Trapella sinensis seedlings were examined to determine whether the effect of growth regulators such as gibberellin (GA 3 ), kinetin and the extract of Chlorella cells on chlorophyll formation, photosynthetic activity and cytochrome oxidase activity depend upon the developmental stage. Each addition promoted the growth on both the basis of dry weight and of fresh weight. Among these regulators, only Chlorella extract promoted growth as a result of an activated rate of photosynthesis through increased chlorophyll formation. There also was an increased respiratory rate through increased cytochrome oxidase activity.
