Exogenous Ca2+ alleviates nitrogen and water deficit, and improves growth of wheat (Triticum aestivum) seedlings exposed to high temperature

This study was designed to examine whether exogenous Ca2+ would improve nitrogen nutrition, water status and growth of high temperature (HT)-stressed wheat (Triticum aestivum) seedlings. Wheat plants were exposed to 35/30 and 25/20°C as temperature control. Some of HT-stressed plants were simultaneously treated with 4 mM Ca2+. External Ca2+ could obviously improve growth of HT-exposed wheat seedlings indicated by the biomass. Compared with...
