Abstract: The effects of sink size regulation on nitrogen metabolism of different position leaves in rice were studied by removing panicles or spikelets. With panicles or spikelets removed, protein synthesis in full-grown leaves was renewed vigorously, resulting in increased protein nitrogen content, especial
