Innovación en el procesamiento de tres grupos de semillas forestales de importancia comercia en el país

Abstract

Colombia has destined a large amount of resources for reforestation to become a productive alternative, promoting Colombian agriculture and supporting the environment. Research on forest seeds has made significant progress in identifying seed sources and a few genetic breeding programs for forest germplasm, mostly made by the private sector. However, the final quality of the forest seed is also an effect of the process of manipulation and this has remained a secondary aspect of breeding programs. Since it is useless to obtain a genetically improved seed at a higher cost, if it dies due to poor handling techniques In this work, three species of commercial importance for reforestation in Colombia were studied, from the morphology of their seeds to their benefit process. In which, it was identified phases in the current manipulation that affected its physical quality, and economic or technical aspects in the storage and the sowing. To improve this, the first prototype of the country's desalination machine was built. It was tested by a random block design with the seeds of Cedro Rosado and Walnut Cafetero. A special screen for purity enhancement in E. pellita lots was also evaluated. The results show the technical and economic advantages of applying this innovation, to the current collection systems. As well, the advantages of planting seed of superior physical quality.
