The present paper will therefore focus on those aspects of crop
physiology under e[CO2] that can contribute to the adaptation of
crops and cropping practices to a high CO2 environment. In particular,
three key areas are likely to play a major role in adaptation. Their
physiological foundation will therefore be examined more closely:
(1) the selection or production of new crop cultivars with optimised
performance under e[CO2], (2) adaptation of agronomic practices,
particularly nutrient management, to changing plant metabolic
