The effects of cyanide and 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) on photosynthesis and respiration of intact chlorophyllic moss (Funaria hygrometrica) spore was investigated. Thirty micromolar cyanide strongly inhibited dark respiration, was without effect on photosynthesis at high light intensities (above the saturation plateau values), and stimulated photosynthesis at low light intensities (below the saturation plateau values). Three hundred nanomolar DCMU inhibited the photosynthesis and was without effect, even under light conditions, on the dark respiration. It seems likely, therefore, that in the chlorophyllic moss spore the cytochrome oxidase pathway is not functioning under high light intensities unless the photosynthesis is inhibited by DCMU.
研究了氰化物和 3-(3,4-二氯苯基)-1,1-二甲基脲（DCMU）对完整叶绿素藓（Funaria hygrometrica）孢子光合作用和呼吸作用的影响。30 微摩尔氰化物强烈抑制暗呼吸，对高光强（超过饱和平台值）下的光合作用没有影响，并刺激低光强（低于饱和平台值）下的光合作用。300 纳摩尔 DCMU 抑制光合作用，即使在光照条件下，对暗呼吸也没有影响。因此，在叶绿素藓孢子中，细胞色素氧化酶途径在高光强下不起作用，除非光合作用被 DCMU 抑制。
