            Biriba fruits do not have a long shelf life.  Fruits start turning black and spoiling in 2-3 days after harvesting.  Therefore commercial cultivation of this fruit is possible only around big cities only.

            Biriba is usually grown from seed, but superior cultivars may be propagated by grafting.  It can be grafted onto rootstocks of Annona montana or Annona glabra, which causes dwarfing.  Seeds remain viable for up to 3 years if they are kept cool and dry.

The trees grow well on acid soils in the wet tropics, and tolerate some shade, although it grows best in full sun.  Biriba is fast growing, and begins to fruit at 3-4 years from seed.

The fruits are attractive to birds and other animals, and should be harvested when they start to turn yellow, and ripened in a protected place.   Mature fruits are soft and easily bruised.


The only named selection referred to in the literature is Regnard.  It was reported by P.J. Wester in 1917 as the best variety introduced into the Philippines. A large fruited type also exists in the western Amazon region.  This has very pronounced points and the fruits weigh up to 4 kg.


Pulp, which comprises 70% of the total fruit, is eaten fresh.  It is also made into juices and deserts.   The pulp is also fermented to make wine in Brazil.

The seeds are used to make an insecticide by grinding and macerating in water.

The wood of Biriba tree is yellow, hard, heavy, strong and is used for ribs for canoes, boat masts, boards and boxes.

Medicinal Uses:

Biriba fruit is regarded as refrigerant, analeptic and antiscorbutic. The powdered seeds are said to be a remedy for enterocolitis.
