Figure 1. Variation of pre-dawn stem xylem water potential (Ψpd) of the average of four Eucalyptus globulus genotypes during drought hardening time course. Three drought hardening treatments were applied during 54 days (May-June 2004), consisting of two cycles of watering restriction until certain stem water potential were reached (-0.2, -1.8 and -2.6 MPa). After the target water potential was reached, plants were thoroughly watered until substrate saturation. Error bars represent ± 1 SE, n = 80.
