Leaf transpiration rate (A) and osmotic root hydraulic conductance (L; B) of common bean plants subjected to drought for 4 d (4D) and 1 d after re-watering (4D + 1), and the corresponding control plants (C4D and C4D+1), or of plants leaf sprayed 24 h earlier with 100 μm ABA or 200 μm MTX, and unsprayed control plants (CAM). Bars represent the mean ± s.e. (n = 20). Bars with the same letter indicate that there are no significant differences (P > 0.05) among them after ANOVA and Fisher l.s.d. tests.
