Propagación sexual y asexual de la cascarilla (Cinchona officinalis L.), con fines de potencial reproductivo en el vivero Catiglata del Consejo provincial de Tungurahua

Abstract

The research proposes to evaluate the sexual and asexual propagation of the Cascarilla (Cinchona officinalis L), for purposes of productive potential in the Catiglata nursery of Consejo Provincial de Tungurahua. It is located in Izamba parish, its development involved a single type of substrate and the use of biological fertilizer (Mycorrhiza liquid and powder) in Cascarilla seeds (Cinchona officinalis L) .Two types of rooting hormones (Hormonagro 1 and Phytoroot) in the stakes of Cascarilla (Cinchona officinalis L); A nonparametric statistical design of Kruskal Wallis was used, and the application of the statistical part was at the end of the trial period at 90 days. As a satisfactory result, as well as in a higher percentage, of germination, T1 and T2 were obtained, with 61.67%. The average beginning of germination was at 25 days, stabilized and declined at 70 days. As for the stakes of Cascarilla (Cinchona officinalis L), it did not respond to the asexual vegetative propagation with the applied treatments, because it is a specie with very woody characteristics and lack of knowledge at their age; which prevent the proliferation of roots and the advance of new shoots. Since the seeds of Cascarilla (Cinchona officinalis L), are small and spread immediately after opening the fruits. It is recommended to perform a rapid collection and sowing to avoid losing their germinate capacity and to carry out future tests of asexual propagation in Cascarilla (Cinchona officinalis L), taking into account other factors such as: plant age, phonological state of the tree, harvest season, lunar phases.
