Tomato | Description, Cultivation, & History (2024)

tomato, (Solanum lycopersicum), flowering plant of the nightshade family (Solanaceae), cultivated extensively for its edible fruits. Labelled as a vegetable for nutritional purposes, tomatoes are a good source of vitamin C and the phytochemical lycopene. The fruits are commonly eaten raw in salads, served as a cooked vegetable, used as an ingredient of various prepared dishes, and pickled. Additionally, a large percentage of the world’s tomato crop is used for processing; products include canned tomatoes, tomato juice, ketchup, puree, paste, and “sun-dried” tomatoes or dehydrated pulp.

Physical description and cultivation

Tomato plants are generally much branched, spreading 60–180 cm (24–72 inches) and somewhat trailing when fruiting, but a few forms are compact and upright. Leaves are more or less hairy, strongly odorous, pinnately compound, and up to 45 cm (18 inches) long. The five-petaled flowers are yellow, 2 cm (0.8 inch) across, pendant, and clustered. Fruits are berries that vary in diameter from 1.5 to 7.5 cm (0.6 to 3 inches) or more. They are usually red, scarlet, or yellow, though green and purple varieties do exist, and they vary in shape from almost spherical to oval and elongate to pear-shaped. Each fruit contains at least two cells of small seeds surrounded by jellylike pulp.

The plant requires relatively warm weather and much sunlight; it is grown chiefly in hothouses in cooler climates. Tomatoes are usually staked, tied, or caged to keep the stems and fruits off the ground, and consistent watering is necessary to avoid blossom-end rot and cracking of the fruits. The plants are susceptible to a number of pests and diseases, including bacterial wilt, early blight, mosaic virus, Fusarium wilt, nematodes, and tomato hornworms. Many of these problems can be controlled with crop rotation, the use of fungicides and pesticides, and the planting of resistant varieties. The tiny currant tomato (S. pimpinellifolium) is a closely related species and has been used by breeders to hybridize several pest- and disease-resistant tomato varieties.

History

The wild species originated in the Andes Mountains of South America, probably mainly in Peru and Ecuador, and is thought to have been domesticated in pre-Columbian Mexico; its name is derived from the Náhuatl (Aztec) word tomatl. The tomato was introduced to Europe by the Spanish in the early 16th century, and the Spanish and Italians seem to have been the first Europeans to adopt it as a food. In France and northern Europe the tomato was initially grown as an ornamental plant and was regarded with suspicion as a food because botanists recognized it as a relative of the poisonous belladonna and deadly nightshade. Indeed, the roots and leaves of the tomato plant are poisonous and contain the neurotoxin solanine.

The Italians called the tomato pomodoro (“golden apple”), which has given rise to speculation that the first tomatoes known to Europeans were yellow. It has been suggested that the French called it pomme d’amour (“love apple”) because it was thought to have aphrodisiacal properties. Some scholars assert, however, that the tomato was at first taken to be a kind of eggplant, of which it is a close relative. The eggplant was called pomme des Mours (“apple of the Moors”) because it was a favourite vegetable of the Arabs, and pomodoro and pomme d’amour may be corruptions of that name.

Tomatoes were introduced to North America from Europe. Thomas Jefferson is known to have raised them at Monticello in 1781. The tomato was used for food in Louisiana as early as 1812, but not in the northeastern states until about 1835. It did not attain widespread popularity in the United States until the early 20th century. The plant is now grown commercially throughout the world.
