Dr. Emerita De Guzman is a Filipino scientist who is noted for her outstanding research on the propagation of pure makapuno trees.


Dr. De Guzman achieved her Bachelor's degree in Botany from the University of the Philippines in 1953. She then continued to study in Cornell University, where she obtained her MS and Ph.D. in Plant Physiology in 1956 and 1961 respectively.

Career and Contributions

Dr. De Guzman was lauded for her outstanding contribution on the growth and development, in vitro, of the makapuno coconut embryo, which resulted to the faster propagation of pure makapuno trees. With this, she has revolutionized the old ratio of the makapuno-bearing nuts in the tropics which produce only 3-5 makapuno nuts in every raceme bearing 14-19 nuts. Dr. de Guzman produced 100% all makapuno-bearing in the raceme. Aside from these, she is also recognized for devising tissue culture techniques for rapid propagation of abaca and banana. [1]

For her valuable achievements in the field of plant physiology, Dr. De Guzman received the following awards: [2]

  • Rizal Pro Patria Award, 1976;
  • Outstanding Scientist Award of the Philippine Association for the Advancement of Science, 1976; and the
  • Professional Award for Agriculture of the UP Alumni Association, 1977.
