research greenhouse of Shahid Madani University of Azerbaijan. Irrigation at 100% and 50% FC, combined with biochar and silica nanoparticle foliar spraying, increased biomass, chlorophyll a, and phosphorus and potassium content in plants. The highest levels of nitrogen and calcium were observed with irrigation at FC combined with biochar application and silica nanoparticle spraying. The highest activities of catalase and superoxide dismutase enzymes, as well as proline content, were observed in the irrigation treatment at 30% FC combined with both levels of biochar and foliar spraying. Irrigation at 30% FC increased H2O2 and malondialdehyde contents in the plants. The results demonstrated that the combined application of biochar and foliar spraying of silica nanoparticles serves as an effective strategy to enhance growth and drought tolerance in the almond cultivar Shokoufeh under water deficit conditions. Optimal irrigation management in conjunction with these amendments can improve plant growth under drought stress by enhancing physiological traits and mitigating oxidative stress.
