Abstract

Lateral buds of Cryptanthus bromelioides var. tricolor variegated ornamental bromeliad, were cultured on Murashige and Skoog's basal medium (MS) supplemented with napthaleneacetic acid, indolebutyric acid, and kinetin, each at 2 mg/l. The basal part of the cultured buds proliferated and produced adventitious shoots. The shoots developed into plants of three different phenotypes: (a) entirely green, (b) striated (green and yellowish-white) and (c) yellowish-white. Rooting could be induced in (a) and (b) types but successful transplantation was possible only with green plants some of which underwent color changes after establishment in soil.
