Breadfruit is the term used to describe two unrelated broad categories of edible plant. Treculia africana or african breadfruit and Artocarpus Altilis from the Pacific. Treculia africana is grown for its edible seed. Artocarpus Altilis is grown for its fleshy inside and is grown widely in the Pacific and the Caribbean.
African breadfruit (Treculia africana)--English (wild jackfruit, African breadfruit, African boxwood); French (abre á pain d' Afrique); Luganda (muzinda); Swahili (mwaya); Wolof (brebretim)-- tends to be larger than the Pacific breadfruit. Inside, the bulbous fruit, are lots of edible seeds. It can be found in tropical Africa especially West Africa and is very common in countries like Nigeria. The African breadfruit is valued for its seeds. The Pacific variety , also found in the Caribbean, is valued for its fleshy part. The Pacific variety does not have seed.
Treculia africana is grown from seed , budding, cuttings, and shield grafting. It loves semi shady areas like the rain forest environment. Plants that are budded grows fastest about 2-4 years. Plants that are grown from seed takes the longest to mature and bear fruit. The African breadfruit does not require a lot of sun. It can grow in tropical and subtropical conditions.
Pacific Breadfruit (Artocarpus Altilis) is the most common breadfruit. When people say breadfruit, they are usually refering to Pacific Breadfruit. It was domesticated in the the Malay archipelago and brought to the Caribbean as an inexpensive source of food for slaves. It produces no seeds. The plant is grown from root shoots or root cuttings. It loves wet and well drained soil. Fertilizer of composted bark, peat moss, or coconut husk is ideal. The plant should be regularly watered at the base near the roots. Soil should be kept at a pH 6.1–7.4.
As far as Climate Change, the Pacific breadfruit is not labor intensive. It retains top soil and nutrients, a good crop for increasing food security and preveinting soil errosion. In regions, like the Caribbean and parts of Africa, Brazil, this is a great cover plant.
