Abstract: The experiment results indicated that there are significant differences among the ethylene release, the permeability of cell membrance and the intensity of respiration of tobacco leaves at different maturity. With the increasing of maturity of tobacco leaves, the release of ethylene, the permeability of cell membrance, and the intensity of respiration were increased. Also found that significant correlation existed between the release of ethylene in the leaves above paragraph and the permeability of cell membrance, and the intensity of respiration.

Key words: Maturity, Ethylene, Permeability of membrance, Intensity of respiration
