Table 1.
Mean values (±standard error) of morphological and hydraulic characteristics in the three olive cultivars. VD: vessel density; dm: mean vessel diameter; Av: ratio of total vessel area to total xylem area; DH: hydraulic diameter; Kst: theoretical hydraulic conductivity. Different letters indicate statistical significance (p-value < 0.05) according to Tukey’s multiple post hoc test.
