Figure 6 in Photosynthetic metabolism and antioxidant in Ormosia arborea are modulated by abscisic acid under water deficit?

Figure 6. Enzymatic activity of superoxide dismutase in leaves (SOD Leaves) (A) and roots (SOD roots) (B) of Ormosia arborea seedlings irrigated (I and I 10 µM ABA) and submitted to water deficit conditions (SI and SI 10 µM ABA) in the different evaluation periods: zero time (T0), first null photosynthesis (1st P0), second null photosynthesis (2nd P0), recovery (REC) and final evaluation (END). Upper case letters differ between trial times and lowercase letters between treatments.
