Abstract	The synthesis of a deuterated analogue of the plant hormone S-(+)-abscisic acid (ABA), S-(+)-[7′, 7′, 7′, 8′, 8′, 8′, 9′, 9′, 9′]-nonadeuteroabscisic acid [(+)-d₉-ABA], is described. The biological activity of (+)-d₉-ABA was compared to that of (+)-ABA in two assays. Analogous to the metabolism of (+)-ABA to (−)-phaseic acid (PA) by maize (Zea mays L. cv Black Mexican Sweet) cell suspension cultures, (+)-d₉-ABA was oxidized but at a slower rate to d₈-PA at 25°. At low concentrations the deuterated analogue was a more effective inhibitor of cress seed (Lepidium sativum L.) germination than the natural hormone.
