Minimum Ψl values of around –2.7MPa were reached in T1 treatment two days after the end of the flooding period, with no differences between rootstocks. In the T2 Búlida/P plants Ψl remained constant from day 4 to 6, then decreased to reach a minimum of –2.9 MPa four days after the end of the flooding period (Fig. 2 d). However, plants on RF rootstock showed a drastic decrease in Ψl (< –6MPa) (Fig. 2c), which caused the death of all the plants of this treatment.
