The anon or sugar apple is a species of the Annona genus, widely
distributed in the world and in Colombia and a fruit with great
potential in domestic and international markets. However, the
technical information related to the aspects of propagation and
production is limited. In the present study, the morphological
and anatomical changes during seed germination of the sugar
apple were determined using histological techniques and photographic records. The results show that seed germination is
a process that takes place in two stages: testa rupture and endosperm rupture-radicle protrusion. In the post-germination
stages, the induction and formation of lateral roots that were endogenously produced from the primary root from the pericycle
were seen. The endosperm underwent morphological changes
that increased its volume during imbibition and degraded in
the final stages of germination, which could be indicative of
endosperm weakening and reduction of mechanical strength
imposed by embryo growth, which was required to complete
germination in A. squamosa.
