Fulvic Acid Enhances Oat Growth and Grain Yield Under Drought Deficit by Regulating Ascorbate–Glutathione Cycle, Chlorophyll Synthesis, and Carbon–Assimilation Ability

Fulvic Acid Enhances Oat Growth and Grain Yield Under Drought Deficit by Regulating Ascorbate–Glutathione Cycle, Chlorophyll Synthesis, and Carbon–Assimilation Ability

Drought deficit inhibits oat growth and yield. Fulvic acid (FA) can enhance plant stress tolerance, but its effects on regulating the ascorbate–glutathione cycle, chlorophyll synthesis, and carbon–assimilation ability remain unclear. Therefore, this study aimed to elucidate the physiological mechani...
