Extensive Definition

Watermelon (Citrullus lanatus (Thunb.) Matsum & Nakai, family Cucurbitaceae) refers to both fruit and plant of a vine-like (climber and trailer) herb originally from southern Africa and one of the most common types of melon. This flowering plant produces a special type of fruit known by botanists as a pepo, which has a thick rind (exocarp) and fleshy center (mesocarp and endocarp); pepos are derived from an inferior ovary and are characteristic of the Cucurbitaceae. The watermelon fruit, loosely considered a type of melon (although not in the genus Cucumis), has a smooth exterior rind (green and yellow) and a juicy, sweet, usually red or yellow, but sometimes orange, interior flesh. The flesh consists of highly developed placental tissue within the fruit.

History

David Livingstone,an explorer of Africa, described watermelon as abundant in the Kalahari desert, where it is believed to have originated. There, the ancestral melon grows wild and is known as the Tsamma melon (Citrullus lanatus var tastius). It is recognizable by its pinnatifid leaves and prolific fruit, up to 100 melons on a single vine. For this reason it is a popular source of water in the diet of the indigenous people. The flesh is similar to the rind of a watermelon and is often known as citron melon (distinct from the actual citron, of the citrus family); it is used for making jam and other preserves, and because of its high content of pectin is popular as a constituent of jams, jellies, and other gelled preserves. It has established itself in the wild in Baja California.
It is not known when the plant was first cultivated, but Zohary and Hopf note evidence of its cultivation in the Nile Valley from at least as early as the second millennium BC. Finds of the characteristically large seed are reported in Twelfth dynasty sites; numerous watermelon seeds were recovered from the tomb of Pharaoh Tutankhamun.
By the 10th century AD, watermelons were being cultivated in China, which is today the world's single largest watermelon producer. By the 13th century, Moorish invaders had introduced the fruit to Europe; and, according to John Mariani's The Dictionary of American Food and Drink, "watermelon" made its first appearance in an English dictionary in 1615.
In Vietnam, legend holds that watermelon was discovered in Vietnam long before it reached China, in the era of the Hùng Kings. According to legend, watermelon was discovered by Prince Mai An Tiêm, an adopted son of the 11th Hùng King. When he was exiled unjustly to an island, he was told that if he could survive for six months, he would be allowed to return. When he prayed for guidance, a bird flew past and dropped a seed. He cultivated the seed and called its fruit "dưa tây" or western melon, because the birds who ate it flew from the west. When the Chinese took over Vietnam in about 110 BC, they called the melons "dưa hảo" (good melon) or "dưa hấu". "dưa Tây", "dưa hảo", "dưa hấu" -- all words for "watermelon". An Tiêm's island is now a peninsula in the suburban district of Nga Sơn.
Museums Online South Africa list watermelons as having been introduced to North American Indians in the 1500s. Early French explorers found Native Americans cultivating the fruit in the Mississippi Valley. Many sources list the watermelon as being introduced in Massachusetts as early as 1629. Southern food historian John Egerton has said he believes African slaves helped introduce the watermelon to the United States. Texas Agricultural Extension horticulturalist Jerry Parsons, Ph.D., lists African slaves and European colonists as having distributed watermelons to many areas of the world. Parsons also mentions the crop being farmed by Native Americans in Florida (by 1664) and the Colorado River area (by 1799). Other early watermelon sightings include the Midwestern states (1673), Connecticut (1747), and the Illiana region (1822).
Until the 1940s, however, it was hard to find watermelons in good condition at grocery stores. Melon lovers had to grow their own, which tended not to keep for long, purchase them from local grocers supplied by truck farmers, or purchase them from roadside produce stands. Now they can be found in most local grocery stores, and if preferred in slices or whole, with seeds or without.
Then Charles Fredric Andrus, a horticulturist at the USDA Vegetable Breeding Laboratory in Charleston, South Carolina, set out to produce a disease-resistant and wilt-resistant watermelon. The result was "that gray melon from Charleston." Its oblong shape and hard rind made it easy to stack and ship. Its adaptability meant it could be grown over a wide geographical area. It produced high yields and was resistant to the most serious watermelon diseases: anthracnose and fusarium wilt. Today, farmers in approximately 44 states in the U.S. grow watermelon commercially, and almost all these varieties have some Charleston Gray in their lineage. Georgia, Florida, Texas, California and Arizona are the USA's largest watermelon producers.
This now-common watermelon is large enough that groceries often sell half or quarter melons. There are also some smaller, spherical varieties of watermelon, both red- and yellow-fleshed, sometimes called "icebox melons."

Culture

For commercial plantings, one beehive per acre (over 9,000 m² per hive) is the minimum recommendation by the US Department of Agriculture for pollination of conventional, seeded varieties. Because seedless hybrids have sterile pollen, pollinizer rows of varieties with viable pollen must also be planted. Since the supply of viable pollen is reduced and pollination is much more critical in producing the seedless variety, the recommended number of hives per acre, or pollinator density, increases to three hives per acre (1,300 m² per hive).
In Japan, farmers of the Zentsuji region found a way to grow cubic watermelons, by growing the fruits in glass boxes and letting them naturally assume the shape of the receptacle. The square shape is designed to make the melons easier to stack and store, but the square watermelons are often more than double the price of normal ones. Pyramid shaped watermelons have also been developed.

Seedless watermelons

Although so-called "seedless" watermelons have far fewer seeds than the seeded varieties, they generally contain at least a few soft, pale seeds. They are the product of crossing a female tetraploid plant (itself the product of genetic manipulation, using colchicine) with diploid pollen. The resulting triploid plant is sterile, but will produce the seedless fruit if pollenized by a diploid plant. For this reason, commercially available seedless watermelon seeds actually contain two varieties of seeds; that of the triploid seedless plant itself (recognizable because the seed is larger), and the diploid plant which is needed to pollenize the triploid. Unless both plant types are grown in the same vicinity, no seedless fruit will result. This system for growing seedless watermelons was first developed by H. Kihara in Japan and subsequently improved by O J Eigsti in partnership with Kihara. This scientific relationship was begun at the Third International Genetics Congress, held in Stockholm, Sweden in 1948.
Their collaboration lasted for over 20 years until Kihara died in 1986. Eigsti (who was a professor at Goshen College in Goshen, IN) developed a tetraploid hybrid in the 1950s which became the gold standard for all seedless watermelons developed since then. In 1986, Eigsti's company was reorganized and a joint venture (American Sunmelon) was entered into with SunWorld International and in the ensuing eleven years seedless watermelon became a staple in supermarkets around the world. In 1998, Eigsti's tetraploid hybrid along with all of the assets of American Sunmelon were sold to Syngenta, the seed producing arm of Novartis A.G.

As food and drink

Fresh watermelon may be eaten in a variety of ways and is also often used to flavor summer drinks and smoothies.
A one-cup serving of watermelon will provide around 48 Calories. Watermelon is an excellent source of vitamin C and vitamin A, with one serving containing 14.59 mg of vitamin C and 556.32 IU of vitamin A. Watermelon also provides significant amounts of vitamin B6 and vitamin B1, as well as the minerals potassium and magnesium. Pink watermelon is also a source of the potent carotenoid antioxidant, lycopene. The amino acid citrulline was first extracted from watermelon and analysed. Watermelons contain a significant amount of citrulline and after consumption of several kg an elevated concentration is measured in the blood plasma, this could be mistaken for citrullinaemia or other urea cycle disorder. Grilled watermelon, known as watermelon steak due to its visual similarity to raw steak, has started to become a popular item in restaurants.
Watermelon rinds are also edible, and sometimes used as a vegetable. In China, they are stir-fried, stewed, or more often pickled. When stir-fried, the de-skinned and de-fruited rind is cooked with olive oil, garlic, chili peppers, scallions, sugar and rum (and provides a great way to utilize the whole watermelon). Pickled watermelon rind is also commonly consumed in the Southern US, Russia, Ukraine, and Romania.
Watermelon seeds are rich in fat and protein, and are widely eaten as a snack, added to other dishes, or used as an oilseed. Specialized varieties are grown which have little watery flesh but concentrate their energy into seed production. In China watermelon seeds are one of the most common snack foods, popular especially with women, competing with sunflower seeds, and sold roasted and seasoned. In West Africa, they are pressed for oil, and are popular in egusi soup and other dishes. There can be some confusion between seed-specialized watermelon varieties and the colocynth, a closely-related species with which they share many characteristics, uses, and similar or identical names.
Watermelon is 92 percent water by weight. Throughout the western world, one may also find an alcoholic novelty known as a hard watermelon, or a watermelon that has been enhanced with an alcoholic beverage. This process involves boring a hole into the watermelon, then pouring the liquor inside and allowing it to mix with the flesh of the fruit. The watermelon is then cut and served as normal.
Watermelon is also mildly diuretic.

Varieties

  • Yellow Watermelon: variety of watermelon that has a yellow colored flesh. This particular type of watermelon has been described as "sweeter" and more "honey" flavored than the more popular red flesh watermelon.
  • Orangeglo: This variety has a very sweet orange pulp, and is a large oblong fruit weighing 9-14kg (20-30 pounds). It has a light green rind with jagged dark green stripes. It takes about 90-100 days from planting to harvest.
  • The Moon and Stars variety of watermelon has been around since at least the 1930s. The rind is purple/black and has many small yellow circles (stars) and one or two large yellow circles (moon). The melon weighs 9-23kg (20-50 pounds). The flesh is pink or red and has brown seeds. The foliage is also spotted. The time from planting to harvest is about 90 days.
  • Cream of Saskatchewan: This variety consists of small round fruits, around 25cm (10 inches) in diameter. It has a quite thin, light green with dark green striped rind, with sweet white flesh and black seeds. It can grow well in cool climates. It was originally brought to Saskatchewan, Canada by Russian immigrants. These melons take 80-85 days from planting to harvest.
  • Melitopolski: This variety has small round fruits roughly 28-30cm (11-12 inches) in diameter. It is an early ripening variety that originated from the Volga River region of Russia, an area known for cultivation of watermelons. The Melitopolski watermelons are seen piled high by vendors in Moscow in summer. This variety takes around 95 days from planting to harvest.
