Figure 5

Comparative quantification of ABA precursors, ABA and ABA-GE using GC-MS and RIA techniques for free ABA (circles) ABA ex Adduct I (triangles), ABA ex Adduct II (inverted triangles) or ABA ex ABA-GE (squares) for xylem sap collected from the roots (filled symbols) or the petiole stub of otherwise intact tomato plants (hollow symbols). Each point is a separate xylem sap sample, with the solid line representing the 1:1 relationship.
