Fig. 5.
Seasonal averages of mesophyll conductance (gm, mol m−2 s−1, A), the maximum carboxylation rate by Rubisco (Vcmax, µmol m−2 s−1 B), and the regeneration of ribulose-1,5-bisphosphate controlled by the electron transport rate (Jmax, µmol m−2 s−1 C) at 28 °C from eight cultivars of cassava grown at ambient (AMB CO2) and elevated [CO2] (ELE CO2). Values are means ±SE (n=4). Treatments with different letters represent significant differences (P<0.1); underlining is used to help differentiate groups of letters.
