Enhanced Stomatal Conductance Supports Photosynthesis in Wheat to Improved NH₄⁺ Tolerance.

ABSTRACT: The impact of ammonium (NH₄⁺) stress on plant growth varies across species and cultivars, necessitating an in-depth exploration of the underlying response mechanisms. This study delves into elucidating the photosynthetic responses and differences in tolerance to NH₄⁺ stress by investigating the effects on two wheat (Triticum aestivum L.) cultivars, Xumai25 (NH₄⁺-less sensitive) and Yangmai20 (NH₄⁺-sensitive). The cultivars were grown under hydroponic conditions with either sole ammonium nitrogen (NH₄⁺, AN) or nitrate nitrogen (NO₃^-, NN) as the nitrogen source. NH₄⁺ stress exerted a profound inhibitory effect on seedling growth and
