Resumen

Objective: To evaluate the clonal behavior of Gmelina arborea Roxb from mother plant cuttings in southeastern Mexico.


Design/Methodology/Approach: A completely random design of three treatments with four repetitions was established; the treatments were concentrations of IBA (4000, 6000 and 3000 ppm). The following were evaluated: percentage of rooting, days until root formation, type of cutting, number of roots, length of roots and absorbent roots. Analysis of variance and Tukey’s test were performed with Statistix 9.0.


Results: In the analysis of variance (ANOVA), significant factors were observed (callus and number of roots), and also, a fluctuation was observed in the percentage of rooting from 84% to 92%. Regarding the number of roots and cm of roots, there were significant differences in the presence of number of roots of the 6000 ppm treatment. 


Conclusions: The concentration of IBA in the rooting generates good results in different concentrations, depending on the cutting implemented, the factors callus and number of roots; significant records were obtained between treatments, favoring the acceleration of presence of roots.
