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.

本研究的目的是阐明对气候变暖耐受的生理机制，并获得遗传信息，从而开发高耐受性的新品种。长期变暖处理造成的损害与活性氧（ROS）产生引起的光合作用抑制有关。耐性品种的叶子较厚，这可能与 ROS 产生的抑制有关。获得了有助于耐性品种开发的遗传信息。
