Agregar Etiqueta | Sumario: | Paulownia is a plant species with large foliage, originally from China that for more than 20 years has been studied and subjected to experiments in Australian and American laboratories, in order to accelerate its growth. The Paulownia tree has become a new timber alternative that reduces harvesting time due to its warmth, rapid growth and high production expectations, considerable biomass production and CO2 fixation capacity. The research work was carried out in the Laguacoto II sector, Guaranda canton, Bolivar province. The micropropagation of paulownia (Paulownia tomentosa) explants was evaluated by applying three types of cytokinins in four doses. The objectives of this research were i) To determine which of the three hormones has a better development. ii) To analyze the effect of the doses on the sprouting of the explant. iii) To establish the benefit-cost of the treatments under study. The methodology applied was a completely randomized experimental design with three replications and twelve treatments. Paulownia explants were propagated by applying three types of cytokinins in four doses in the Laguacoto II biotechnology laboratory. An analysis of variance, Tukey's test at 5% was carried out to compare the averages between treatments and factors under study. According to the results, the treatment with the highest number of shoots per explant was T11: Kinetin 5 mg/l with 6 shoots, as well as T12: Kinetin 7 mg/l with 6 shoots. The best cost benefit in the twelve micropropagation treatments was given by T11 with a profit of $1.96 per unit invested, followed by T12 with a profit of $1.95 per unit invested. |
