Genetic Control Of Dry Matter Distribution In Twenty Half-sib Families Of Virginia Pine

Half-sib progeny derived from 20 Pinus virginiana parent trees were sampled, at age eight, to determine presence of significant among family differences in the distribution of dry matter. Families differed in branch weight but not in stem wood, stem bark, leaf, or total wood weight. Proportionate distributions of dry weights for stem, wood branch and stem bark were significantly different among the 20 families. Differences in proportionate distributions were independent of tree size. Heritability (h2) estimates were high for the stem weight and wood weight proportion of dry weight but only moderate for height, diameter and branch weight. Additional keywords: Biomass, Pinus virginiana, dry matter distribution.
