Carbondioxide compensation concentration in pea and sorghum as influenced by growth stage, nitrogen and moisture stress

Carbondioxide compensation concentration (CO₂CC) is inluenced to a greater extent by growth stage in pea and sorghum. Moisture stress and nitrogen fertilization increased CO₂CC. Even sorghum, which is a C₄ plant, showed CO₂CC in the same range as that of a C₂ plant towards maturity and also when moisture stress was given.
