Propagación asexual de la especie nativa Aulonemia queko (Duda) del bosque montano de Molleturo, Provincia del Azuay

Abstract

In tropical regions there is an abundance of species diversity and natural resources, which provide a series of environmental services; they are also affected by indiscriminate logging and the increase of urban and rural infrastructure. Among them, the species Aulonemia queko, a type of bamboo, represents an important species to study due to its socio-economic impact. The objective of this research was to identify the optimal asexual propagation method for the native species Aulonemia queko (Duda). The research was of a descriptive-inferential experimental type. Through trials, a randomized complete block design (DBCA) was used, and the treatments resulted from the combination of the 5 propagation methods, and the rooting auxins "ANA and IBA" plus the tests without treatment (control), obtaining 15 treatments to which 3 replications were made, in total 45 experimental units were counted. The variables evaluated were: height, diameter, number of leaves, percentage of survival. It was found that in the ex situ propagation methods, cuttings and culms, there was no survival and in the rhizomes 0.4% of survival was obtained. Of the in situ propagation techniques, in the aerial layering, no sprouting was obtained nor was the presence of roots observed in any of the treatments. On the other hand, with respect to propagation by terrestrial layering, the treatment applied ANA stood out with 84% survival, followed by IBA with 76% and finally the control with 62.67%. This shows the positive effect of the hormones on the development of the species.
