dc.description.abstract <p>Age-age (juvenile-mature) correlations for height, diameter-at breast-height (DBH), volume, specific gravity, and fiber length were determined for a 17 year-old Alnus glutinosa (L.) Gaertn. provenance study. The correlations indicated that selection could take place at one-half the rotation age for growth traits, and one-third the rotation age for wood properties. Using early DBH to select for volume at rotation age yielded more gain per year than waiting to select directly for volume at maturity;Trait correlations were positive between growth properties. Correlations between specific gravity and fiber length were mostly positive for single trees, and negative for provenance means. Correlations between growth properties and specific gravity were slightly negative, and correlations between growth properties and fiber length were slightly positive. However, most were nonsignificant. Negative correlations between traits indicate that selecting for one trait may deleteriously affect the other;Analysis of variance showed no significant differences among provenances for either specific gravity or fiber length. There was no significant correlation between the traits and latitude of seed origin. This may have been because only a small portion of the natural range of the species was sampled. The wide variation found in both traits in individual trees indicates that genetic improvement is possible.</p>
