Abstract
Changes in root exudates after initial heading stage were studied in indica-japonica hybrid rice cv. II you2070, II you419 and their restorer lines 2070, Zhong419. Root activity of the hybrids was higher than their restorer lines, especially from initial heading stage to milk ripening stage. However, the amount of root exudate rapidly decreased after milk ripening stage. These changes were consistent with the photosynthesis rate and chlorophyll content of leaves at different levels and with green leaf area.
