Avances en la domesticación de Vochysia guatemalensis
Vochysia guatemalensis Sm., J.D. is a fast-growing timber tree, found naturally in the wet lowlands from southern Mexico to Panama, usually forming pure stands. Due to its fast growth and good stem form, it is being increasingly planted, mainly in Costa Rica. During the last 10 years, CATIE has implemented a number of activities aimed at the domestication of this species. These include selection of plus trees, assessment of genetic variation through provenance/progeny tests, establishment of seed orchards, capture of selected genotypes using vegetative propagation techniques and studies on seed storage and germination. In addition, field tests have been established to evaluate the performance of both clonal and seedling material, under different silvicultural systems. In this article, the advances in the domestication process of V. guatemalensis and the main research results are highlighted, and suggestions are given for the future development of the domestication strategy.

| Résumé: | Vochysia guatemalensis Sm., J.D. is a fast-growing timber tree, found naturally in the wet lowlands from southern Mexico to Panama, usually forming pure stands. Due to its fast growth and good stem form, it is being increasingly planted, mainly in Costa Rica. During the last 10 years, CATIE has implemented a number of activities aimed at the domestication of this species. These include selection of plus trees, assessment of genetic variation through provenance/progeny tests, establishment of seed orchards, capture of selected genotypes using vegetative propagation techniques and studies on seed storage and germination.
