Grapefruit is one of the important citrus fruits (see citrus fruits). The tree tends to be more vigorous than orange, especially when young, with larger and thicker leaves. Fruit is near round to oblate, 3 to 4.5 inches in diameter with a rather thick rind. Varieties may be seeded or seedless, and flesh may be white or pink. Fruit sets in small clusters on vigorous trees.
Production in U.S.: About 1,500,000 tons.
Use: Fresh, canned juice and segments, marmalade.
Part of fruit consumed: Interior segments or juice. Rind from processing plants is dried for livestock feed.
