Quality maintenance in postharvest horticultural crops by stress treatments and development of novel storage methods

点击翻译按钮获取中文摘要

Effects of stress treatments such as heat, ethanol, UV-B and hydrogen peroxide application on quality maintenance in postharvest horticultural crops were determined by physiological, biochemical and molecular biological analyses. Appropriate conditions of each stress treatment for keeping quality during storage were also studied. These findings obtained suggest that stress treatments make it possible to maintain postharvest storage quality of horticultural crops due to the generation of active oxygen species and the activation of scavenging system, the control of ethylene production, and the maintenance of chemical components. Furthermore, stress treatments seem to lead to novel storage and transport technologies.
