Emerita V. De Guzman

NAST Academician

Expertise: Plant Physiology

An outstanding contribution of Dr. de Guzman is her series of work on the growth and development in vitro of the makapuno coconut embryo. As a result of this effort, she has revolutionized the old ratio of the makapuno-bearing nuts in the tropics which produce only 3-5 makapuno nuts in every receme bearing 14-19 nuts. Dr. de Guzman produced 100% all makapuno-bearing in the receme.
