Research Abstract

This study was conducted to clarify physiological mechanisms of tolerance to climate warming and to obtain genetic information leading to the development of new cultivars with high tolerance. The damage under prolonged warming treatment was related to depression of photosynthesis caused by generation of reactive oxygen species (ROS). The tolerant cultivars had thicker leaves that could be related to depression of the ROS generation. Genetic information, which could contribute the development of tolerant cultivars, was obtained.
