Abstract


Quality of fruit from a green sapote (Calocarpum viride Pitt.) tree grafted onto mamey sapote [Pouteria sapota (Jacq.) H.E. Moore + Stearn] were evaluated for quality. This green sapote selection, which was donated to the University of Florida Tropical Research and Education Center by William F. Whitman, originated from scion wood collected in Honduras by W. Popenoe. Thirty fruit were harvested on 8 Feb. 2001 and allowed to slowly ripen at room temperature (24-29°C). Fruit had an ovoid shape with a persistent calyx, light green peel with an orange blush, and deep orange to salmon flesh color. The fruit ripened 4 to 14 days after harvest. At harvest, fruit ranged in size from 123 to 248 g and the mean fruit weight was 154.5 g. Upon ripening, the average weight was 133.2 g, an average of 14% moisture loss. Mean fruit length was 73 mm,  diameter 64 mm, peel weight 15 g with 80% edible flesh, and soluble solids 29°Brix. On average, there was 1 seed per fruit, mean seed weight was 11 g, and seed length was 73 mm and seed width 27 mm. The fruit peel was smooth upon harvest but had a shriveled appearance upon ripening. The ripe flesh was moist, very sweet, and had good flavor.
