Croissance et forme des provenances des pins tropicaux au Congo
Abstract
Growth and Form of Provenances of Tropical Pines in Congo. In order to select the necessary vegetal material for the afforestation, provenances of central America, australian and the Caribbean Sea Pinus caribaea Morelet were compared from two randomised complete block design trials. Significant differences were observed between provenances according to some quantitative characters (survival rate, height and girth growth) and form (thinness branches, pitchfork frequency, ...) 9 and 18 years after planting. It was proposed to re-introduce provenances or the best descendants from the best provenances in order to improve genetic variety. Silvicultural systems are also necessary to improve both wood quality and stand productivity.
