Resumen

Matico (Buddleja globosa Hope) is a native shrub of Chile, whose leaves are widely used inpopular medicine due to its excellent wound- and gastric ulcer healing effects. At present it is collectedfrom the wild, resulting in an over-explotation of the natural habitat and great heterogenity of thecollected material. The present investigation tried to define the most efficient big scale vegetative propagationmethodology. Matico proved to be an easy-rooting species, reaching rooting percents of about80%. Hormonal treatments with 1000 to 2000 ppm IBA (indole butyric acid) applied at the base of thecuttings promotes and accelerates the rooting process. Time of rooting does not influence the final numberof rooted cuttings, although an acceleration of the rooting process and an decrease of the survivalin springtime was observed. Studying different types of cuttings, best rooting results were obtainedwith cuttings from the apical portion of the mother-branch. A mixture of perlite and vermiculite resultedto be the most favorable rooting media. El matico (Buddleja globosa Lam.) es un arbustonativo de Chile cuyas hojas son muy usadasen medicina popular debido a su gran podercicatrizante. Actualmente es cosechado de plantassilvestres para su comercialización, conllevandoa una sobrexplotación del habitat naturaly gran heterogeneidad del material. En el presenteestudio se buscó acotar los métodos másapropiados para su propagación vegetativa agran escala. Resultó ser una especie de fácilarraigamiento, lográndose porcentajes de enraizamiento superiores al 80%. La aplicación de1000 a 2000 ppm de ácido indolbutírico en labase de la estaca favoreció y aceleró el enraizamiento.La época de enraizamiento no influyóen el número final de estacas enraizadas. Sinembargo, hubo un aceleramiento del proceso enprimavera junto a una disminución del porcentajede sobrevivencia. Respecto del tipo de estacase obtuvieron los mejores resultados conestacas provenientes del ápice de las ramasmadres y una mezcla de perlita con vermiculita(1:1) resultó ser el sustrato más favorable parael enraizamiento.
