Method Many of the photon-yield and fluorescence determinations on plants grown in their native habitats were made in North Queensland, Australia, during the period from May through October 1983. Rates of photosynthetic 02 exchange were measured at 25.0degrees C and CO2 saturation with a system incorporating a leaf-disc electrode (Model LD-2 Hansatech, Kings Lynn, Norfolk, UK) designed by Delieu and Walker (1981, 1983), and a fan-cooled quartz-lamp housing, designed and built in this laboratory.
