Effect of indole-butyric acid on the propagation of tacaco (Sechium tacaco) by air layering

Abstract

Objectives:  evaluate the effect of different doses of IBA on the vegetative propagation of tacaco (Sechium tacaco) using air layering.  Methodology: The trial was carried out in Fraijanes, Alajuela, in August-September 2017. Three doses of AIB (200, 600 and 1,800ppm) and a control with distilled water were evaluated. 10 air layers were performed for each treatment. The percentage of live layers, and the production of callus and roots in each layer, were evaluated.  Results: The percentage of live layers ranged between 80 and 90% for all treatments. The percentage of callus production varied between 44 and 75%. There was no root production in any treatment.  Conclusions: The use of IBA for the vegetative reproduction of tacaco through air layering was not effective using the methodology tested in this work.
