A review of the function of ethylene in the senescence of cut flower

The senescence of cut flower is a highly regulated process which requires gene expression activation and protein synthesis, and it is associated with some biochemical changes, such as the increase of hydrolytic enzymes activity, degradation of macro-molecules, increase of respiratory activity and ethylene production. Ethylene production and its function are of important in the study of cut flower senescence. The current status of the study on biosynthesis, response and regulation of ethylene are reviewed.
