Micropropagation of Musa AAA cv. Poyo in the Ivory Coast

Abstract

An improved micropropagation method for the Poyo banana clone is described. Main apices of sucker buds and lateral buds are stimulated by a high concentration of benzyladenine in the absence of auxin. After transplantation, shoot proliferation is achieved with the same concentration of cytokinin. Shoot elongation and rooting are obtained simultaneously on a medium containing no phytohormone and 10 g l-1 sucrose. Rooting is improved when the bottoms of the culture tubes with the medium are set in darkness; rooting is then maximal at 97.9%.
