A pumpkin is a gourd-like squash of the genus Cucurbita and the family Cucurbitaceae (which also includes gourds). It commonly refers to cultivars of any one of the species Cucurbita pepo, Cucurbita mixta, Cucurbita maxima, and Cucurbita moschata, and is native to North America. They typically have a thick, orange or yellow shell, creased from the stem to the bottom, containing the seeds and pulp. Pumpkins are widely grown for commercial use, and are used both in food and recreation. Pumpkin pie, for instance, is a traditional part of Thanksgiving meals in the United States, and pumpkins are frequently carved as decorations around Halloween. A pumpkin that has a little face carved in it and hollowed out and decorated with candles inside is known as a jack o'lantern; these are often used at Hallowe'en, for example, to decorate windows.

In Australian English, the name 'pumpkin' generally refers to the broader category called winter squash in North America.

Description[]

The word pumpkin originates from the word pepon (πέπων), which is Greek for “large melon". The French adapted this word to pompon, which the British changed to pumpion and later American colonists changed that to the word we use today, "pumpkin". The origin of pumpkins is not definitively known, although they are thought to have originated in North America. The oldest evidence, pumpkin-related seeds dating between 7000 and 5500 BC, were found in Mexico. Pumpkins are a squash-like fruit that range in size from less than 1 pound (0.45 kilograms) to over 1,000 pounds (450 kilograms).

Since some squash share the same botanical classifications as pumpkins, the names are frequently used interchangeably. In general, pumpkin stems are more rigid, prickly, and angular (with an approximate five-degree angle) than squash stems, which are generally softer, more rounded, and more flared where joined to the fruit.

Pumpkins generally weigh 9–18 lbs (4–8 kg) with the largest (of the species C. maxima) capable of reaching a weight of over 75lbs (34kg). The pumpkin varies greatly in shape, ranging from oblate to oblong. The rind is smooth and usually lightly ribbed. Although pumpkins are usually orange or yellow, some fruits are dark green, pale green, orange-yellow, white, red and gray.

Pumpkins are monoecious, having both male and female flowers on the same plant. The female flower is distinguished by the small ovary at the base of the petals. These bright and colorful flowers have extremely short life spans and may only open for as short a time as one day. The color of pumpkins is derived from the orange pigments abundant in them. The main nutrients are lutein and both alpha and beta carotene, the latter of which generates vitamin A in the body.

Taxonomy[]

Pumpkin is the fruit of the genus Cucurbita and the family Cucurbitaceae. The term "pumpkin" commonly refers to cultivars of any one of the species Cucurbita pepo, Cucurbita mixta, Cucurbita maxima, and Cucurbita moschata.

Distribution and habitation[]

Pumpkins are grown all around the world for a variety of reasons ranging from agricultural purposes (such as animal feed) to commercial and ornamental sales. Of the seven continents, only Antarctica is unable to produce pumpkins; the biggest international producers of pumpkins include the United States, Canada, Mexico, India, and China. The traditional American pumpkin is the Connecticut Field variety.

Ecology[]

Cultivation in the US[]

As one of the most popular crops in the United States, 1.5 billion pounds (680,000,000 kilograms) of pumpkins are produced each year. The top pumpkin-producing states in the U.S. include Illinois, Indiana, Ohio, Pennsylvania, and California.

According to the Illinois Department of Agriculture, 95% of the U.S. crop intended for processing is grown in Illinois. Nestlé produces 85% of the processed pumpkin in the U.S. In the fall of 2009, rain in Illinois devastated the Nestlé crop, resulting in a shortage affecting the entire country during the Thanksgiving holiday season.

Pumpkins are a warm-weather crop that is usually planted in early July. The specific conditions necessary for growing pumpkins require that soil temperatures three inches (7.62 cm) deep are at least 60 °F (15.5 °C) and soil that holds water well. Pumpkin crops may suffer if there is a lack of water or because of cold temperatures (in this case, below 65 °F (18.3 °C); frost can be detrimental), and sandy soil with poor water retention or poorly drained soils that become waterlogged after heavy rain. Pumpkins are, however, rather hardy, and even if many leaves and portions of the vine are removed or damaged, the plant can very quickly re-grow secondary vines to replace what was removed.

Pumpkins produce both a male and female flower; honeybees play a significant role in fertilization. Pumpkins have historically been pollinated by the native squash bee Peponapis pruinosa, but this bee has declined, probably due to pesticide sensitivity, and today most commercial plantings are pollinated by honeybees. One hive per acre (4,000 m² per hive) is recommended by the United States of America (US) Department of Agriculture. If there are inadequate bees for pollination, gardeners often have to hand pollinate. Inadequately pollinated pumpkins usually start growing but abort before full development. An opportunistic fungus is also sometimes blamed for abortions.

Giant pumpkins[]

The largest pumpkins are Cucurbita maxima. They were cultivated from the hubbard squash genotype, crossed with kabocha-pumpkin types by enthusiast farmers through intermittent effort since the early 19th century. As such germplasm is commercially provocative, a U.S. legal right was granted for the rounder phenotypes, levying them as constituting a variety, with the appellation Atlantic Giant. Eventually, this phenotype graduated back into the public domain, except now it had the name Atlantic Giant on its record.

Weigh-off competitions for giant pumpkins are a popular festival activity. The world record held at 460 pounds (208.65 kilograms) until 1981, when Howard Dill (of Nova Scotia) broke the record with a pumpkin near 500 pounds (226.80 kilograms). Dill patented the seeds used to grow this giant pumpkin, deeming them Dill’s Atlantic Giant seeds, and drawing growers from around the world. Dill is credited for all of the giant pumpkins today, most of which are borne from crossing and re-crossing his patented seed with other varieties. By 1994, the Giant pumpkin crossed the 1,000-pound (453.59-kilogram) mark. The current world record holder is Chris Stevens's 1,810-pound Atlantic Giant pumpkin, which in October 2010 surpassed Christy Harp's previous 2009 record of 1,725 pounds.

Uses[]

Cooking[]

Pumpkins are very versatile in their uses for cooking. Most parts of the pumpkin are edible, including the fleshy shell, the seeds, the leaves, and even the flowers. In the United States and Canada, pumpkin is a popular Halloween and Thanksgiving staple. Homemade pumpkin purée can serve the same purpose.

When ripe, the pumpkin can be boiled, baked, steamed, or roasted. In its native North America, it is a very important, traditional part of the autumn harvest, eaten mashed and making its way into soups and purees. Often, it is made into pie, various kinds of which are a traditional staple of the Canadian and American Thanksgiving holidays. In Canada, Mexico, the U.S., Europe and China, the seeds are often roasted and eaten as a snack.

Pumpkins that are still small and green may be eaten in the same way as squash or zucchini. In the Middle East, pumpkin is used for sweet dishes; a well-known sweet delicacy is called halawa yaqtin. In South Asian countries such as India, pumpkin is cooked with butter, sugar, and spices in a dish called kadu ka halwa. Pumpkin is used to make sambar in Udupi cuisine. In Guangxi province, China, the leaves of the pumpkin plant are consumed as a cooked vegetable or in soups. In Australia and New Zealand, pumpkin is often roasted in conjunction with other vegetables. In Japan, small pumpkins are served in savory dishes, including tempura. In Myanmar, pumpkins are used in both cooking and desserts (candied). The seeds are a popular sunflower seed substitute. In Thailand, small pumpkins are steamed with custard inside and served as a dessert. In Italy, it can be used with cheeses as a savory stuffing for ravioli. Also, pumpkin can be used to flavor both alcoholic and nonalcoholic beverages.

In the southwestern United States and Mexico, pumpkin and squash flowers are a popular and widely available food item. They may be used to garnish dishes, and they may be dredged in a batter then fried in oil. Pumpkin leaves are a popular vegetable in the Western and central regions of Kenya; they are called seveve, and are an ingredient of mukimo, respectively, whereas the pumpkin itself is usually boiled or steamed. The seeds are popular with children who roast them on a pan before eating them.

Extract[]

East China Normal University research on type-1 diabetic rats, published in July 2007, suggests that chemical compounds found in pumpkin promote regeneration of damaged pancreatic cells, resulting in increased bloodstream insulin levels. According to the research team leader, pumpkin extract may be "a very good product for pre-diabetic people, as well as those who already have diabetes," possibly reducing or eliminating the need for insulin injections for some type-1 diabetics. It is unknown whether pumpkin extract has any effect on diabetes mellitus type 2, as it was not the subject of the study.
