The Accumulation of Abscisic Acid in Plants During Wilting and Under Other Stress Conditions

Abstract

When excised wheat leaves are wilted and maintained in a wilted condition for a period of three to four hours there is a large increase in the “inhibitor β” content of the leaves. The amount of “inhibitor β” accumulating in the leaves was shown to be dependent on the length of the period in the wilted condition, the temperature of the wilted leaves and the degree of leaf-water deficit (Wright, 1969). Because of the inhibitor’s acidic nature and its RF in several solvent systems, ABA was suspected as being the substance concerned in the “inhibitor β” complex. This was later confirmed by optical rotatory dispersion (Wright and Hiron, 1969).
