Fig. 2From: ABA-mediated responses to water deficit separate grapevine genotypes by their genetic backgroundConcentration in ABA, PA and DPA in shoot and root xylem sap (ng/ml). Mean and standard deviation of abscisic acid (ABA; a & b), phaseic acid (PA; c & d) and dihydrophaseic (DPA; e & f) for non-stressed (water potential > -0.2 MPa; a, c & e) and water-stressed (water potential < -0.8 Mpa; b, d & f) plants. Values among genotypes with the same letter are not statistically different (Tukey-HSD) (n = 1–10)Back to article page
