英文摘要Crops developed under elevated carbon dioxide (eCO(2)) exhibit enhanced leaf photosynthesis under steady states. However, little is known about the effect of eCO(2) on dynamic photosynthesis and the relative contribution of the short-term (substrate) and long-term (acclimation) effects of eCO(2). We grew an Oryza sativa japonica cultivar and a Triticum aestivum cultivar under 400 mu mol CO2 mol(-1) air (ambient, A) and 600 mu mol CO2 mol(-1) air (elevated, E). Regardless of growth [CO2], the photosynthetic responses to the sudden increase and decrease in light intensity were characterized under 400 (a) or 600 mu mol CO2 mol(-1) air (e). The Aa(1), Ae(2), Ea(3), and Ee(4) treatments were employed to quantify the acclimation effect (Ae vs. Ee and Aa vs. Ea) and substrate effect (Aa vs. Ae and Ea vs. Ee). In comparison with the Aa treatment, both the steady-state photosynthetic rate (P-N) and induction state (IS) were higher under the Ae and Ee treatments but lower under the Ea treatment in both species. However, IS reached at the 60 sec after the increase in light intensity, the time required for photosynthetic induction, and induction efficiency under Ae and Ee treatment did not differ significantly from those under Aa treatment. The substrate effect increased the accumulative carbon gain (ACG) during photosynthetic induction by 45.5% in rice and by 39.3% in wheat, whereas the acclimation effect decreased the ACG by 18.3% in rice but increased it by 7.5% in wheat. Thus, eCO(2), either during growth or at measurement, enhances the dynamic photosynthetic carbon gain in both crop species. This indicates that photosynthetic carbon loss due to an induction limitation may be reduced in the future, under a high-CO2 world.
