Data are averages of 6, 9, and 3 determinations per rootstock, water quality and rootstock per water quality respectively. For each parameter, letters denote significant differences between treatments at p < 0.05 (Duncan test). The statistical significance effect of the rootstock (R), water quality (WQ) and their interaction are also indicated by means of the p-values from the ANOVAs. Significance of effects in bold denotes statistically significant differences at p < 0.05.
