Exogenous Melatonin Compensates for Moderate Nitrogen Reduction in Upland Rice by Optimizing Leaf Nitrogen Allocation and Photosynthetic Metabolism

ABSTRACT Moderate nitrogen (N) reduction can lower production costs in upland rice but may constrain photosynthesis, N assimilation, and yield formation. Melatonin has the potential to regulate photosynthesis and nutrient metabolism; however, whether it improves the effectiveness...
