Tangor

Tangor is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tangor rather than just read about it. In short: The tangor (C. reticulata × C. sinensis) is a citrus fruit hybrid of the mandarin orange (Citrus reticulata) and the sweet orange (Citrus sinensis). The name "tangor" is a formation from the "tang" of tangerine and the "or" of "orange." Also called the temple orange, its thick rind is easy to peel and its bright orange pulp is sour-sweet and full-flavoured.

Key takeaways

Tangor belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tangor to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tangor from memory before moving on to harder problems.

Reference excerpt

The tangor (C. reticulata × C. sinensis) is a citrus fruit hybrid of the mandarin orange (Citrus reticulata) and the sweet orange (Citrus sinensis). The name "tangor" is a formation from the "tang" of tangerine and the "or" of "orange." Also called the temple orange, its thick rind is easy to peel and its bright orange pulp is sour-sweet and full-flavoured. The name "temple orange" is taken from the name of citrus magnate William Chase Temple.

Varieties

Tangors are purposely bred or accidental hybrids of the sweet orange (Citrus sinensis) and the mandarin (Citrus reticulata), producing several varieties.

'Clementine' (Willowleaf × unknown sweet orange) (a commercially important cultivar) 'King' ("King of Siam"; formerly Citrus nobilis) 'Tsunonozomi' (Kiyomi x Encore) 'Murcott' ("honey Murcott"; "Murcott honey orange"; "red"; "big red") 'Ortanique' (originally found in Jamaica, the name comes from the words "orange", "tangerine", and "unique"). In 1939, David Daniel Phillips was recognised by the Jamaica Agricultural Society (JAS) as the creator of the ortanique. 'Temple' (Willowleaf × unknown sweet orange) (believed to be the same as the "magnet" variety of Japan) 'Umatilla' (misnomer "Umatilla tangelo") 'Pontianak' (originally found in Indonesia, named after a provincial capital) 'Setoka' (Japan, hybrid of Murcott and Kuchinotsu No.37) 'Gonggan' (China)

Satsuma tangors 'Iyokan' (Miyagawa × unknown sweet orange) 'Miyauchi Iyo' (early-ripening Iyo mutant) 'Othani Iyo' (late-ripening Miyauchi mutant) 'Kiyomi' (Miyagawa × Trovita navel orange) 'Seto' (Sugiyama Unshiu × Trovita navel orange) 'Reikou' ((Kiyomi x Encore) x (No. 5 x Marcott))

Cultivation regions Since the 19th and early 20th centuries, tangors have been cultivated in tropical and warm temperate world regions, such as southern Japan, Florida, Caribbean islands, South Africa, and Malaysia.

Pests and diseases The 'Ortanique' variety may be attacked by aphids (Aphis gossypii), rust mite (Phyllocoptruta oleivora) or various species of scale insects and moths. The fungus Sphaeropsis tumefaciens may cause knots in twigs.

Worked examples

Example 1 — a first encounter with Tangor

Start with the simplest possible case. Write down what Tangor claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tangor before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tangor ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tangor

In research: Tangor appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tangor in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tangor is common in secondary-school and first-year university syllabi. It links to neighbouring topics Citrus hybrids, Flora of Jamaica, Fruit stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Tangor outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Tangor in simple terms?

Why does Tangor matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Tangor?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
