Abstract

Crops are destroyed by extreme heat, which also limits their growth and yield. The present study sought to determine whether selenium (0, 15, or 30 mg l-1) impacted 'Barhee' date palm seedling's development under heat stress (in the field and canopy temperature). The growth parameters, chlorophyll and relative water content, ascorbic acid, catalase activity, and phytohormones in seedlings were reduced under heat stress. At the same time, ascorbate peroxidase activity, proline, phenols, malondialdehyde, hydrogen peroxide, and abscisic acid in seedlings increased. Enhancing growth features, chlorophyll content, relative water content, ascorbic acid, catalase activity, plant hormones, proline, phenols, and ascorbate peroxidase activity with exogenous nano-Selenium (15 mg l-1) reduced the negative impacts of heat stress. Date palm seedlings can be protected from high temperatures by using nano-selenium. Selenium reverses heat-induced oxidative damage by enhancing the antioxidative mechanism, improving reactive oxygen species scavenging, lowering lipid peroxidation, and modulating plant hormone levels.
