Climacteric rise, ethylene production, peroxidase activity and its isozyme and their interrelationships during the ripening of tomato fruits have been studied. It was found' that there was parallelism between ethylene production and climacteric rise. The climacteric rise of tomato fruits was hastened by ethylene applied at the mature green stage. The ethylene production was inhibited by low oxygen and high carbon dioxide partial pressure. The peroxidase activity in the tomato fruits appeared to be different at three stages, higher in the half red fruits and lower in both green mature and fully red fruits. This activity was increased by ethylene and decreased by lower partial pres- sure of oxygen. The peroxidase isozymes sppeared also different at different stages of ripening. There were 4 bands in young fruits, 3 in green mature fruits, 5 in half red fruits and 3 in fully red fruits. After the application of ethylene to the tomato fruits, there appear one new band of peroxidase isozyme.
