Fig. 5. — Effect of a short-term exposure to low light on diurnal changes in acidity, starch content, and enzyme activities in O. alismoides. Plants acclimated to high light (HL) and low CO₂ (LC) were kept at low CO₂ and exposed to low light (LLLC). At the end of the photoperiod, plants were treated overnight at high CO₂ (HC) or kept at low CO₂, and leaves were harvested at the end of the scotoperiod. (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. At the end of the scotoperiod (07.30 h), different letters designate treatments whose results are significantly different (P<0.05; one-way ANOVA).
