Sandalwood Identification and Analysis
- 1. Identification and oil analysis of sandalwood varieties in Vanuatu and Cape York Vanuatu Department of Forests
- 6. Methodology • Tree – Leaf length & width – Fruit diameter – Trunk diameter – Tree height – Depth of heartwood – Colour of heartwood & bark blaze – Est. bud, flower & fruit number – Heartwood core sample – Dried leaf sample – Herbarium specimen
- 7. Methodology • Environmental – GPS location – Aspect – Canopy gap fraction – Soil descriptions • Vegetation – Vegetation Type – Recruitment – Nearest Sandalwood – Species ID within 5m

- 37. Summary • Significant divergence found between populations for a range of characters • Significant tree-to-tree variation for important oil characters • Variation in heartwood %, which is independent of DBH • Heartwood and bark-blaze colour have no relationship with heartwood oil quantity or quality and cannot be used as a selection criteria • Considerable potential for short term improvement in oil quality using highest quality individuals from each population • Two highest quality populations (Santo & Malekula) are known to have a high incidence of homozygosity. • Require greater species survey to identify other ‘high quality’ populations and individuals. • Continuous variation found for all oil constituents • Very little evidence for vegetation type to have any influence on the oil characters measured • Three possible candidate species for use in the host by genotype interaction experiment Micromellum minutum, Pterocarpus indicus & Litsea imthurnei
