In vitro plant regeneration in lateral bud explants of Cryptanthus bromelioides Var. Tricolor M. B. Foster
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.
