Clementine

A clementine (Citrus × clementina) is a tangor, a citrus fruit hybrid between a willowleaf mandarin orange (C. × deliciosa) and a sweet orange (C. × sinensis),<ref name="Hybrid">Template:Cite journal</ref><ref name="genealogy">Template:Cite journal</ref><ref>Template:Cite journal</ref> named in honor of Clément Rodier, a French missionary who first discovered and propagated the cultivar in Algeria.<ref name="Edible">Template:Cite book</ref> The exterior is a deep orange colour with a smooth, glossy appearance. Clementines can be separated into 7 to 14 segments. Similar to tangerines, they tend to be easy to peel. They are typically juicy and sweet, with less acid than oranges.<ref name="Edible" /> Their oils, like other citrus fruits, contain mostly limonene as well as myrcene, linalool, α-pinene and many complex aromatics.<ref name="Ziegler">Template:Cite book</ref>

They are sometimes sold under the name Easy-peelers.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

The clementine is a spontaneous citrus hybrid that arose in the late 19th century in Misserghin, Algeria, in the garden of the orphanage of the French Missionary Brother Clément Rodier, for whom it would be formally named in 1902.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref><ref>Template:Cite book</ref> Some sources have attributed an earlier origin for the hybrid, pointing to similar fruit native to the provinces of Guangxi and Guangdong in present-day China,<ref name="Saunt">Template:Cite book Template:Page needed</ref> but these are likely distinct mandarin hybrids,<ref name="smithsonian">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and genomic analysis of the clementine has shown it to have arisen from a cross between a sweet orange (Citrus × sinensis) and the Mediterranean willowleaf mandarin (Citrus × deliciosa).<ref name="Hybrid" /><ref name="genealogy" />

There are three types of clementines: seedless clementines, clementines (maximum of 10 seeds), and Monreal (more than 10 seeds). Clementines resemble other citrus varieties, such as the satsuma and tangerines.<ref name="fruitinfo">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Cultivation

Clementines differ from other citrus in having lower heat requirement, which means the tolerance to fruit maturity and sensitivity to unfavorable conditions during the flowering and fruit-setting period is higher. However, in regions of high total heat, the Clementine bears fruit early—only slightly later than satsuma mandarins. These regions, such as North Africa, Mediterranean basin, and California, also favor maximizing the Clementine size and quality.<ref name="Hodgson">Template:Cite book Template:Page needed</ref>Template:Page neededTemplate:Failed verification

It was introduced into Californian commercial agriculture in 1914, though it was grown at the Citrus Research Center (now part of the University of California, Riverside) as early as 1909.<ref name="Hodgson" /> Clementines lose their desirable seedless characteristic when they are cross-pollinated with other fruit. In 2006, to prevent this, growers—such as Paramount Citrus in California—threatened to sue local beekeepers to keep bees away from their crops.<ref name="Bees">Template:Cite news</ref>

Types

File:Clementines (01014)s.jpg

Seedless clementine, unpeeled and peeled

• Seedless – exists in North Africa. Seedless versions of the clementine are known as the common type (seedless or practically seedless). Common Clementines are very similar to the Monreal type; the two types are virtually identical in terms of tree specifics. The seedless Clementine tree is self-incompatible; which is why the fruit has so few or no seeds. In order to be pollinated, it needs to be cross-pollinated.<ref name="Hodgson" />Template:Page needed
• Monreal – exists in North Africa. The Monreal clementine can self-pollinate and has seeds. Monreal clementines are on average larger than the seedless variety, have a more abundant bloom and are sweeter.<ref name="Hodgson" />Template:Page needed
• Sweetclems — are typically grown in Spain and northern Africa. Unlike other Clementine varieties, they usually have 10 slices.Template:Citation needed They are specialised to be easy to peel. They have a sweet taste, as suggested by their name, but it is not overbearing and quite mild.<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref>Template:Better source needed The sweetclem has several other brand names, and can also be referred to as an easy-peeler, a clemengold, and a clemcott, amongst others.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Varieties

Spanish clementine, possibly the Fina cultivar

• Algerian, the original Rodier cultivar.<ref name="Kemp">Template:Cite news</ref>
• Fina, a Spanish cultivar originally grown on a bitter orange rootstock that gave it superb flavor, but due to disease vulnerability is now grown on a broader range of rootstocks, affecting the flavor profile.<ref name="Kemp" />
• Clemenules or Nules – A popular, seedless, easy to peel clementine with a very pleasing sweet flavor. A mutation of the Fina variety, Nules is the most widely planted clementine in Spain, where it matures from mid-November to mid to late-January. Also widely planted in California, where it matures from October to December.<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref> It produces seedless fruit that is larger than the Fina, but less sweet.<ref name="Kemp" />

• Clementine del Golfo di Taranto, a (practically) seedless Italian cultivar given Protected geographical indication (PGI) status by the European Union, produced around the Gulf of Taranto. They have a sweet flavour and an intense aroma.<ref>{{#invoke:citation/CS1|citation

• Clementine di Calabria, another Italian PGI variety, grown in the Calabria region.<ref>Template:Cite journal</ref>

Nutrition

A typical clementine contains 87% water, 12% carbohydrates, and negligible amounts of fat and protein (table). Among micronutrients, only vitamin C is in significant content (59% of the Daily Value) in a 100 gram reference serving, with all other nutrients in low amounts.Template:Cn

Potential drug interactions

A 2017 study indicated that clementine phytochemicals may interact with drugs in a manner similar to those of grapefruit.<ref name="drug-interaction">Template:Cite journal</ref> A follow-up study in 2019, however, has called these results into question. <ref>Template:Cite journal</ref>
