Effect of IAA (10(-10)-10(-3) M) on photophosphorylation, NADP reduction and the oxygen exchange is investigated. It is shown that low concentrations of IAA (10(-10)-10(-7) M) increase the photophosphorylation reaction and the flow of electrones to NADP under the phosphorylation conditions in the chloroplasts, and their effect on the O2 exchange is not the same in different types of photophosphorylation. It is supposed that the effect of IAA on the photophosphorylation is connected with H292 metabolism in chloroplasts and with catalase and peroxidase functions.
研究了吲哚乙酸（IAA，10⁻¹⁰ - 10⁻³ M）对光合磷酸化、NADP还原及氧交换的影响。结果表明，低浓度的IAA（10⁻¹⁰ - 10⁻⁷ M）在叶绿体磷酸化条件下可增强光合磷酸化反应以及电子向NADP的流动，并且其对O₂交换的影响在不同类型的光合磷酸化中有所不同。推测IAA对光合磷酸化的影响与叶绿体中的H₂O₂代谢以及过氧化氢酶和过氧化物酶的功能有关。
