Abstract: The Costa Rican guava (Psidium friedrichsthalianum) is a native fruit tree species of Central America cultivated in home gardens. The physical characterization of fruits and seeds of this species was done with the aim of contributing for the establishment of the implementation of techniques and commercial crops management. In this way, it was verified that the average fruit fresh weight was 42.19g, and pulp fresh weight was 39.72g, and seed fresh weight was 2.47g, with 72.8 seeds per fruit. The seeds are irregularly shaped, with average length, width and thickness of 4.29mm, 4.11mm and 2.68mm, respectively. The fruit presents favorable attributes for industrial exploitation, with high pulp yield (94%) and a round shape, somewhat flattened on the apex and base (longitudinal diameter/transversal diameter ratio = 0.83). The high seed number per fruit represents a characteristic that facilitates the propagation and seedling production of the species.
