Abstract excerpt
Effects of zinc (Zn) deficiency on shoot metabolites were investigated in contrasting rice (Oryza sativa L.) genotypes with special focus on ascorbic acid (AsA) biosynthesis, recycling, and catabolism. The genotypes IR74 (sensitive) and RIL46 (tolerant) were subjected to -Zn and control treatments for 3 weeks, and samples were taken at three different stages representing the pre-stress phase, emergence of visible...
