Research Note: ERDB Research, Development and Extension Strategies for the Production of High Quality Planting Materials

Author(s): Rafael Cadiz, Marilyn Landicho and Mylene Aparente


The Ecosystems Research and Development Bureau of the Philippine Department of Environment and Natural Resources (DENR), is presently conducting research, development and extension strategies for the production of high quality planting materials. The activities include the verification and assessment of existing seed stands and identification of new seed stands, as seed sources of indigenous and exotic species nationwide. Propagation protocols are being developed for some demand-driven indigenous species, and provenance cum progeny trials are being conducted for narra (Pterocarpus indicus), yemane (Gmelina arborea) and molave (Vitex parviflora). Extension activities include the establishment of a database of the information gathered by the project, capacity building, and production of brochures, leaflets and videos. It is considered that all possible mechanisms should be employed to transfer the research results effectively.

Keywords: propagation protocols, seed stands, provenance and progeny testing, data base establishment, GIS-based map
