Abstract
Rates of photosynthesis of 3 wild Arachis species and 5 groundnut cultivars were measured in air in which the CO2 concentration ranged from 0 to 6000 ppm. Activity increased linearly with CO2 concentration, most rapidly for cv. Florunner and least rapidly for A. pintoi. Photorespiration, measured by CO2 evolution into CO2-free air, averaged 4 mg CO2/dm2 and did not differ between genotypes. Dark respiration was higher among wild than among the cultivated genotypes. Leaf diffusion resistance remained low from 0900 to 1500 h, then increased rapidly to 2200 h. Individual changes in diffusion resistance were not closely related to photosynthetic rate, and this rate was not closely related to leaf chlorophyll content, stomatal frequency, leaf N content or specific leaf weight.
