The Japonica cultivar ‘Janganbyeo’ was cultivated and about half of paddy field was totally lodged at 30 days afterheading. Both lodged paddy and unlodged paddy were harvested at intervals. The lodged paddy and brown rice did not showany signs of viviparity until the 4th day of lodging. The activities of α-amylase, diastase, and lipase of lodged paddy andbrown rice began to increase on the 2nd day of lodging and then increased slowly afterwards. The activities of protease andphytase of lodged paddy and brown rice reached the maximum values on the 2nd day and then decreased until the final day oflodging. In contrast, unlodged paddy and brown rice showed relatively small increase in viviparity and in activities of α-amylase, diastase, protease, lipase, and phytase. Especially, activities of diastase and lipase were observed even in unlodgedpaddy and brown rice.
