Abstract

This study was designed to determine the effects of red and far red irradiation on ATP metabolism in etiolated bean buds (Phaseolus vulgaris L. var. Red Kidney). Compared to dark controls, red irradiated buds show an initial decline in ATP content at 15 seconds following a 5-minute irradiation. ATP content then rapidly rises to a peak at 1 minute, and then slowly returns to the baseline. The 1-minute promotion of ATP content is red/far red reversible. Acetylcholine does not appear to mimic red light in this system; it causes a marked decrease in ATP content.

摘要

本研究旨在确定红光和远红光照射对黄化菜豆芽(Phaseolus vulgaris L. var. Red Kidney)ATP 代谢的影响。与黑暗对照相比,红光照射的芽在照射后 15 秒内 ATP 含量最初下降。然后,ATP 含量迅速上升到 1 分钟时的峰值,然后缓慢恢复到基线。1 分钟时 ATP 含量的增加是红光/远红光可逆的。在这个系统中,乙酰胆碱似乎不能模拟红光;它会导致 ATP 含量明显下降。
