Comparative metabolic responses and adaptive strategies of wheat (Triticum aestivum) to salt and alkali stress

摘要

BackgroundIt is well known that salinization (high-pH) has been considered as a major environmental threat to agricultural systems. The aim of this study was to investigate the differences between salt stress and alkali stress in metabolic profiles and nutrient accumulation of wheat; these parameters were also evaluated to determine the physiological adaptive mechanisms by which wheat tolerates alkali stress.
