Evaluación de la inducción de embriogénesis somática a partir de primordios foliares de curuba (Passiflora tripartita (Juss.) var. mollisima (Kunth) L.H Bailey).

Abstract

The “Curuba” (Passiflora tripartite var. mollisima) is an exotic fruit of great economic importance to both locally and internationally. This is due to its particular taste and high vitamin content. Sexual propagation presents several drawbacks at a productive level, because there is not a uniform germination, viability of seeds percentages tend to be low in this genre, originating plants with high genetic variability expressed in differences of growth, vigor, performance and quality of the fruit, expressed in economic losses for the producers, for which reason vegetative propagation that arises as an alternative to the production of this fruit tree, since this ensures uniformity and viability in the product. This research focused precisely on a technique of vegetative propagation which has so far not had been applied in this species, known as somatic embryogenesis, in order to secure a solution to the problem proposed. The effect of the orientation of the explants was determined, as well as the concentrations of growth regulators used. The presence of embryonic tissue by means of histological processing was confirmed.
