Biological activity of biobras and Pectimorf-6 in each of the phases of micropropagation of banana (Musa sp.)
Journal Title: Journal of Research in Biology - Year 2017, Vol 7, Issue 3
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 the in vitro propagation of crops, but mush progress has been hindering due to the sufficient knowledge and impact of different phases prevailing in the micropropagation of banana hybrid 'FHIA-18' (AAAB) is present hitherto. This work was performed in order to evaluate the biological activity of an analogue of brassinosteroids (Biobras-6) *ABr+ and a mixture of oligogalacturonide with the degree of polymerization between 9 and 16 (Pectimorf) *mOLG+. The effect of ABr and mOLG are determined as a substitute or complement of auxin (IBA or IAA) and cytokinin (6-BAP) for the establishment of in vitro multiplication and rooting of plantlets and in the acclimatization phase. Non-traditional regulators phenolization decrease the explant growth in the establishment phase of in vitro propagation; but increased the number of shoots per explants (above 3.5) and improved survival of vitro plant during the acclimatization phase
