abstract = {The objective of this study was to determine whether leaf color change in rice plants predicts ammonia (NH3) volatilization during the late grain-filling period. In a pot study of indica and indica–japonica hybrid cultivars, the leaf color-changing rate was highly significantly positively correlated with NH3 volatilization during the grain-filling stage. Cultivars with fast leaf color-changing had higher NH3 volatilization loss due to their higher apoplastic NH4+ concentration and NH3 compensation point, along with lower glutamine synthetase (GS) activity. N application, although it delayed leaf color change, led to increased NH3 volatilization. Selecting cultivars with slow leaf color-changing characteristics and managing fertilization to delay the leaf color change process could reduce N gas loss and increase N use efficiency.}
