“…After the carpels have formed styles, stigmas, and ovaries, the basal portion starts to grow, at the beginning as a conical projection, and then tabular inside the young ovary locule. This meristematic cell mass forms the rudimentary nucellus of the megasporangium, that is orthotropous (atropus), but due to its initial dissimilar growth, it is twisted downward and separates its micropyle from the stigma (Hayat & Canright, 1965; Martínez Maldonado et al., 2013; Galastri & Oliveira, 2016).…”

The South American soursop, guanabana or graviola fruit, was unknown to Europeans until the voyages of Christopher Columbus. The tree is now grown commercially and in home gardens throughout the tropics. The fruit is consumed as a fresh fruit and juice, and the frozen pulp is used in the preparation of ice creams, sherbets, and juices in many world markets. The juice is sometimes mixed with other fruit juices. The pulp is also used in the preparation of drinks, wines, cakes, mousses, gelatins, and puddings or consumed green as a vegetable. This review discusses the taxonomy and morphology of the soursop, cultivar collection, and their use in selection and breeding programs as progenitors for developing new varieties.The environmental requirements, cultural practices, and plant propagation methods for soursop are reviewed. Orchard management that includes planting density, plant nutrition, pest and disease occurrence and control, harvest methods, and yields are discussed. Future prospects are considered.
