Abstract

A Eucalyptus species and provenance trial on two sites in the Natal Midlands.

Abstract

Fourteen Eucalyptus species, each represented by 1-23 seedlots (some from selected trees, some as provenances), were planted out at 2 sites in the Natal Midlands. A table is presented showing mean diam. and vol. at age 4 yr for each seedlot at both sites. There was a significant interaction between site and species for diam., ht. and vol., and between seedlot and species for diam. and vol. The species which performed best at both sites were E. fastigata, E. saligna, E. dunnii and E. grandis. Poor performance was shown by E. laevopinea, E. nova-anglica, E. pilularis, E. pyrocarpa, E. pellita and E. urophylla. In E. saligna, best performance was shown by seedlots from Mt. Scanzi, N. Durras and Walcha (all New South Wales). Three seedlots of E. fastigata from Oakura, New Zealand, were outstanding. It is recommended that E. fastigata, E. saligna and E. dunnii be tested on a larger scale.
