Geographic-Variation in Seedling Morphology of Acacia auriculiformis A-Cunn ex-Benth

Abstract

Seedlings from 30 provenances from Papua New Guinea, Queensland and the Northern Territory, Australia, (and two from Thailand) were raised under common glasshouse conditions. Seventeen attributes were measured for each seedling and the resultant data subjected to univariate and multivariate analyses. Provenance differences were evident; variation amongst families within provenances was generally small. The Papua New Guinea, Queensland and Northern Territory material clustered into three distinct groups. There was a suggestion that the Queensland and Northern Territory populations were more closely related to each other than to those from Papua New Guinea. The Thai populations possibly came originally as seed from Queensland.
