Valoración de semillas de Vochysia guatemalensis, Vochysia ferruginea y Virola koschnyi
Vochysia guatemalensis, Vochysia ferruginea and Virola koschnyi are species from the wet tropical forest, which grow at elevations below 800 masl along the Atlantic coast of Central America. All three species are becoming increasingly important for reforestation, but there is a lack of information on the seed requirements for storage and germination. The present experiments were carried out in the laboratory of CATIE Tree Seed Bank in Turrialba, Costa Rica, with replications at Danida Forest Seed Centre, Denmark, and at the Section for Horticulture, the Agricultural University, Copenhagen, Denmark. The methodology was based on the protocol of the project on 'Handling and Storage of Recalcitrant and Intermediate Tropical Forest Seeds' coordinated by IPGRI, Rome. Results showed that the seeds of V. guatemalensis and V. ferruginea are desiccation tolerant. V. ferruginea reached 93 percent germination after drying to 6.4 percent moisture content and V. guatemalensis reached 96 percent germination after drying to 5.9 percent moisture content. V. koschnyi does not tolerate desiccation below 20 percent of moisture content.
