Sisal with the botanical name Agave sisalana, is a species of Agave native to southern Mexico but widely cultivated and naturalized in many other countries. It yields a stiff fibre used in making various products. The term sisal may refer either to the plant's common name or the fibre, depending on the context. It is sometimes referred to as "sisal hemp", because for centuries hemp was a major source for fibre, and other fibre sources were named after it.
The sisal fibre is traditionally used for rope and twine, and has many other uses, including paper, cloth, wall coverings, carpets, and dartboards.
The native origin of Agave sisalana is uncertain. Traditionally it was deemed to be a native of the Yucatán Peninsula, but there are no records of botanical collections from there. They were originally shipped from the Spanish colonial port of Sisal in Yucatán (thus the name). The Yucatán plantations now cultivate Henequen (Agave fourcroydes).
H.S. Gentry hypothesized a Chiapas origin, on the strength of traditional local usage. Evidence of an indigenous cottage industry there suggests it as the original habitat location, possibly as a cross of Agave angustifolia and Agave kewensis. The species is now naturalized in other parts of Mexico, as well as in Spain, Libya, Morocco, the Canary Islands, Cape Verde, many parts of Africa, Madagascar, Réunion, Seychelles, China, the Ryukyu Islands, India, Pakistan, Nepal, Burma, Cambodia, Thailand, the Solomon Islands, Queensland, Polynesia, Micronesia, Fiji, Hawaii, Florida, Central America, Ecuador, and the West Indies.
Sisal plants, Agave sisalana, consist of a rosette of sword-shaped leaves about 1.5–2 metres (4.9–6.6 ft) tall. Young leaves may have a few minute teeth along their margins, but lose them as they mature.
The sisal plant has a 7–10 year life-span and typically produces 200–250 commercially usable leaves. Each leaf contains an average of around 1000 fibres. The fibres account for only about 4% of the plant by weight. Sisal is considered a plant of the tropics and subtropics, since production benefits from temperatures above 25 degrees Celsius and sunshine
Sisal was used by the Aztecs and the Mayans to make crude fabrics and paper.
In the 19th century, sisal cultivation spread to Florida, the Caribbean islands, and Brazil (Paraiba and Bahia), as well as to countries in Africa, notably Tanzania and Kenya, and Asia.
The first commercial plantings in Brazil were made in the late 1930s and the first sisal fibre exports from there were made in 1948. It was not until the 1960s that Brazilian production accelerated and the first of many spinning mills was established. Today Brazil is the major world producer of sisal. There are both positive and negative environmental impacts from sisal growing.
Propagation of sisal is generally by using bulbils produced from buds in the flower stalk or by suckers growing around the base of the plant, which are grown in nursery fields until large enough to be transplanted to their final position. These methods offer no potential for genetic improvement. In vitro multiplication of selected genetic material using meristematic tissue culture (MST) offers considerable potential for the development of improved genetic material.
