AB - Abstract Wheat, Triticwn aestivum L., the winter cultivars Hobbit and Cappelle-Desprez, and the spring cultivars Sicco and KJeiber, were grown in normal air or air enriched with CO2 either outdoors in a glass-roofed cage or in controlled environment rooms. In neither the winter nor the spring wheat was growth increased due to enrichment with CO2 before anthesis. Enrichment of the two winter wheat cultivars increased shoot dry weight significantly at 15 d after anthesis but produced no significant increase in grain yield. With the spring cultivars there was a significant increase in shoot dry weight by 18 d after anthesis and the grain yield was also larger due to an increase in grain size. Shoot weight increased because the stems were larger, and there was a diversion of assimilate from grain growth to late tiller production. Root tissue comprised less than 20% of the total dry matter at anthesis (for all cultivars); effects of CO2 enrichment on root growth appeared to be less important than effects on shoot and ear growth. Growth and yield responses to CO2 enrichment were observed (for the spring cultivars) at irradiances of both 250 and 635 μE m−2 s−1, but the effects were greater at the lower irradiance.
