Efecto de tres enraizadores y tres sustratos en la propagación vegetativa de yagual (Polylepis incana) en el cantón Tulcán, provincia del Carchi.

Abstract

The aim of this study was to evaluate the effect of three rooting agents and three substrates on the vegetative propagation of Yagual (Polylepis incana), determining if the rooting agents and their combination with a substrate have an effect on the percentage of budburst and vegetative development, data was collected at 20, 40 and 60 days, evaluating the following variables: percentage of rooting, plant height, number of leaflets, root length and root weight. ANOVA was used for the analysis of variance, with separation of means according to Tukey at 5% using InfoStat software. In the percentage of rooting, significant differences were found in the rooting factor, with 18.33% in Rootex rooter, 13.33% without rooter and 5.83% in organic rooter (bee honey), in plant development, there were no significant differences in plant height and number of leaflets, while in root development, the Friedman test identified S1E1 (black soil 50% + humus 25% + sand 25% + rootex) as the best treatment, with 3.21 cm in root length and 3.21 cm in root weight, while S1E2 (black soil 50% + humus 25% + sand 25% + rootex) was identified as the best treatment, 21 cm in root length and 5.16 g in weight. It is concluded that the chemical rootex rooting agent helps to stimulate both the take root and the development of the plant in combination with the S1 substrate (black soil 50% + humus 25% + sand 25%), it is suggested to carry out studies in similar conditions to the species’ habitat or higher than 3000 meters above sea level to verify if the height provides better results.
