Fig. 3 Percentage of undissociated form of salicylic acid (SA; a), 3-hydroxybenzoic acid (3-
OHBA; b) and 5-fluorosalicylic acid (5-FSA; c) in an octanol-water mixture and phloem
mobility as a function of pH. Predictions were computed with ACD Log D suite v 12.02 software.
Concentration factors in Ricinus phloem sap were determined using SA, 3-OHBA or 5-FSA
added to the incubation medium at 10 lM final concentration. The sap was collected during the
third and fourth hours of incubation. The concentration factor was the ratio [SA or 3-OHBA or 5-
FSA]sap/[SA or 3-OHBA or 5-FSA]medium. For box plots, 12 \ n \ 24. (From Rocher et al.
