Table 2 Mean values and standard error of water potentials inducing 50% loss of conductivity (P50) estimated with a 100-cm rotor (P50 CAVI 1000) and with associated reference technique (P50 reference). n corresponds to the number of replicates for each mean value, and d corresponds to the average sample diameter
