Abstract
After inhibition of Nemophila insignis seeds by far-red (FR) light, a short exposure to blue (Bl) will not induce germination again but stimulation by red (R), with reversion by FR, can be observed. Germination is inhibited by long exposures to Bl (maxima at 455 and 475 nm). These radiations are absorbed either directly by phytochrome or through intermediary pigments such as flavoproteins.
摘要
远红（FR）光抑制勿忘我种子萌发后，短暂暴露于蓝光（Bl）下种子不会再次萌发，但可观察到红光（R）刺激和 FR 逆转的现象。长波段的 Bl（最大吸收在 455 和 475nm）会抑制萌发。这些辐射要么直接被光敏色素吸收，要么通过中间色素如黄素蛋白吸收。
