Inhibitor content of phloem and xylem sap obtained from willow (Salix viminalis L.) entering dormancy

M R Bowen et al. Planta. 1968 Mar.

Abstract

It is shown that there is one growth inhibitor in the phloem sap and two in the xylem sap of willow (S. viminalis L.). The concentration of the inhibitor in the phloem sap, (+)-abscisic acid, increases as the plants enter dormancy. This is also shown for (+)-abscisic acid in the xylem sap, but the concentration of the second inhibitor decreases in a reciprocal manner.
