When irradiated for a period of 48 hours with light of restricted wave-lengths in the red and far-red regions, maximum anthocyanin content in hypocotyls was found at 730 nm; in cotyledons the yield at 716 was almost equal to that at 730 nm.In hypocotyls the effectiveness of 703, 716 and 760 nm light was much increased if plants were transferred to red light after 6 hours. The intermediate wave-length band centred at 703 nm was ineffective when given alone but led to a high yield if followed by red light. When given before far-red light (standard far-red field), 6 hours at 703 nm reduced anthocyanin yield in the same way as red light; when given after 6 hours of far-red, however, 703 nm light did not act like red light to sustain a high rate of anthocyanin synthesis.It is concluded that two reactions are involved in the photocontrol of anthocyanin formation in turnip seedlings.
当用限制在红光和远红光区域的特定波长的光照射 48 小时时，在 730nm 处发现下胚轴中最大的花色素苷含量；在子叶中，716nm 的产率几乎与 730nm 处相同。如果在 6 小时后将植物转移到红光下，703nm、716nm 和 760nm 光的有效性大大增加。当单独给予中间波长带（以 703nm 为中心）时，它没有效果，但如果紧随其后是红光，它会产生很高的产量。当给予远红光（标准远红光场）之前 6 小时的 703nm 光时，以与红光相同的方式降低花色素苷的产量；然而，当给予远红光 6 小时后，703nm 光不会像红光一样起作用，以维持高花色素苷合成率。因此，可以得出结论，在萝卜幼苗中花青素形成的光控涉及两个反应。
