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