Scientist Profile


Josephine U. Agravante

Outstanding Young Scientist (1993)

Expertise: Agriculture, Postharvest Physiology

Dr. Agravante Josephine is recognized for her significant research studies on postharvest horticulture with emphasis on two important crops, the mango and the banana. Her achievements resulted not only in the improvement of postharvest systems for these crops, but in the generation of basic physiological information which can be used in designing other appropriate handling technologies that can help expand markets and minimize losses.
