Theobroma grandiflorum, commonly known ascupuaçu, also spelledcupuassu,cupuazú,cupu assu, orcopoazu, is atropical rainforesttree related tocacao.[2] Native and common throughout theAmazon basin, it is naturally cultivated in the jungles of northernBrazil, with the largest production inPará,Amazonas andAmapá,Colombia,Bolivia andPeru.[2] Thepulp of the cupuaçu fruit is consumed throughout Central and South America, especially in the northern states of Brazil,[3] and is used to make ice creams, snack bars,[4] and other products.[5][6]
Cupuaçu trees usually range from 5–15 m (16–49 ft) in height, though some can reach 20 m (66 ft). They have brown bark, and the leaves range from 25–35 cm (9.8–13.8 in) long and 6–10 cm (2.4–3.9 in) across, with 9 or 10 pairs of veins. As the trees mature, the leaves change from pink-tinted to green, and eventually they begin bearing fruit.[7]
Flowers of cupuaçu are structurally complex, and require pollination frombioticvectors.[8] The majority of cupuaçu trees are self-incompatible, which can result in decreased pollination levels, and consequently, a decrease in fruit yields.[8] Pollination can also be negatively affected by environmental conditions. Pollinators, which includechrysomelidweevils andstingless bees, are unable to fly between flowers in heavy rains.[8]

The white pulp of the cupuaçu has an odour described as a mix ofchocolate and pineapple and is frequently used in desserts, juices and sweets.[2] The juice tastes primarily likepear,banana,passion fruit, andmelon.[9][10] Chocolate made from cupuaçu, very similar to that made from cocoa, is calledcupulate.[11]

Cupuaçu is most commonly propagated from seed, but grafting and rooted cuttings are also used.[12]
Cupuaçu trees are often incorporated inagroforestry systems throughout the Amazon due to their high tolerance of infertile soils, which are predominant in the Amazon region.[12]
Cupuaçu is generally harvested from the ground once they have naturally fallen from the tree. It can be difficult to determine peak ripeness because there is no noticeable external color change in the fruit. However studies have shown that in Western Colombian Amazon conditions, fruits generally reach full maturity within 117 days after fruit set.[13] Brazilians either eat it raw or use it in making sweets.[14]
Commercial food products include pulp and powder.[15]
Witches' broom (Moniliophthora perniciosa) is the most prominent disease that affects cupuaçu trees.[16] It affects the entire tree and can result in significant loss of yields and even tree death if left untreated. Regular pruning is recommended to reduce the severity of this disease in cupuaçu plantings.[16]
