Functions of Naturally Produced Ethylene in Abscission, Dehiscence And Seed Germination
It is well established that plants produce ethylene as a natural emanation; however, whether ethylene has a functional role in plant growth has often been questioned. Studies of auxin-induced ethylene synthesis and ethylene-mediated reduction of auxin transport capacity (Hall and Morgan, 1963; Morgan, Beyer and Gausman, 1968) have contributed to the recognition of auxin-ethylene interactions as an important area of plant hormone physiology. During recent months these interests have led to studies of some related aspects of ethylene physiology in two plant systems, the role of native ethylene in abscission phenomena in the cotton plant and its involvement in peanut seed germination.
