A short period (15-30 min) at 30° C promotes germination of seeds of Lactuca sativa L. cv. Repolhuda in darkness. Far-red light reverses this stimulation, and the escape curves for phytochrome and high-temperature action are quite similar, indicating that the two factors act at a common point in the chain of events leading to germination. It is suggested that high temperature acts by decreasing the threshold of the active, far-red absorbing, form of phytochrome (Pfr) needed to promote germination.
在 30°C 的短时间（15-30 分钟）促进生菜种子 cv. Repolhuda 在黑暗中发芽。远红光会逆转这种刺激，而光敏色素和高温作用的逃逸曲线非常相似，表明这两个因素在导致发芽的事件链中作用于共同的点。因此，高温可能通过降低促进发芽所需的活跃的、远红光吸收形式的光敏色素（Pfr）的阈值来发挥作用。
