| Résumé | Cassava plants were regenerated from meristems of five cultivars; Colombia No. 800, Llanera, Venezuela No. 255, Ecuador No. 133 and Mexico No. 35. Using benzyladenine (BA), gibberellic acid (GA₃) and naphthaleneacetic acid (NAA) at molar concentrations of 5·.10⁻⁷, 10⁻⁷ and 10⁻⁷, Respectively, resulted in complete plant development on Murashige-Skoog (MS) medium supplemented with vitamins as in B5. GA3 in combination with NAA resulted in root formation, while BA with NAA produced callus and storage roots. The meristems were cultured in a growth cabinet at 26°, 60% relative humidity, and exposed to a light intensity of 4000 lux from cool, white fluorescent lamps using a light and dark cycle of 18/6 h. |
