Phytochrome destruction begins immediately following actinic irradiation of 4-day-old, dark-grown oat (Avena sativa L., cv. Garry) shoots grown in open containers. When grown in closed containers, otherwise identical oat shoots exhibit a delay of about 40 minutes between irradiation and the onset of destruction. This delay can be attributed to accumulation of ethylene by several criteria, including elimination of the delay by mercuric perchlorate. These data provide an explanation for otherwise contradictory observations concerning the presence of a delay prior to the onset of destruction.
光破坏作用在 4 天龄、黑暗中生长的燕麦（Avena sativa L.，cv. Garry）芽在开放容器中经光照射后立即开始。当在封闭容器中生长时，其它方面完全相同的燕麦芽在照射和破坏开始之间有大约 40 分钟的延迟。该延迟可以通过几个标准来归因于乙烯的积累，包括氯化汞消除延迟。这些数据为先前关于破坏开始前存在延迟的相互矛盾的观察结果提供了解释。
