Evaluación de tres sustratos en la propagación asexual de kiri Paulownia tomentosa en el sector El Progreso, provincia Cotopaxi.

Abstract

This research aimed to carry out a combination of three types of substrates to know which one provides the best benefits in its growth and adaptability to Paulownia tomentosa. The essay included processes that consisted of the preparation of the site, in which silvicultural tasks were carried out such as cleaning the land and construction of the essay. The Complete Random Design (CRD) was obtained through the Analysis of Variance. Data from the individuals studied at 20, 40 and 60 days after being planted were taken. These data were height, diameter at neck height (DNH), number of leaves and length of the root at 60 days, using instruments such as a tape measure and a vernier caliper to take the DNH data on their corresponding days. 60 days after the last data from the plants was taken, better results were obtained both in height and in number of leaves and root length for (T1). It was also observed that the DNH had no relevance between treatments. For the capture of the species, it was observed that at 60 days a greater number of species was obtained. No significant differences were found for the treatments in the statistical analysis. It was concluded that plants react better to substrates that do not have much moisture retention. It was recommended to work with this species in the summer season for the El Progreso sector and to carry out the work in a greenhouse to control the temperature and humidity conditions.
