The influence of auxin and cytokinin combinations in plant regeneration of cocoyam (Xanthosoma sagittifolium)
1990
McDonald, F.D.
The standard Murashige and Skoog (1962) culture medium was proven effective for initiation of meristem in cultures of Xanthosoma sagittifolium (cocoyam; tannia) Rabess cv. but was found not to be so useful for plantlet regeneration. However, when cultures at 6-8 weeks old were transferred to an amended basal medium (with the exclusion of benzylaminopurine (BAP)) calli formation was high along with organogenesis resulting in extensive shoot and root development. Plantlet regeneration from meristems was achieved within 16-20 weeks. There was no significant variation in plant morphology of plantlets regenerated using this two-step production system.
