Comparaison de la croissance d'espèces ligneuses en milieu ouvert et sous couvert forestier

Abstract

The objective of this paper is to compare growth increment between full sunlight conditions and moderately shaded conditions for seedlings of three species: sugar maple (Acersaccharum Marsh.), yellow birch (Betulaalleghaniensis Britton), and beech (Fagusgrandifolia Ehrh.). Diameter and height increments were larger in full sunlight than under cover. Yellow birch has shown better growth increments than sugar maple and beech under both conditions. This suggests that shaded conditions are not as limiting for the establishment of yellow birch than for the other two species.
