促进敏感红豆草原丝体伸长的作用光谱在400-420、580-600和640-660 nm处有峰。在饱和光剂量下，最大的生长增量是由黄色和远红光产生的。黄光和远红辐射诱导的伸长作用在老丝和幼丝中持续存在，而红光促进作用仅在幼丝中发现。黄光引起的生长促进作用被红光部分逆转，下降到仅由红色照射产生的生长水平。根的伸长受可逆的红光和远红光控制，而黄光不活跃。提出并讨论了一个模型，在该模型中，细丝的光敏伸长是由三个不同的光感受器的存在来解释的：光敏色素；一种吸收黄光的色素。P580和一种吸收蓝光的颜料P420。
The action spectrum for promotion of elongation of protonemata of Onoclea sensibilis has peaks at 400–420, 580–600 and 640–660 nm. The largest growth increments at saturating light doses are produced by yellow and far-red light. Elongation induced by yellow and far-red irradiation persists in old as well as young filaments, while red-light promotion is found only in young filaments. The growth promotion caused by yellow light is partially reversed by red light down to the level of growth produced by red irradiation alone. Elongation of rhizoids is under reversible red, far-red control, while yellow light is inactive. A model is proposed and discussed in which the light-sensitive elongation of filaments is accounted for by the presence of three distinct photoreceptors: phytochrome; a pigment absorbing yellow light. P580; and a pigment absorbing blue light, P420.
