Using a 2-h irradiation period at constant quantum irradiance, a complete action spectrum for inhibition of germination of lettuce seed has been obtained. Action maxima were near 470 and 720 nm, the latter being the most active wavelength. It was also shown, under conditions where light inhibition cannot occur, that phytochrome potentiation of germination is maximal at all wavelengths below 700 nm, including the highly active blue region. Evidence was presented for promotion of germination by a 2-h irradiation in the red which cannot be explained on the basis of conversion of phytochrome to the active form.
采用恒定量子辐照度 2 小时辐照期，获得了完全的生菜种子萌发抑制作用的作用光谱。作用最大值出现在 470nm 和 720nm 附近，后者是最活跃的波长。此外，在不可能发生光抑制的条件下，还表明，在所有低于 700nm 的波长下，包括高活性的蓝光区域，光敏素对萌发的促进作用达到最大。提出了在红光下照射 2 小时促进萌发的证据，这不能用光敏素转化为活性形式来解释。
