Fluence-rate response curves for wavelengths from 640 nm to 730 nm were constructed for the day-extension promotion of flowering in green, light-grown, wheat (Triticum aestivum L., cv. Alexandria), a long-day plant. The resultant action spectrum had action maxima at 660 nm and 716 nm and resembles spectra for the high-irradiance reaction (HIR) seen in etiolated plants. Because, the HIR is thought to be controlled by type I pytochrome (that which is most abundant in etiolated tissue) our results indicate the involvement of type I phytochrome in the photomorphogenesis of a light-grown, green plant.
我们构建了 640nm 至 730nm 波长的光通量响应曲线，以促进长日植物、绿色、光生长的小麦（Triticum aestivum L.，cv. Alexandria）开花。所得作用光谱在 660nm 和 716nm 处具有作用最大值，类似于在黄化植物中看到的高光强反应（HIR）的光谱。由于 HIR 被认为受 I 型光敏色素（在黄化组织中最丰富）控制，我们的结果表明 I 型光敏色素参与了光生长的绿色植物的光形态发生。
