Figure 9From: Antagonistic actions of boron against inhibitory effects of aluminum toxicity on growth, CO2 assimilation, ribulose-1,5-bisphosphate carboxylase/oxygenase, and photosynthetic electron transport probed by the JIP-test, of Citrus grandisseedlingsInitial Rubisco activity (A, D), maximum amplitude of IP phase (B, E) and PI tot,abs (C, F) in relation to leaves CO 2 assimilation and shoot DW in Citrus grandis seedlings. All the values were expressed relative to the sample treated with 2.5 μM B + 0 mM Al set as 1. Maximum amplitude of IP phase = (Fm - Fo)/(FI - Fo) - 1.Back to article page
