The reducing agents, potassium ferrocyanide, beta-mercaptoethylamine, cysteine, reduced DPN, ferrous sulfate, methyl viologen and ascorbic acid caused the expansion in darkness of disks of primary leaf tissue cut from dark-grown bean plants. The reducing agents interacted synergistically with low irradiances of red radiation and additively with high irradiance of red light. Exposure of disks treated with reducing agents to far red light repressed disk expansion and the decay in sensitivity to far red radiation showed the same time relations as sequential exposure to red and far red radiation.The oxidizing agents, 1,4-naphthoquinone, ferric sulfate, hydrogen peroxide, t-butyl hydroperoxide, cystine, and potassium ferricyanide repressed the expansion of leaf disks initiated by exposure to red radiation. The oxidizing agents interacted synergistically with low irradiances of far red light and additively with irradiances of far red light.
还原剂（亚铁氰化钾、β-巯基乙胺、半胱氨酸、还原型二磷酸吡啶核苷酸、硫酸亚铁、甲紫精、抗坏血酸）可引起暗培养的菜豆叶片组织切圆片在黑暗中扩展。还原剂与低辐照度的红光协同作用，并与高辐照度的红光相加作用。用还原剂处理的圆盘暴露在远红光下，抑制了圆盘的扩展，而且对远红光的敏感性下降，其时间关系与顺序暴露在红光和远红光下的时间关系相同。氧化剂（1,4-萘醌、硫酸铁、过氧化氢、叔丁基过氧化氢、胱氨酸、铁氰化钾）抑制由红光照射引发的叶片圆盘的扩展。氧化剂与低辐照度的远红光协同作用，并与远红光的辐照度相加作用。
