Evaluación de la variabilidad genética y dasométrica de nueve procedencias de Cordia alliodora R&P (Laurel) en la estación experimental central de la amazonia (eeca), parroquia San Carlos, cantón La Joya de los Sachas, provincia de Francisco de Orellana.

Abstract

The present investigation proposed: to evaluate the genetic and dasometric variability of nine provenances of cordial alliadora R & P (laurel) in the Central Experimental Station of the Amazon (CESA), San Carlos parish, the Jewel of the Sachas canton, Francisco de Orellana Province We used a design of complete randomized blocks (DBCA) with 9 treatments and three replications, where the treatments were the nine provenances (MSL, OJSMVL,NTCBVL, 489, NTCELNTCGPL, OJS3NLQL, 490 and 590). (diameter at neck height DNH, diameter at breast height DBH, total height TH and shape factor SF. the best provenances 19 months after the trial was planted in the main characteristics were; the NTVBVL provenance in total height presented a measure of 475.27cm, the provenance 490 presented an average of 10.11 in diameter at the height of the neck and a measure of 8.14 cm in diameter at breast height. And for the factor form factor, the provenance 490 presented 0.60 (being the form factor used in this species) ), the provenances that presented the best phenotypic characteristics in: stem straightness, thickness of branches, angle of insertion of branches and the shape of the crown , were provenance: 489 (80%), NTCVBL (33%), OJS3NLQL (47%) and 490 (60%). It is concluded that the best provenances that showed good behavior and development in the environmental conditions presented in the CESA test are: NTCBVL, 490, OJS3NLQL and 489, since the evaluations at 19 months determined that these are the best provenances that presented better developments. Keywords: GENETIC EVALUATION - DOSMETIC EVALUATION - FOREST EVALUATION.
