Abstract
Leaf, stem, hypocotyl, cotyledon, root, shoot tip and embryo explants of Capsicum annuum L. cv. mathania were cultured on Murashige and Skoog (MS) medium supplemented with 6-benzylaminopurine (BAP) or kinetin (Kin) alone or in combination with 3-indoleacetic acid (IAA), 3-indolebutyric acid (IBA), α-naphthaleneacetic acid (NAA) or 2,4-dichlorophenoxyacetic acid (2,4-D). BAP (5.0 mgl−1) in the medium was found to be the best growth regulator for shoot bud differentiation. Shoot buds cultured on 5.0 mgl−1 BAP increased in number but did not elongate. For obtaining complete plantlets, shoot buds were placed on a medium with IBA or NAA (0.1 mgl−1). Histological evidence revealed direct differentiation of buds from cotyledons. Regenerated plants were normal diploids. Unorganized callus could not be induced to differentiate shoot buds.
