Self-incompatibility inCordyline australis(Asteliaceae)

Abstract

Controlled pollination among four individuals of Cordyline australis (cabbage tree, ti kouka) demonstrate that this species is self-incompatible, setting little or no seed when self-pollinated. Seed production per fruit in wild trees was less than half that observed following artificial pollination. Parthenocarpic fruit production is recorded in some wild populations.
