Fig. 2From: Genetic improvement of wood density and radial growth in Larix kaempferi: results from a diallel mating testAge-related trends of the phenotypic values (a), individual tree heritabilities (b), ratios of variance components (c), and genetic correlations between the investigated growth ring parameters and the ring density (d). RD the average wood density of a ring, RW ring width, LWR the proportion of latewood, LD latewood density, ED earlywood density. X-axis indicates stand age. Vertical lines in a indicate standard deviations, while the lines in (b) and (d) indicate standard errorsBack to article page
