The average atmospheric concentration of CO 2 will probably double before the end of next century. Many of the consequences for plant growth can and should be determined now. In this review the effects of [CO 2 ] on a variety of plant processes are summarized: stomatal opening and closing; stomatal density; respiration; root morphogenesis; and flowering. The effects of growth under elevated [CO 2 ] on crop yield and seed composition are also discussed. Adverse effects on the composition of C 3 cereal grains are clearly indicated.
