Abstract
El presente trabajo de investigación se realizó en enero a abril del 2016 en La Capilla, Poroto, La Libertad. Se evaluó el efecto de dosis crecientes de promotores de crecimiento (Stimulate y Biomass) en el enraizamiento de Ananas comosus L. var. Roja Trujillana en condiciones de maceta. Se realizaron tres experimentos simultáneos en tres suelos distintos provenientes de tres caseríos del distrito de Poroto: Plazapampa, Poroto y Mochalito; en cada uno se empleó el diseño completamente al azar con cuatro tratamientos y cinco repeticiones. Los tratamientos fueron Testigo (t1), 0.75ml.l-1 Stimulate + 2.0ml.l-1 Biomass (t2), 1.25ml.l-1 Stimulate + 2.5ml.l-1 Biomass (t3) y 1.75ml.l-1 Stimulate + 3.0ml.l-1 Biomass (t4). Cada unidad experimentad estuvo conformada por una maceta conteniendo 2.5kg de suelo sembrado con un hijuelo de corona de 100-120 gramos de peso. El experimento fue evaluado 60 días después de la siembra, todos los datos fueron sometidos a un análisis de varianza y para la separación de medias se empleó la prueba de Tukey al nivel del 5%. Se realizó un análisis independiente para cada uno de los suelos empleados y uno en conjunto de los tres experimentos al presentar homogeneidad de variancias. Se encontró que en promedio de los tres tipos de suelo las dosis de 0.75ml/l Stimulate + 2.0ml/l Biomass y 1.75ml/l Stimulate + 3.0ml/l Biomass presentan mayor número de raíces (39.2 y 37.8 raíces por planta, respectivamente) que el tratamiento testigo (28.9 raíces por planta) sin diferencia estadística entre ambas dosis. Las dosis de promotores de crecimiento en estudio no afectan la longitud promedio de raíces, el peso seco radicular, el peso seco foliar, el número de hojas, la longitud de la hoja D, el ancho de la hoja D, ni el peso seco de la hoja “D”.
ABSTRACT The present research work was carried out in January to April 2016 in La Capilla, Poroto, La Libertad. The effect of increasing doses of growth promoters (Stimulate and Biomass) on the rooting of Ananas comosus L. var. Red Trujillana in pot conditions. Three simultaneous experiments were carried out on three different soils from three villages in the district of Poroto: Plazapampa, Poroto and Mochalito; in each one the design was used completely at random with four treatments and five repetitions. The treatments were Control (t1), 0.75ml.l-1 Stimulate + 2.0ml.l-1 Biomass (t2), 1.25ml.l-1 Stimulate + 2.5ml.l-1 Biomass (t3) and 1.75ml.l -1 Stimulate + 3.0ml.l-1 Biomass (t4). Each unit experienced was conformed by a pot containing 2.5kg of soil sown with a crown sucker of 100-120 grams of weight. The experiment was evaluated 60 days after sowing, all the data were subjected to an analysis of variance and for the separation of means the Tukey test was used at the 5% level. An independent analysis was carried out for each one of the soils used and one as a whole of the three experiments when presenting homogeneity of variances. It was found that on average of the three types of soil the doses of 0.75ml / l Stimulate + 2.0ml / l Biomass and 1.75ml /l Stimulate + 3.0ml / l Biomass present higher number of roots (39.2 and 37.8 roots per plant, respectively) than the control treatment (28.9 roots per plant) without statistical difference between both doses. The doses of growth promoters under study do not affect average root length, dry root weight, leaf dry weight, number of leaves, length of leaf D, width of leaf D, or dry weight of the "D" sheet.
