ABSTRACT Byrsonima crassifolia L. Kunth is a plant native to the Americas that grows in tropical and subtropical areas. Fresh B. fruits are good source of ascorbic acid carotenoids contain volatile compounds such as butyric caproic acids. Although commonly exploited from wild natural ecosystems, it exhibits potential become crop plant. When optimal agronomic management systems support propagation by seed, with more homogeneous characteristics can be produced compared those obtained or...
