EFFECT OF INDOLE-3-ACETIC ACID ON THE VEGETATIVE PROPAGATION FOR CUTTING OF CUATOMATE (Solanum glaucescens Zucc.)

Abstract

Objective: To evaluate the effect of indole-3-acetic acid and type of rods in the vegetative propagation by cutting of the cuatomate and to describe the phenological stages, to increase production.

Design/Methodology/Approach: A completely randomized design was used by means of a 2² factorial arrangement to estimate the effect of two concentrations of indole-3-acetic acid (1000 and 10000 ppm) and type of rods (secondary and tertiary) on the number of leaves and sprout of the plant. For propagation, 30 cm rods from secondary and tertiary branches of the cuatomate were used; with cuts at the ends, transversal and diagonal; parts that generate to the dossal and root, respectively. The data were analyzed by analysis of variance with the general linear models procedure.

Results: Highly significant differences (p ? 0.01) were observed between the variables under study. Higher number of leaves and sprout (16.700 and 20.000, respectively) were observed in tertiary rods when inoculated with 1000 ppm of IAA. In the evaluation of the phenological stages, the first bud appeared at 30 days, the first leaf and flowers at 40 and 180 days after inoculation, respectively.

Limitations on study/implications: In the transversal section, commercial candelilla wax was applied to prevent possible attacks by pathogens and it was ensured that the rods are completely covered with indole-3-acetic acid.

Findings/conclusions: The use of indole-3-acetic acid in the vegetative propagation of the cuatomate would be an alternative to increase its production; promoting a sustainable activity for the Mixtec region of Puebla.
