Photoacoustic measurements of photosynthetic oxygen evolution and its enhancement by addition of background far-red light (Emerson enhancement) were made on both intact and inhibited or stressed leaves. The extent of enhancement increased with the dehydration treatment and decreased with a mild heat treatment or with the addition of DCMU. It nevertheless persisted even at a very high degree of inhibition - a result which indicates high population ratio of single pairs of combined photosystem II and photosystem I units, functional in whole chain electron transport. This implies a restriction on the separation between photosystems I and II, in contrast to existing concepts.
对完整叶片、抑制或胁迫叶片进行了光声测量，以测量光合作用氧气产生及其增强（爱默生增强）。增强程度随脱水处理增加而增加，随温和热处理或 DCMU 添加而降低。然而，即使在非常高的抑制程度下，它仍然存在 - 这一结果表明，在整个电子传递链中功能的结合光系统 II 和光系统 I 单位的单对组合的高群体比例。这表明在光系统 I 和 II 之间的分离受到限制，这与现有概念相反。
