| description |
Cordia alliodora (laurel) wood attractive appearance, its physical and mechanical characteristics, its abundant natural regeneration, as well as the contribution to carbon sequestration and soil protection, have made it an ideal species for reforestation. However, there is insufficient good quality planting material to meet these needs and to respond to the average annual demand. Hence, vegetative propagation has become an essential tool in breeding and it is being widely used for the conservation of genotypes in clonal banks. To this end, a methodology for laurel tree epicormic shoot induction and rooting, using plant growth regulators was established. Cytokinin concentrations used for induction of shoots from adult trees were 0, 3000, 6000, 9000 mg L-1 of BAP alone and combined with 1000, 2000, 3000 mg L-1 of IAA a Complete Randomized Design (DCA) with seven treatments and three repetitions, considering each tree as a repetition, was applied. The concentrations of auxin for rooting of shoots were 0, 1000, and 1500 mg kg-1 of NAA and IBA. A factorial arrangement DCA 3 x 3 (NAA x hormone IBA) with five repetitions and five units per repetition was used. After 105 days, the induction of epicormic shoots and epicormic buds response was evaluated 2.67 buds 16.42 cm long with 6000 mg kg-1 of BAP + 2000 mg kg-1 of IAA were obtained. At 45 days rooting percentage was 54%, the number of roots was 1.78, 2.49 length 2.59 and force with 1500 mg kg-1 of NAA + 1500 mg kg-1 of IBA. This research demonstrated that using cytokinins and auxins is effective in laurel epicormic shoots induction and rooting. |

No obstante, la falta de material de siembra de buena calidad para suplir la demanda media anual, convierten la propagación vegetativa en una herramienta esencial para el mejoramiento genético, y la conservación de genotipos en bancos clonales. En este sentido, se propuso establecer una metodología para la inducción y enraizamiento de brotes epicórmicos de árboles de laurel utilizando reguladores de crecimiento vegetal. Las concentraciones de citoquininas empleadas para la inducción de brotes a partir de árboles adultos fueron de: 0, 3000, 6000, 9000 mg L-1 de BAP sola y combinadas con 1000, 2000, 3000 mg L-1 de AIA, y se determinaron utilizando un Diseño Completo Aleatorizado (DCA). Las concentraciones de auxinas para el enraizamiento de los brotes fueron de 0, 1000, y 1500 mg kg-1 de ANA y AIB, mediante un DCA con arreglo factorial 3 x 3 (hormona ANA x hormona AIB). Se evaluó la inducción de brotes epicórmicos y se obtuvieron 2.67 brotes de 16.42 cm de longitud, con 6000 mg kg-1 de BAP + 2000 mg kg-1 de AIA. El porcentaje de enraizamiento fue 54%, número de raíces 1.78, longitud 2.59 con 1500 mg kg-1 de ANA + 1500 mg kg-1 de AIB. El uso de citoquininas y auxinas fue efectivo para provocar la diferenciación celular tanto en la inducción y rizogénesis de brotes epicórmicos de laurel.Universidad Técnica Estatal de Quevedo2016-10-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.uteq.edu.ec/index.php/cyt/article/view/15710.18779/cyt.v9i1.157Science and Technology; Vol. 9 No. 1 (2016): January-June (2016); 37-43Ciencia y Tecnología; Vol. 9 Núm. 1 (2016): Enero-Junio (2016); 37-43Ciência e Tecnologia; v. 9 n. 1 (2016): Enero-Junio (2016); 37-431390-40431390-405110.18779/cyt.v9i1reponame:Revista Ciencia y Tecnologíainstname:Universidad Técnica Estatal de Quevedoinstacron:UTEQenghttps://revistas.uteq.edu.ec/index.php/cyt/article/view/157/171https://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccess2020-06-30T04:39:16Zoai:revistas.uteq.edu.ec:article/157Portal de revistashttps://revistas.uteq.edu.ec/index.php/cytUniversidad públicahttps://www.uteq.edu.ecEcuadorCiencia y tecnología1390-40431390-4043opendoar:2020-06-30T04:39:16falsePortal de revistashttps://revistas.uteq.edu.ec/index.php/cytUniversidad públicahttps://www.uteq.edu.ecEcuadorCiencia y tecnología1390-40431390-4043opendoar:2020-06-30T04:39:16Revista Ciencia y Tecnología - Universidad Técnica Estatal de Quevedofalse |
