Jackfruit - 10 to 15 lbs. The jackfruit should not to be confused with the Durian fruit. The jackfruit is native to India, Bangladesh, and Nepal. The jackfruit is commercially grown and sold in South, Southeast Asia and northern Australia. It is also grown in parts of Hawaii, Brazil, Suriname, Madagascar, and in islands of the West Indies such as Jamaica and Trinidad.
The jackfruit is the national fruit of Bangladesh and Indonesia. All jackfruit plants are frost sensitive. The jackfruit bears fruit three years after planting.
The jackfruit has played a significant role in the Indian agriculture (and culture) from time immemorial. Archeological findings in India have revealed that jackfruit was cultivated in India 3000 to 6000 years ago. Findings also indicate that Indian Emperor Ashoka the Great (274–237 BC) encouraged arbori-horticulture of various fruits including jackfruit. Varahamihira, the Indian astronomer, mathematician, and astrologer wrote a chapter on the treatment of trees in his Brhat Samhita. His treatise includes a specific reference on grafting to be performed on trees such as jackfruit.
Recently, the jackfruit has been considered as an invasive species in Brazil, specially in the Tijuca Forest National Park in Rio de Janeiro. The Tijuca forest being mostly an artificial secondary forest, whose planting began during the mid-XIXth. Century, jackfruit trees have historically made part of its flora since the park's founding. Recently, however, it was considered that the species had begun to expanded excessively due to the fact that its fruits, once they had naturally fallen to the ground and opened, where eagerly eaten by small mammals such as the common marmoset and the coati. As both animals also prey opportunistically on bird's eggs and nestlings, the supply of jackfruit as a ready source of food has allowed them to expand their populations at the expense of avian life. Also, as the seeds themselves are also dispersed by the same animals, this allows the jackfruit to compete for espace with native tree-species; therefore the fact that, between 2002 and 2007, 55,662 jackfruit saplings have been destroyed in the Tijuca Forest area alone in a deliberate culling effort by the park's management; at the same time, 1,921 young trees were felled and 881 mature ones were killed through girdling.
