Physiological Determinants of High Nitrogen-Use Efficiency in Waxy Sorghum: Integrated Analysis of Biomass Production, Nitrogen Assimilation, and Antioxidant Metabolism
Sorghum [Sorghum bicolor (L.) Moench] production faces persistent challenges from low nitrogen-use efficiency (NUE) under the intensive cultivation systems of Southwest China. To elucidate the physiological determinants of genotypic variation in NUE, a two-site field experiment was conducted in Guiyang and Anshun using...
