Irradiation with red light leads to the formation of an unstable, undergoing gradual destruction, physiologically active PFR form of phytochrome in the coleoptiles of oat seedlings. Growth substances: IAA, GA3, kinetin, ABA, ethrel as well acetylcholine do not influence the nature and rate of phytochrome dark transformation. Inhibitors of energy-producing processes such as KCN, 2,4-DNP, DCCD and antimycin A inhibit the process of dark destruction of the PFR form of phytochrome
