Análisis de tres sustratos y tres dosis de fitohormonas para la reproducción asexual de (Pópulus alba) en la fundación Inti, cantón Riobamba, provincia de Chimborazo.

Abstract

This study focused on the analysis of three substrates and three doses of phytohormones for the asexual reproduction of (Pópulus alba) in Inti foundation, Riobamba canton, province of Chimborazo, the research was carried out with the purpose of analyzing the effects of the substrates: (black soil, compost, rice husk); where it was used in combination with the three doses (0cc, 15cc and 25cc) of the phytohormone (RootMost), with an experimental design of Randomized Complete Blocks (DBCA) with bi-factorial structure, with nine treatments and three replications, in a period of thirty to forty-five days. The trial included a temporary nursery preparation phase, substrate preparation, and selection of the mother plant for the extraction of cuttings. The most effective treatment for the propagation of (Pópulus alba) was T1 (0cc, 100% black soil), which remains in the best range showing a better performance in all evaluations during the research, where significant differences can be evidenced with notoriety in the percentage of budding and number of shoots being the most propagated during the entire research process, the data collected from production costs was obtained a low unit cost of 0.20 cents. This show that the production with this type of research is profitable, it is recommended that in future researches they do not take into account few days of research, and work with other types of organic materials.
