Figure 4 in Photosynthetic metabolism and antioxidant in Ormosia arborea are modulated by abscisic acid under water deficit?

Figure 4. Activity of the catalase enzyme in leaf (A) and root (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 (1 st P0), second null photosynthesis (2nd P0), recovery (REC) and final evaluation (END). Upper case letters differ between trial times and lowercase letters between treatments.
