ll (4 to 8 cm). Their color is orange, orange-yellow, or orange-red. Their shape is spherical or oblate (flattened at the poles). The skin is thin and peels off easily. Their easiness to peel is an important advantage of mandarin oranges over other citrus fruits that all are more difficult to peel. Just like with other citrus fruits, the endocarp (inner flesh) is separated into segments, which in their turn consist of a large number of elongated cells. The fruits may be seedless or contain a small number of seeds. Mandarin orange fruits are sweet to taste. They can be eaten as whole or squeezed to make juice. They can also be dried. The fruits contain a large amount of sugar (up to 10.5%), vitamins C, B1, B2, provitamin A, free organic acids, phytoncides, lectins, and mineral salts. The vitamin C in mandarin oranges is perfectly preserved i Mandarin orange Citrus reticulata April 2013 Nordbaden.JPG Scientific classification edit Kingdom: Plantae Clade: Angiosperms Clade: Eudicots Clade: Rosids Order: Sapindales Family: Rutaceae Genus: Citrus Species: C. reticulata Binomial name Citrus reticulata Blanco, 1837 The mandarin orange (Citrus reticulata), also known as the mandarin or mandarine, is a small citrus tree with fruit resembling other oranges, usually eaten plain or in fruit salads. Specifically reddish-orange mandarin cultivars can be marketed as tangerines, but this is not a botanical classification. Mandarins are smaller and oblate, rather than spherical like the common oranges (which are a mandarin hybrid). The taste is considered less sour, as well as sweeter and stronger. A ripe mandarin is firm to slightly soft, heavy for its size, and pebbly-skinned. The peel is very thin, with very little bitter white mesocarp, so they are usually easier to peel and to split into segments. Hybrids generally have these traits to a lesser degree. The mandarin orange tree is more drought-tolerant than the fruit. The mandarin is tender and is damaged easily by cold. It can be grown in tropical and subtropical areas. According to molecular studies, the mandarin, the citron, the pomelo, and to a lesser extent the papedas and kumquat, were the ancestors of most other commercial citrus varieties, through breeding or natural hybridization; mandarins are therefore important as the only sweet fruit among the parental species. Though some mandarin cultivars remain pure, most have some degree of pomelo hybridization, while in some cases the amount of pomelo is substantial.
