Abstract

Variation of stem and crowncharacteristics between selected families of hoop pine (Araucaria cunninghamii Ait. ex D. Don).

Abstract

An open-pollinated progeny trial of 10 families of A. cunninghamii in Queensland was assessed to determine the importance of differences between trees and families in growth and in selected crown and stem characteristics. Univariate and multivariate analyses identified a group of 3 families that were superior for vol. u.b. and straightness. A second group of 3 families was characterized by poor straightness, large bark vol. and deep crowns. The results of these analyses demonstrate the usefulness of appropriate multivariate analysis in the interpretation of such data.
