Caracterización de variables dasométricas, fenotípicas foliares de quince procedencias de Cedrelingacatenaeformis D.Ducke (Chuncho), en el cantón La Joya de los Sachas, provincia de Orellana.

Abstract

The present investigation aims at characterizing dasometric, phenotypic and foliar variables coming from 15 provenances of Cedrelinga catenaeformis D. Ducke (chuncho), in the canton of Joya de los Sachas, province of Orellana. A randomized complete block design (RCBD) was used for the fifteen provenances (Bolívar García, Rosmel Benalcázar, Juana Chela, José Tapuy, Ángel Torres, Andrés Jaramillo, Olga Ramírez, Fredy Moreno, La belleza, Oswaldo Puraquilla) and three repetitions during the first sixth months of plantation. Dasometric variables (diameter at the height of neck, total height TH), leaf area, quality of soil and weather conditions were evaluated getting that the provenance Bolívar García overtakes in DAC with an average of 1.72 cm, this value overtook the ones gotten in the investigations carried out in Colombia, Perú y Brasil. Regarding to the height of provenance Olga Ramírez, we got the most outstanding average of 57.24 cm. This value is around the half of the value gotten in the investigation carried out in Perú and the other countries. The leaf area was not taken into account in the selection of the best precedence because it does not have meaningful differences in the growing among provenances. As regard to edaphoclimatic conditions, it is concluded that they are good for the development of this specie. We cannot consider that the provenances mentioned above are the best in diameter and height because evaluation time was short and the forestry species need at least a three-year period.

KEY WORDS: TEST – DASOMETRIC EVALUATION – LEAF AREA – EDAPHOCLIMATIC CONDITIONS.
