Which of the following is the incorrect prediction about ABA translocation in vascular tissue by both the xylem and the phloem?

#Unit 6. System Physiology – Plant

ABA synthesized in the roots can also be transported to the shoot via the xylem
the concentration of ABA in the xylem sap of well-watered sunflower plants is between 1.0 and 15.0 nM, while in in waterstressed plants increases to as much as 3000 nM (3.0 µM )
Concentration of 15.0 nM ABA in the apoplast is sufficient to close stomata, all of the ABA in the xylem stream reaches the guard cells
ABA also is transported in a conjugated form, then released by hydrolysis in leaves.
