Pea plants (Pisum sativum L. var. Alaska) subjected to low temperature (5 degrees ) in the light acquired resistance against chilling injury.Unhardened plants maintained high NADP and low NADPH levels during illumination at 25 degrees but hardened plants had low NADP and high NADPH levels in the light. When the unhardened plants were transferred to the dark room at 25 degrees , their NADPH levels decreased immediately. On the other hand, hardened plants maintained a high NADPH level for a few hours even in the dark.
豌豆植株(Pisum sativum L. var. Alaska)在光照下受到低温(5 摄氏度)处理后获得了抗冷伤害的能力。未硬化的植株在 25 摄氏度光照下保持高 NADP 和低 NADPH 水平,但硬化的植株在光照下具有低 NADP 和高 NADPH 水平。当未硬化的植株在 25 摄氏度下转移到暗室时,它们的 NADPH 水平立即下降。另一方面,硬化的植株即使在黑暗中也能维持几个小时的高 NADPH 水平。
