摘要：This article describes a method to increase the germination rate of Bursera graveolens, a socially, commercially, and ecologically valuable tree species in southwest Ecuador and northwest Peru. The species suffers from (regional) unsustainable harvesting for its aromatic resin. Increased propagation success could lead to increased use of the tree in reforestation, restoration, and social forestry projects and on industrial plantations. Ecological observations of B. graveolens were made while the primary author managed the reforestation program and tree nursery in the Cerro Blanco Protected Forest in Guayaquil, Ecuador (2˚11’ S. and 79˚53’ W.), from 1995 to 2006.
