ABSTRACT: The use of biotechnology in the propagation of plantain and banana (Musa sp.) of great importance to induce, tolerant to plant genotypes for diseases and high yield potentials. However, auxins and cytokinins should be used, which are expensive and can sometimes cause changes in the regenerants obtained. Both traditional growth regulators (auxins and cytokinins) and non-traditional growth regulators (brassinosteroid analogues and mixtures oligogalacturonide) are used in Institution: the in vitro propagation of crops, but mush progress has been hindering due to the 1. Doctor en Ciencias Agrícolas. Investigador Auxiliar. sufficient knowledge and impact of different phases prevailing in the Departamento de Fisiología y micropropagation of banana hybrid 'FHIA-18' (AAAB) is present hitherto. This work Bioquímica Vegetal. Instituto was performed in order to evaluate the biological activity of an analogue of Nacional de Ciencias Agrícolas. Carretera a Tapaste Km 3 ½ San brassinosteroids (Biobras-6) *ABr+ and a mixture of oligogalacturonide with the degree José de las Lajas, Mayabeque. of polymerization between 9 and 16 (Pectimorf) *mOLG+. The effect of ABr and mOLG Cuba. C. P. 32 700. are determined as a substitute or complement of auxin (IBA or IAA) and cytokinin (62.Doctora en Ciencias Agrícolas.

Non-traditional regulators phenolization decrease the explant Departamento de Genética y growth in the establishment phase of in vitro propagation; but increased the number Mejoramiento de las Plantas. of shoots per explants (above 3.5) and improved survival of vitro plant during the Instituto Nacional de Ciencias Agrícolas.
