A new instrument for the recording of leaf movement rhythm is described. Coleus blumei x C. frederici, a short day plant, exhibits a circadian rhythm of leaf movement. The period length of the free running rhythm is shortest in continuous darkness and is increased with an increase in the light intensity. The amplitude of the rhythm tends to damp in continuous bright light.
描述了一种用于记录叶片运动节律的新仪器。短日植物彩叶草和弗雷德里克氏彩叶草表现出叶片运动的昼夜节律。自由运行节律的周期长度在连续黑暗中最短,并随着光强度的增加而增加。在持续明亮的光线下,节律的幅度趋于衰减。
