Ponderosa lemon, more cold-sensitive than true lemons, the fruit are thick-skinned and very large. Genetic analysis showed it to be a complex hybrid of citron and pomelo. [51] Rough lemon, a citron-mandarin cross, cold-hardy and often used as a citrus rootstock [51] Sweet lemons or sweet limes, a mixed group including the lumia (pear lemon ...
The fruit contains 12 segments and about 30 seeds. The natsumikan tree is believed to be genetically derived from the pomelo (Citrus maxima). Calamondin Calamansi × Citrofortunella mitis: Calamansi, also known as calamondin, Philippine lime, or Philippine lemon, is an economically important citrus hybrid predominantly cultivated in the ...
Lemon: "true" lemons derive from one common hybrid ancestor, having diverged by mutation. The original lemon was a hybrid between a male citron and a female sour orange, itself a pomelo/pure-mandarin hybrid; citrons contribute half of the genome, while the other half is divided between pomelo and mandarin.
Lemons are hybrids of sour oranges and citrons, but they aren't man-made. The hybridization happened thousands of years ago naturally, with bees carrying the pollen between sour oranges to citrons.
According to the UN Food and Agriculture Organization, world production of all citrus fruits in 2016 was 124 million tonnes, with about half of this production as oranges. [37] At US $15.2 billion equivalent in 2018, citrus trade [ 38 ] makes up nearly half of the world fruit trade, which was US$32.1 billion that year. [ 39 ]
Ponderosa lemon also has larger than average citrus flowers, and bears fruit throughout the year. When grown as an ornamental, it requires pruning to control the shape, and may be trained as a bush or tree. Ponderosa lemon is less cold-hardy than a true lemon. [5] It bears medium to large fruit with a thick and bumpy rind.
The citron (Citrus medica), historically cedrate, [4] is a large fragrant citrus fruit with a thick rind.It is said to resemble a 'huge, rough lemon'. [5] It is one of the original citrus fruits from which all other citrus types developed through natural hybrid speciation or artificial hybridization. [6]
The fruit is large, 15–25 cm (6–10 in) in diameter, [5] usually weighing 1–2 kilograms (2–4 pounds). It has a thicker rind than a grapefruit, and is divided into 11 to 18 segments. The flesh tastes like mild grapefruit, with a little of its common bitterness (the grapefruit is a hybrid of the pomelo and the orange).
