Sugar cane is a tall perennial grass in the genus Saccharum that is cultivated mainly for the sucrose-rich juice in its stalks, which is processed into sugar. It is an important tropical and subtropical crop used for sugar production and, in some regions, for ethanol and other by-products.

Description

Sugar cane is a tall, jointed grass with fibrous stalks that store sucrose in the stem internodes. The plant typically grows about 2–7 metres tall and is primarily grown in warm tropical and subtropical regions.

Origin and domestication

The plant is native to New Guinea and spread widely through tropical Asia and beyond through domestication and trade. Sources differ on the precise original domesticated region, but they agree that it originated in tropical Asia or the New Guinea region.

Cultivation and uses

Sugar cane is grown in tropical and subtropical climates around the world. Its main use is sugar production, but it is also used for ethanol, rum, paper, fibreboard, fuel, and animal feed.

Economic importance

Sugar cane is one of the world’s most important commodity crops. It accounts for a large share of global sugar production and remains a major agricultural crop in many tropical countries.

Key facts

  • Sugar cane is a tall perennial grass in the genus Saccharum, grown for its sucrose-rich stalks.
  • It is primarily cultivated in tropical and subtropical regions for sugar production.
  • Cultivated sugar cane is commonly identified with Saccharum officinarum, though modern crops often include hybrids.
  • The plant is also used for ethanol, rum, paper, fibreboard, fuel, and animal feed.
  • Sugar cane is one of the world’s most important commodity crops, especially in tropical countries.

Canadian context

Sugar cane is not widely grown in Canada because it requires a warm tropical or subtropical climate, but Canadian readers encounter it as the main source of global sugar and in products such as sugar, molasses, rum, and ethanol.

Frequently asked questions

What is sugar cane?
