Popis: Rising atmospheric carbon dioxide concentration [CO 2 ] is expected to cause increases in crop growth and yield. The objective of this study was to investigate effects of subambient, as well as superambient, [CO 2 ] on soybean [Glycine max (L.) Merr.] dry matter production and allocation for two reasons : to assess response of plants to prehistoric as well as future expected CO 2 levels and to increase confidence in [CO 2 ] response curves by imposing a wide range of [CO 2 ] treatments. Soybean was grown in outdoor, sunlit, controlled-environment chambers at CO 2 levels of 160, 220, 280, 330, 660, and 990 μmol (CO 2 ) mol −1 (air) (...)
