Low temperature is one of the most important abiotic stress factors for crop plants. It has been frequently observed that supplementation of plants with Si as seed soaking, leaf spray, or root treatment alleviates the adverse effects of chilling stress and reduces frost damage in both Si-accumulator and nonaccumulator species. Mechanisms for the ef...

Selenium (Se) biofortification via crops is one of the best strategies to elevate the daily Se intake in areas where soil Se levels are low. However, Se fertilizer recovery (SeFR) is low and most of the Se taken up accumulates in non-harvested plant parts and returns to the soil with plant residues. A pot experiment with soil was undertaken to stud...
