Evaluación de la técnica de injerto en tres genotipos de Cedrela odorata L.

Background. Grafting is an effective propagation technique for cloning trees with superior characteristics. Objective. To evaluate the effect of grafting technique and genotype on graft success of Cedrela odorata L. Methodology. C. odorata grafts were made using a randomized block design with factorial arrangement. Two grafting techniques (T-side-scion and T-budding) and three genotypes selected from a provenance test (CR-1, CR-2 and CR-3) were tested. At two months, graft success (%) was evaluated. Results. The analysis detected differences in graft success due to both factors (p ≤ 0.05). T-side-scion grafting was 28.3 % more successful than T-budding grafting and clones CR-3, CR-1 and CR-2 showed differences in graft success with 52.5, 40 and 25 %, respectively. Implications. The results suggest that C. odorata trees can be cloned by T-side-scion and T-budding grafting, but it is necessary to test other techniques that increase the percentage of graft success. Conclusions. T-side-scion grafting favors graft success in C. odorata, compared to the T-budding graft. Grafting success varies depending on the genotype of scion used.
