SUMMARY. Measurements of the rate of oxygen uptake in a number of blue-green algae and diatoms were carried out under both field and laboratory conditions to determine the effects of light on such rates. The light history of algal cells was an important controlling factor of oxygen uptake. When measured in the light, with dichlorophenyl-dimethylurea (DCMU), oxygen uptake was sometimes different from uptake measured in the dark. The results cast some doubt on the validity of the light and dark bottle method for determining primary productivity. It is suggested that oxygen uptake measurements should be made in the presence of DCMU.
