Abstract
Abstract Bending stree resulted in an increase in the ethylene concentration in the internal atmosphere of apple stem ( Malus domestica Borkh. cv. Winesap). reaching a maximum at about 2 days after bending. The rise in ethylene content was followed by a depression of growth at about 14–21 days. Ethylene content returned to control levels after about 3 weeks. Application of a past naphthaleneacetic acit caused a similar increase in ethylene levels, and the application of ethephon pastes brought about an inhibition of elongation growth. Whereas stress treatment resulted in an inhibition of growth in stem diameter as well as elongation of growth in stem diameter as well as elongation, the ethephon applications resulted in a stimulation of growth in diameter. It is suggested that ethylene may be involved in the growth responses to mechanical stress.
