Efecto de tres fitohormonas en plántulas de balsa (Ochroma pyramidale) bajo condiciones de vivero en el cantón Francisco de Orellana.

Abstract

The study consisted in evaluating the growth effects using three types of phytohormones in Ochoroma pyramidale seedlings to establish the best treatment as a mechanism for rapid development in pellets under nursery conditions in the Francisco de Orellana canton. In the methodology, an experimental study was carried out, for which, three treatments were established with phytohormones T1 Auxins (hormonagro 1), T2 Gibberellins (NewGibb 10%), T3 Cytokinins (Citokin) and T4 Control which consists of the crop under natural conditions and its three respective repetitions. A repeated measures design was established using the SPSS program in order to evaluate and search for an optimal method that provides the best conditions for the plants. For the statistical analysis, the Kruskal Wallis non-parametric analysis of variance was applied to verify that the data did not comply with the assumptions of normality and homoscedasticity. The following variables were analyzed: plant height, number of leaves per plants, stem diameter and root length. The results obtained showed the use of phytohormones obtained a better yield with T1 Gibberellins (NewGibb 10%), obtaining the greatest height with an average 20.4 cm, number of leaves/plants 6.2, and root length 9 cm. T3 Cytokinins (Citokin) had the largest stem diameter with an average 2.50 mm. It was concluded the best treatment was the phytohormone Gibberellin (NewGibb 10%), which presented a significant increase in height, number of leaves and root length, the plants being visibly the tallest and obtaining a better development. It is recommended to carry out studies with a commercial product containing the three phytohormones and to make comparisons with other growth stimulants in such a way the genetics this wood are exploited at maximum and these studies are useful by farmers.
