El enraizamiento in vitro del manzano (Malus x Domestica Borkh.)

Abstract

La formación de raíces adventicias es muy importante como ejemplo de diferenciación, y además es muy útil para propagar plantas alogamas como los porta injertos de frutales, en los que es necesaria la multiplicacion vegetativa para conservar las características seleccionadas. En este trabajo se determino la influencia de diversos factores, se encontró una fuerte variabilidad debida al estado fisiológico de los brotes, se vio que este estado fisiológico era efímero, y que estaba influido por la duración del subcultivo anterior y las heridas basales, un efecto mediado parcialmente por síntesis de etileno, mientras que no influyen muchos otros factores. los niveles de citoquininas descienden muy poco durante el enraizamiento in vitro y la concentración típica del medio de proliferación de brotes no inhibe el posterior enraizamiento. Ninguno de los caracteres histológicos e histoquímicas estudiados se puede usar como marcador de la competencia rizogénica, excepto la actividad esterasa, que además es un buen marcador de vitrificación.

La financiación se ha debido a una beca del CONAI de la Diputación General de Aragón (BCA-16/91) y una de la CICYT (PN91-25439704); y a un proyecto del CONAI (PCA 8/89), otro de la CICYT (AGF 94-1030-C03-01), y otro de la Unión Europea (COST 87).
