It is widely used in industries, thereby sustaining the Philippine economy. Vegetative propagation using somatic embryogenesis over conventional seed propagation is essential as this results to better quality and uniform plantlets with higher yield. In this study, culture vessel (glass jar with polypropylene sheet and rubber band and screw-capped test tubes), sugar sources (sucrose, white, and brown table sugar), and coconut varieties (Laguna Tall and Catigan Dwarf) were evaluated for their influence on calloid growth. Results revealed that callus growth was observed after the first four weeks of culture. Highest quality of callus was produced with the following factors: coconut plumule from Laguna Tall with brown sugar as its sugar source and screw-capped test tubes as culture vessel. Partially differentiated callus, calloid, was observed after sixty days of culture with good quality. In terms of costs, use of screw-capped test tubes and Catigan Dwarf coconut were more expensive than glass jar and Laguna Tall coconut, suggesting possible cheaper and sustainable materials for coconut micropropagation.
