Influence of Auxin and Cytokinin on Callus Induction of Mulberry

Abstract

Present experimental article explained the potentialities of explants of ten mulberry varieties (Morus sp. var. Kajli, Kajli-OP, S1, Berhampore local, S1635, Bishnupur local, Bogura local, S2028, Tr10, BC259 and S1) on Gamborg’s B5 media fortified with  different combinations of Naphthalele acetic acid (NAA) and Kinetin as auxin and cytokinin respectively towards development of callus. The ratio of auxin and cytokinin ranges from 1 to 7. The combination among endogenous with exogenous auxin as well as cytokinin levels indicated pivotal role in differential induction of callus in the varieties tested. First four and the last varieties were found to be early respondents, while the others were induced for callusing at a later stage. The early respondents favoured comparatively low dose ration of auxin to cytokinin.
