Beta vulgaris (beet) is a plant which is included in Betoideae subfamily in the Amaranthaceae family. It is the economically most important crop of the large order Caryophyllales. It has several cultivar groups, the sugar beet, of greatest importance to produce table sugar; the root vegetable known as the beetroot or garden beet; the leaf vegetables chard and spinach beet; and mangelwurzel, which is a fodder crop. Three subspecies are typically recognised. All cultivars fall into the subspecies Beta vulgaris subsp. vulgaris. The wild ancestor of the cultivated beets is the sea beet (Beta vulgaris subsp. maritima).
Beta vulgaris is an herbaceous biennial or, rarely, perennial plant up to 120 cm (rarely 200 cm) height, cultivated forms are mostly biennial. The roots of cultivated forms are dark red, white, or yellow and moderately to strongly swollen and fleshy (subsp. vulgaris), or brown, fibrous, sometimes swollen and woody in the wild subspecies. The stems grow erect or, in the wild forms, often procumbent, they are simple or branched in the upper part, their surface is ribbed and striate. The basal leaves have a long petiole (which may be thickened and red, white, or yellow in some cultivars). The simple leaf blade is oblanceolate to heart-shaped, dark green to dark red, slightly fleshy, usually with a prominent midrib, with entire or undulate margin, 5-20cm long on wild plants (often much larger in cultivated plants). The upper leaves are smaller, their blades are rhombic to narrowly lanceolate.
The flowers are produced in dense spike-like, basally interrupted inflorescences. Very small flowers are sitting in one- to three- (rarely eight-) flowered glomerules in the axils of short bracts, in the upper half of the inflorescence without bracts. The hermaphrodite flowers are urn-shaped, green or tinged reddish, and consist of five basally connate perianth segments (tepals), 3-5 2-3 mm, 5 stamens, and a semi-inferior ovary with 2-3 stigmas. The perianths of neighbouring flowers are often fused. Flowers are wind pollinated.
In fruit, the glomerules of flowers form connate hard clusters. The fruit (utricle) is enclosed by the leathery and incurved perianth, and is immersed in the swollen, hardened perianth base. The horizontal seed is lenticular, 2-3 mm, with red-brown, shiny seed coat. The seed contains an annular embryo and copious perisperm (feeding tissue).
The chromosome number is 2n=18.
The wild forms of Beta vulgaris are distributed in southwestern, northern and Southeast Europe along the Atlantic coasts and the Mediterranean Sea, in North Africa, Macaronesia, to Western Asia. Naturalized they occur in other continents. The plants grow at coastal cliffs, on stony and sandy beaches, in salt marshes or coastal grasslands, and in ruderal or disturbed places.
Cultivated beets are grown worldwide in regions without severe frosts. They prefer relatively cool temperatures between 15 and 19 C, leaf beets can thrive in warmer temperatures than beetroot. As descendants of coastal plants, they tolerate salty soils and drought. They grow best on pH-neutral to slightly alkaline soils containing plant nutrients and additionally Sodium and Boron.
The species description of Beta vulgaris was made in 1753 by Carl Linnaeus in "Species Plantarum", at the same time creating the genus Beta. Linnaeus regarded sea beet, chard and red beet as varieties (at that time, sugar beet and mangelwurzel had not been selected yet). In the second edition of "Species Plantarum" (1762), Linnaeus separated the sea beet as its own species, Beta maritima, and left only the cultivated beets in Beta vulgaris. Today sea beet and cultivated beets are considered as belonging to the same species, because they may hybridize and form fertile offspring. The taxonomy of the various cultivated races has a long and complicated history, they were treated at the rank of either subspecies, or convarieties or varieties. Now rankless cultivar groups are used, according to the International Code of Nomenclature for Cultivated Plants.
Beta vulgaris belongs to the subfamily Betoideae in family Amaranthaceae (s.l, including the Chenopodiaceae).
Beta vulgaris is classified into three subspecies:
Beets are a food plant for the larvae of a number of Lepidoptera species.
Spinach beet leaves are eaten as a pot herb. Young leaves of the garden beet are sometimes used similarly. The midribs of Swiss chard are eaten boiled while the whole leaf blades are eaten as spinach beet.
In some parts of Africa, the whole leaf blades are usually prepared with the midribs as one dish.
The leaves and stems of young plants are steamed briefly and eaten as a vegetable; older leaves and stems are stir-fried and have a flavour resembling taro leaves.
The usually deep-red roots of garden beet can be baked, boiled, or steamed, and often served hot as a cooked vegetable or cold as a salad vegetable. They are also pickled. Raw beets are added to salads. A large proportion of the commercial production is processed into boiled and sterilised beets or into pickles. In Eastern Europe beet soup, such as cold borsch, is a popular dish. Yellow-coloured garden beets are grown on a very small scale for home consumption.
The consumption of beets causes pink urine in some people.
Jews traditionally eat beet on Rosh Hashana (New Year). Its Aramaic name sounds like the word for "remove" or "depart"; it is eaten with a prayer "that our enemies be removed".
Beets are low in calories (about 45 kcal per 100 g) and have zero cholesterol and a minute amount of fat. Nutrition comes from the beets' vitamins, minerals, and unique plant-derived anti-oxidants.
A phytochemical compound, glycine betaine, is found in the root. Betaine lowers the chance of coronary heart disease (CHD), stroke, and peripheral vascular diseases. Beets in raw form are high in folates. Folates are essential in the synthesis of DNA within cells. Vitamin-C is found in small amounts.
The root provides B-complex vitamins including niacin (B-3), pantothenic acid (B-5), and pyridoxine (B-6), and minerals such as iron, manganese, copper, magnesium, and potassium, lowers the heart rate and regulates metabolism in the cells.
Beet greens contain vitamin C, carotenoids, flavonoid anti-oxidants, and vitamin-A.
The roots and leaves of the beet have been used in folk medicine to treat a wide variety of ailments.Ancient Romans used beetroot as a treatment for fevers and constipation, amongst other ailments. Apicius in De re coquinaria gives five recipes for soups to be given as a laxative, three of which feature the root of beet.Hippocrates advocated the use of beet leaves for binding wounds. Since Roman times, beetroot juice has been considered an aphrodisiac. From the Middle Ages, beetroot was used as a treatment for a variety of conditions, especially those relating to digestion and the blood. Platina recommended taking beetroot with garlic to nullify the effects of 'garlic-breath'.[clarification needed]
It has been suggested the pigment molecule betanin in the root of red beets may protect against oxidative stress and has been used for this purpose in Europe for centuries.
All parts of the beet plant contain oxalic acid. Beet greens and Swiss chard are both considered high oxalate foods which have been implicated on the formation of kidney stones.
Cultivars with large, brightly coloured leaves are grown for decorative purposes.
Beets are cultivated for fodder (e.g. mangelwurzel), for sugar (the sugar beet), as a leaf vegetable (chard or "Bull's Blood"), or as a root vegetable ("beetroot", "table beet", or "garden beet").
"Blood Turnip" was once a common name for beet root cultivars for the garden. Examples include: Bastian's Blood Turnip, Dewing's Early Blood Turnip, Edmand Blood Turnip, and Will's Improved Blood Turnip.
The "earthy" taste of some beetroot cultivars comes from the presence of geosmin. Researchers have not yet answered whether beets produce geosmin themselves or whether it is produced by symbiotic soil microbes living in the plant. Breeding programs can produce cultivars with low geosmin levels yielding flavours more acceptable to consumers.
Beets are one of the most boron-intensive of modern crops, a dependency possibly introduced as an evolutionary response its pre-industrial ancestor's constant exposure to sea spray; on commercial farms, a 60 tonne per hectare (26.8 ton/acre) harvest requires 600grams of elemental boron per hectare (8.6 ounces/acre) for growth. A lack of boron causes the meristem and the shoot to languish, eventually leading to heart rot.
The color of red/purple beetroot is due to a variety of betalain pigments, unlike most other red plants, such as red cabbage, which contain anthocyanin pigments. The composition of different betalain pigments can vary, resulting in strains of beetroot which are yellow or other colors in addition to the familiar deep red. Some of the betalains in beets are betanin, isobetanin, probetanin, and neobetanin (the red to violet ones are known collectively as betacyanin). Other pigments contained in beet are indicaxanthin and vulgaxanthins (yellow to orange pigments known as betaxanthins). Indicaxanthin has been shown as a powerful protective antioxidant for thalassemia and prevents the breakdown of alpha-tocopherol (Vitamin E).
Betacyanin in beetroot may cause red urine in people who are unable to break it down. This is called beeturia.
The pigments are contained in cell vacuoles. Beetroot cells are quite unstable and will 'leak' when cut, heated, or when in contact with air or sunlight. This is why red beetroots leave a purple stain. Leaving the skin on when cooking, however, will maintain the integrity of the cells and therefore minimize leakage.
The sea beet, the ancestor of modern cultivated beets, prospered along the coast of the Mediterranean Sea. Beetroot remains have been excavated in the Third dynasty Saqqara pyramid at Thebes, Egypt, and four charred beetroots were found in the Neolithic site of Aartswoud in the Netherlands though it has not been determined whether these were domesticated or wild forms of B. vulgaris. Zohary and Hopf note that beetroot is "linguistically well identified." They state the earliest written mention of the beet comes from 8th century BC Mesopotamia. The Greek Peripatetic Theophrastus later describes the beet as similar to the radish, while Aristotle also mentions the plant. Available evidence, such as that provided by Aristotle and Theophrastus, suggests the leafy varieties of the beet were grown primarily for most of its history, though these lost much of their popularity following the introduction of spinach. The ancient Romans considered beets an important health food and an aphrodisiac.
Roman and Jewish literary sources suggest that in the 1st century BC the domestic beet was represented in the Mediterranean basin primarily by leafy forms like chard and spinach beet. Zohary and Hopf also argue that it is very probable that beetroot cultivars were also grown at the time, and some Roman recipes support this. Later English and German sources show that beetroots were commonly cultivated in Medieval Europe.
Modern sugar beets date back to mid-18th century Silesia where the king of Prussia subsidised experiments aimed at processes for sugar extraction. In 1747 Andreas Marggraf isolated sugar from beetroots and found them at concentrations of 1.3-1.6%. He also demonstrated that sugar could be extracted from beets that was the same as that produced from sugarcane. His student, Franz Karl Achard, evaluated 23 varieties of mangelwurzel for sugar content and selected a local race from Halberstadt in modern-day Saxony-Anhalt, Germany. Moritz Baron von Koppy and his son further selected from this race for white, conical tubers. The selection was named 'Weie Schlesische Zuckerrbe', meaning white Silesian sugar beet, and boasted about a 6% sugar content. This selection is the progenitor of all modern sugar beets.
A royal decree led to the first factory devoted to sugar extraction from beetroots being opened in Kunern, Silesia (now Konary, Poland) in 1801. The Silesian sugar beet was soon introduced to France where Napoleon opened schools specifically for studying the plant. He also ordered that 28,000 hectares (69,000 acres) be devoted to growing the new sugar beet. This was in response to British blockades of cane sugar during the Napoleonic Wars, which ultimately stimulated the rapid growth of a European sugar beet industry. By 1840 about 5% of the world's sugar was derived from sugar beets, and by 1880 this number had risen more than tenfold to over 50%. The sugar beet was introduced to North America after 1830 with the first commercial production starting in 1879 at a farm in Alvarado, California. The sugar beet was also introduced to Chile via German settlers around 1850.
It remains a widely cultivated commercial crop for producing table sugar, in part due to subsidies scaled to keep it competitive with tropical sugar cane.
