Mineral nutrition is related to the growth and reproduction physiology of Annonaceae. Each species of Annona genus has a genetic load that presents specific nutritional requirements for their metabolic functions. The absorption march of nutrients is fundamental for determining the appropriate development stage and doses of applying fertilizers and getting the maximum productive yield. There are few scientific studies about nutrition and fertilization in this family, in spite of requiring large amount of nutrients. This study has the purpose of presenting major mineral requirements in Annona genus, with emphasis on custard apple (A. squamosa) and soursop (A. muricata), related to vegetative and reproductive growth and fruit quality (sugar content, acidity, firmness and crack fruit, etc.). The mineral absorption march in soursop during growth of seedlings is in decreasing order: K>N>Ca>Mg>P and Fe>Zn>Mn>Cu. Significant amount of N, K, Ca, Mg and P are extracted by Annonaceae as compared to other fruits. The export of nutrients by sugar apple is superior to those exported by oranges, pineapple, avocado and many other fruits. In respect of the micronutrient is known that B and Zn are very important in tropical soil with pH below 6.5. Nevertheless, in soil with pH superior to 7.0 Fe and other micronutrients may be restrictive to Annona growth and reproduction. The increasing importance of fresh and processing markets requires scientific investigations in absorption march and nutrition for the various species of Annonaceae.

Several species of Annonaceae family produce edible fruit. They are cultivated in commercial orchards or collected in an extractivism way in different parts of the world. The Annona genus has many species, but only a few of them are edible. Among them only a few ones are commercially cultivated, the most important economically are: (soursop) Annona muricata, (custard apple) Annona squamosa and Annona cherimola (cherimoya) especially; atemoya (hybrid between A. squamosa x A. cherimola) also presents in increasing importance. They are important economically for many countries in Africa, Asia and America (Central, North and South). The main producing countries are: cherimoya production in Australia, Chile, Spain, the United States, New Zealand and Israel in soursop; Mexico, Brazil, Venezuela and Costa Rica in custard apple: India, Brazil, Thailand, Philippines and Cuba. Fruit yield of Annonaceae in several producing countries is relatively low, due to the inappropriate use of management techniques (irrigation, fertilization, pruning, pollination, insect and disease control, etc.). In Brazil, the most important commercial crops with Annonaceae are: custard apple, soursop and atemoya. The objective of this study is to present the current status and perspectives for the Annonaceae in Brazil and worldwide. The cultivation is characterized mainly by small farmers, especially using the family labor. In general it can be considered that this group of fruits presents increasing important socio-economic values within the producing countries, but considering international market it recently presents more and more importance, because of their status as exotic fruit showing excellent qualities, including the functional value, such as vitamins, antioxidants and other functional properties. The increase in consumption of Annonaceae may be intensified if the producing countries implement an aggressive marketing program demonstrating its nutritional and functional qualities for consumers' health.
