The survival, growth and wood basic densities of 14 year old<i>Eucalyptus camaldulensis</i>at Michafutene, Mozambique

SYNOPSISVariation in performance of several Eucalyptus species/provenanceslland races, Casuarina equisetifolia, Leucaena leucocephala and Senna siamea was evaluated in two 14 -year old trials planted at Michafutene, Mozambique. At the age of 6, 10, and 14 years, data were collected of survival, breast height diameter, height and stem form. Wood basic density was only measured at the final assessment occasion. Significant differences between species, provenances and land races were found in survival, growth and stem form. Wood basic density was not significantly different between species, provenances and land races. Overall, growth of Eucalyptus species/provenances from the natural range (Queensland, Australia) was found to be superior to that of sources (land races) form Brazil, Zimbabwe and Mozambique. The performanance of C. equisetifolia, L. leucocephala and S. siamea land races was also poor. The following outstanding species and provenances are recommended for planting at Michafutene and similar sites: E. tereticornis (ex. S. Helenvale), E.brassiana (ex. SE Coen), E. cloeziana (ex. Stannary Hills) and E. camaldulensis (ex. Petford). For E. cloeziana, testing of additional provenances is recommended since only one provenance was tested in these trials.

Eucalyptus globulus trees, 15 years old, were sampled at different heights from commercial pulpwood plantations in two sites in Portugal. Bark thickness was higher in the site with better growth and always decreased from the tree base to the top. Bark content was site independent and on average 11% of stem dry weight, higher at the base and top, and lower at 35% height level.Tree mean wood basic density averaged 600 kg /m3 and 568 kg /m3 for best and worst site, respectively, and was not correlated with tree growth. Wood density increased from base to top of the tree. Between-tree variation was low with coefficients of variation of site mean below 10%. Bark density (374 kg /m3 and 454 kg /m3 for best and worst site, respectively) did not show significant within tree variation. Average tree wood density could not be predicted with reasonable accuracy using a breast height sampling and better results were obtained using a sampling as a percentage of total height (e.g. 15%).
