Development of genetic marking and cutting production techniques for industrial Brazilian rosewood production - ANIB@ROSA2
Rosewood essential oil is highly sought after, whether for luxury perfumes, because of its olfactory and perfume-fixing properties, or in alternative medicine, for its many therapeutic properties: among other things, it regenerates tissues and has antifungal, antibacterial and antidepressant properties. The species was harvested in such vast volumes that natural populations were exhausted, and logging was eventually banned in 2001 in French Guiana. In 2010, at the request of Brazil, the only large-scale rosewood producer, the species was even added to CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) Appendix II, leading to increasingly strict controls.
It is this situation that has prompted several players in French Guiana to think about resuming essential oil production. This could be a major lever for economic development in French Guiana, which produces exceptionally high-quality rosewood essential oil.
The Anib@rosa project’s activities centre on three pillars:
- Developing new ways of producing rosewood from cuttings;
- Studying the capacity of rosewood trees to produce suckers after cutting back and growth figures for planted trees;
- Identifying genetic markers with the aim of selecting promising individuals for genetic improvement programmes.
- A rosewood vegetative propagation procedure will have been supplied to stakeholders in the value chain.
- The capacity of rosewood trees to produce suckers after cutting back (coppicing) will have been determined and a picture of tree biomass production following initial thinning after ten years will be available.
- A rosewood reference genome will have been annotated and a reference transcriptome will be available.
Project leaders will have new knowledge to enable essential oil production on an industrial scale, within a sustainable management context that fosters conservation of the species in its natural area.
