Abstract
Esta investigación se realizó partiendo de la preocupación por la sostenibilidad y la productividad de las industrias básicas, como tema que ha llevado a cuestionarse si la generación de bienes provenientes de la agricultura merece ser comercializada, o si estos deben pasar por procesos de penalización debido a los problemas ambientales a los que se les asocia. En este sentido, se ha producido cultivos de manera constante, abusando del uso de gran cantidad de insumos sintéticos; lo que ha dejado una huella contaminante reflejada en una bio acumulación de sustancias nocivas. En función de esto, se identificó como problema central: ¿Qué dosis de quitosano y a que tiempo de inmersión resulta ser más eficiente en el enraizamiento de patrones de rosas Natal brier?, se determinó como objetivo principal la validación del efecto del quitosano como bioestimulante en el desarrollo del sistema radicular de estos patrones, en el cantón San Pedro de Huaca, provincia del Carchi; donde se plantearon las siguientes variables dependientes: Días a la brotación de la yema, Largo de la yema 60 días después de la siembra, Masa Foliar 60 días después de la siembra, Masa Radicular 60 días después de la siembra. Obteniendo como resultado respecto del tiempo de brotación de las yemas foliares, que el empleo de quitosano a diferentes dosis y tiempos de inmersión del material vegetal, no muestra un efecto bioestimulante en los procesos fisiológico de emisión foliar, así como también el tamaño de la yema foliar y la masa foliar y radicular en materia seca; razón por la cual no se encontró una relación bioestimulante del quitosano en una mejora de la producción de patrones de rosa.
This research was carried out based on the concern for the sustainability and productivity of basic industries, as an issue that has led to the questioning of whether the generation of goods from agriculture deserves to be marketed, or if they should go through penalization processes due to associated environmental problems. In this sense, crops have been produced constantly, abusing the use of a large amount of synthetic inputs; which has left a polluting footprint reflected in a bio-accumulation of harmful substances. Based on this, the central problem was identified: What dose of chitosan and at what immersion time turns out to be more efficient in the rooting of Natal brier roses? the validation of the effect of chitosan as a biostimulant in development will continue as the main objective. of the root system of these rootstocks, in the San Pedro de Huaca canton, Carchi province; where it was proposed as dependent variable: Days to bud sprouting, Bud length 60 days after sowing, Foliar Mass 60 days after sowing, Root Mass 60 days after sowing. Obtaining as a result regarding the sprouting time of the leaf buds, that the use of chitosan at different doses and times of immersion of the plant material, does not show a biostimulant effect on the physiological processes of leaf emission, as well as the size of the bud. leaf and leaf and root mass in dry matter; reason for which a biostimulant relationship of chitosan in an improvement of the production of rose patterns was not found.
