The development of two types of stomatal transpiration, one induced by light (light-induced stomatal transpiration) and the other induced by CO_2-free air in the dark (CO_2-sensitive stomatal transpiration), in greening leaves of wheat ( Triticum aestivum L.) was studied in respect to the development of CO_2 uptake and chlorophyll formation. Light-induced stomatal transpiration was not observed at all in etiolated leaves and was generated after 3 hr of illumination for greening, when the activity of CO_2 uptake was generated. CO_2-sensitive stomatal transpiration was low in etiolated leaves and started to increase at the same time during greening as the start of CO_2 uptake. The activities of both light-induced and CO_2-sensitive stomatal transpiration increased as the activity of CO_2 uptake and the chlorophyll content increased. Pre-illumination of etiolated leaves for 1 min followed by 4 hr of dark incubation eliminated the lag for the development of the two types of stomatal transpiration and CO_2 uptake.
