Influencia del genotipo y la densidad de inoculación sobre la diferenciación de embriones somáticos de Coffea arabica L. cv. Caturra rojo y Coffea canephora cv. Robusta

The conditions were established for the differentiation of somatic embryos from cell suspensions in the genotype Caturra rojo ( Coffea arabica ) and Robusta ( Coffea canephora ). Cell suspensions with high embryogenic potentials and stable coefficients of multiplication were used. While studying the density of inoculation, for the phase of differentiation for both varieties, differences appeared in the embryogenic capacity among them, being reached a whole of 556 500 ES.l -1 for the variety Caturra rojo and 298 670 SE.l -1 for the variety Robusta. The biggest number of embryos in torpedo state, were obtained with a density of inoculation of 0.5 gFW.l -1 for the variety Caturra rojo and 5.0 gMF.l-1 for the variety Robusta.
