A transient in chlorophyll fluorescence, which is associated with a transient in 9-aminoacridine fluorescence and a perturbation in the rate of oxygen evolution, has been observed in intact spinach chloroplasts. The results indicate that changes in the redox state of Q are, at least partially, responsible for the transient in chlorophyll fluorescence. The size of the transient is highly dependent upon the concentration of inorganic phosphate and upon the pH of the medium. The properties of the transient are consistent with the suggestion that it reflects changes in the levels of stromal intermediates during induction.
在完整的菠菜叶绿体中观察到叶绿素荧光的瞬时变化，该变化与 9-氨基吖啶荧光的瞬时变化和氧释放速率的扰动有关。结果表明，Q 的氧化还原状态的变化至少部分地导致了叶绿素荧光的瞬时变化。瞬变的大小高度依赖于无机磷酸盐的浓度和介质的 pH 值。瞬变的性质与以下建议一致，即它反映了诱导过程中基质中间产物水平的变化。
