Abstract

Both high and low C02 compensation concentrations were found in the plant genera-Panicum, Cyperus, and Euphorbia. Within each genus, however, high and low compensations were found in different subgenera. Thus, they may not be genetically closely related. No significant differences in CO2 compensation were found among 100 genetic lines of Triticum aestivum L. or among 20 lines of Hordeum vulgare L.
