Effect of a short-term exposure to high CO2 on diurnal changes in acidity, starch content, and enzyme activities in O. alismoides. Plants acclimated to high light (HL) and low CO2 (LC) were exposed overnight to high CO2 (HC) and then kept at HLHC during the day. (A) Acidity, (B) starch content as glucose equivalents, (C) PEPC activity, (D) Rubisco activity, (E) the PEPC:Rubisco ratio, and (F) PPDK activity. Bars show the mean with 1 SD for three replicates. Data with different letters are significantly different within a specific treatment (P<0.05; one-way ANOVA).
