Clonal propagation of Roxb Tree Gmelina in cultivation in Southeast México

Abstract

Objective: To evaluate the clonal behavior of arboreal Gmelina roxb from stakes obtained from mother plants in Southeast Mexico.

Design: A three-treatment design with four completely randomized replicates was established, the treatments were 4000 ppm, 6000 ppm and 3000 ppm AIB concentrations. The variables evaluated are: percentage of rooting, days for root formation, type of stake, number of roots, cm of roots and absorbent hairs. The values measured in each variable were analyzed parametric ways using Statistix 9.0, Tukey test, ANDEVA.

Results: In the analysis of variance (ANDEVA) significant factors were observed (Callus and No. of roots), in the same way it was observed an oscillation in the percentage of rooting 84% and 92%, regarding the number of roots and cm of roots there were significant differences in the presence of number of roots of the treatment 6000 ppm. 

Conclusions: AIB concentration in rooting generates good results in different concentrations, according to the implemented stake, callus factors and number of roots were obtained significant records between treatments, favoring the acceleration of root presence.
