Differential effects of coumarin on root growth and nitrate uptake kinetics in nitrogen-contrasting wheat germplasm lines
Enhancing Nitrogen Use Efficiency (NUE) is critical for sustainable wheat production, yet how root exposure to allelopathic coumarins influences NUE remains poorly understood. This study tested the hypothesis that coumarin exerts dose-dependent and variety-specific effects on root growth and nitrate uptake kinetics in...
