Chaerophyllum bulbosum is a species of flowering plant from the carrot family and known by several common names, including turnip-rooted chervil , tuberous-rooted chervil, bulbous chervil, and parsnip chervil. [2] It is native to Europe and Western Asia. It was a popular vegetable in the 19th century.
This is a tall annual herb with fringelike divided leaves and large umbels of white flowers. The plant is cultivated on a small scale in parts of Europe for the edible tubers, which look like a dark gray carrot with yellowish-white flesh. After the harvest they are stored for a few months under cold conditions. During storage, sugar content increases through hydrolysis of starch by amylases. [3]
Chaerophyllum bulbosum is a biennial plant. In the first year, its rosette of leaves produces large amounts of starch, which are stored in the taproot to provide energy for the plant to flower in the second year. In the second year, it grows up to a height of 70 cm to > 2 m. [4]
The stem is smooth with nodes at intervals. It is hairy around the base just above the ground and may show scattered red spots. Additionally, the lower stem is often blue-rimmed.
Subsequent leaves are alternate (with a single leaf attached to a node), spirally arranged, and pinnately compound, with leaf bases sheathing the stem. As the plant grows, the bases of the seed leaves, near the taproot, are pushed apart. The stem, located just above the ground, is compressed and the internodes are not distinct. When the seed stalk elongates for flowering, the tip of the stem narrows and becomes pointed, and the stem extends upward to become a highly branched inflorescence.
Characteristic of an Apiaceae plant, Chaerophyllum bulbosum individuals produce 10 - 200 umbels. A total of 1,000 - 36,000 flowers are produced per plant. The flowers are protandrous. The styles only elongate after pollen is shed, which prevents selfing almost completely under wild, optimal pollination conditions. Chaerophyllum bulbosum is an andromonoecious plant, which means that the hermaphrodite and male flowers occur on the same plant. The sex ratio between functionally male and hermaphrodite flowers is about 80% to 20%. [4]
Native, wild populations are distributed in Europe from Ukraine to France and from Sweden to Italy. In France and Germany, wild populations can be found in the Rhine and the Weser River basins. It can also be found in Western and central Asia as in Turkey and Caucasus. In the wild, tuberous-rooted chervil grows in dense populations, mainly along river banks. Seeds are dispersed by hydrochory. [5]
The plant has been grown since the Middle Ages but only survived as a garden crop in France without any named varieties. However, the first named cultivar in modern times seems to have been developed in France, named "Altan" (1986), followed by new cultivars "Véga" and "M4.10." The new varieties are mainly characterized by low seed embryo dormancy. [6] [7]
It is otherwise used in cuisine for flavoring or cooked like other root vegetables. Much of the flavor comes from the skin of the tuber. [8] [9] The aroma intensifies the longer the plant is stored. Eaten raw, the taste is somewhat sharp like radish, but the cooked tuber gives a subtle taste of potatoes and chestnuts with a slightly pungent taste of celery and parsnip. [10] C. bulbosum roots are high in fiber and have the same starchy quality as potatoes. They contain vitamins B and C and mineral salts. [8]
Tuberous-rooted chervil (Chaerophyllum bulbosum) is native to middle- and south-eastern-Europe. [6] During the 1580s, tubers of tuberous-rooted chervil were found at the local market in Wien. In 1846, the tubers arrived in France. [11] 16 years later, the tubers became even more prominent due to Phytophthora infestans, late blight of potatoes, and had been increasingly cultivated as a substitute for potatoes. At the end of the 20th century breeding programs focused on this alternative crop mainly due to its delicate flavor. Through breeding achievements of French scientists, this alternative crop gained agricultural importance in regions like Loire Valley (France) and the north of Brittany. [6] [12]
The cultivation is similar to carrots and parsnips. An adequate site for cultivation is characterized by light and fertile soils. [13] The soil should be moderately moist. Cultivation period is from 9 up to 10 months. [14] The seeds require exposure to cold temperatures (vernalization) to break dormancy in spring. The crop cultivation starts therefore in the autumn. The dormancy ends with at least 8 weeks of continuous humidity and temperatures below 5 °C. After stratification, germination is at optimum with a temperature range between 5 and 10 °C. At temperatures above 25 to 30 °C significant germination inhibition occurs. [15] Sowing is done directly, without any seedling cultivation, from September to November. Distance between rows is usually from 20 up to 25 cm with a distance of 4 to 6 cm between seeds. [16] In the first year of growth, after sprouting in spring, the tuber develops with a leaf rosette just above ground. Voles are a common pest for this crop in the field. [17]
Harvest
Root maturity is reached when leaves turn yellow in June. The main harvest time starts in July and lasts until September. Due to the requirement of a dormancy period, it is almost mandatory to sow the seeds directly after harvest for the upcoming season. Because of this, and due to the low yield and poor germination of the seeds, Chaerophyllum bulbosum has hardly spread in commercial cultivation. [16]
Propagation
Sexual propagation through saving seeds, after harvest of the roots, is the main method of propagation. The seeds are short-lived, which means that the seeds lose their vitality easily (especially in dry seed packets); therefore, fresh seeds should be used every year. Keeping the seeds in cool and slightly damp sand might help sustain their vitality. [9]
Pollinators for Chaerophyllum bulbosum includes flies and beetles. [17]
Diseases
Similar diseases as for carrots and parsnip and other Apiaceae can occur for tuberous-rooted chervil. These are mainly the carrot fly, storage decay and root aphids. Furthermore, it can be host for other aphids, erysiphe heraclei or celery mosaic virus. [18]
Apiaceae or Umbelliferae is a family of mostly aromatic flowering plants named after the type genus Apium, and commonly known as the celery, carrot or parsley family, or simply as umbellifers. It is the 16th-largest family of flowering plants, with more than 3,800 species in about 446 genera, including such well-known, and economically important plants as ajwain, angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, lovage, cow parsley, parsley, parsnip and sea holly, as well as silphium, a plant whose exact identity is unclear and it may be extinct.
Chervil, sometimes called French parsley or garden chervil, is a delicate annual herb related to parsley. It was formerly called myrhis due to its volatile oil with an aroma similar to the resinous substance myrrh. It is commonly used to season mild-flavoured dishes and is a constituent of the French herb mixture fines herbes.
Root vegetables are underground plant parts eaten by humans as food. In agricultural and culinary terminology, the term applies to true roots such as taproots and tuberous roots as well as non-roots such as bulbs, corms, rhizomes, and stem tubers.
The parsnip is a root vegetable closely related to carrot and parsley, all belonging to the flowering plant family Apiaceae. It is a biennial plant usually grown as an annual. Its long taproot has cream-colored skin and flesh, and, left in the ground to mature, becomes sweeter in flavor after winter frosts. In its first growing season, the plant has a rosette of pinnate, mid-green leaves. If unharvested, it produces a flowering stem topped by an umbel of small yellow flowers in its second growing season, later producing pale brown, flat, winged seeds. By this time, the stem has become woody, and the tap root inedible. Precautions should be taken when handling the stems and foliage, as parsnip sap can cause a skin rash or even blindness if exposed to sunlight after handling.
Pseudopodospermum hispanicum, commonly known as black salsify or Spanish salsify, also known as black oyster plant, serpent root, viper's herb, viper's grass or simply scorzonera, is a perennial species of plant in the sunflower family (Asteraceae), cultivated as a root vegetable in the same way as purple salsify, also in the sunflower family. It is native to Southern Europe and cultivated as a crop in Southern and Central Europe. It grows on nutrient poor soils, dry pasture, rocky areas, in thickets and on limy or marly soils of temperate zones.
Oxalis tuberosa is a perennial herbaceous plant that overwinters as underground stem tubers. These tubers are known as uqa in Quechua, oca in Spanish, yams in New Zealand and a number of other alternative names. The plant was brought into cultivation in the central and southern Andes for its tubers, which are used as a root vegetable. The plant is not known in the wild, but populations of wild Oxalis species that bear smaller tubers are known from four areas of the central Andean region. Oca was introduced to Europe in 1830 as a competitor to the potato, and to New Zealand as early as 1860.
Tragopogon porrifolius is a plant cultivated for its ornamental flower and edible root. It also grows wild in many places and is one of the most widely known species of the salsify genus, Tragopogon. It is commonly known as purple or common salsify, oyster plant, vegetable oyster, Jerusalem star, Jack go to bed, or simply salsify.
Arracacia xanthorrhiza is a root vegetable that originates in the Andes, whose starchy taproot is a popular food item across South America where it is a major commercial crop.
Ullucus is a genus of flowering plants in the family Basellaceae, with one species, Ullucus tuberosus, a plant grown primarily as a root vegetable, secondarily as a leaf vegetable. The name ulluco is derived from the Quechua word ulluku, but depending on the region, it has many different names. These include illaco, melloco, chungua or ruba, olluco or papalisa, or ulluma.
The yacón is a species of daisy traditionally grown in the northern and central Andes from Colombia to northern Argentina for its crisp, sweet-tasting, tuberous roots. Their texture and flavour are very similar to jícama, mainly differing in that yacón has some slightly sweet, resinous, and floral undertones to its flavour, probably due to the presence of inulin, which produces the sweet taste of the roots of elecampane, as well. Another name for yacón is Peruvian ground apple, possibly from the French name of potato, pomme de terre. The tuber is composed mostly of water and various polysaccharides.
Lathyrus tuberosus is a small, climbing perennial plant, native in moist temperate parts of Europe and Western Asia. The plant is a trailer or weak climber, supported by tendrils, growing to 1.2 m tall. The leaves are pinnate, with two leaflets and a branched twining tendril at the apex of the petiole. Its flowers are hermaphroditic, pollinated by bees. The plants can also spread vegetatively from the root system.
Conopodium majus is a perennial herbaceous flowering plant in the celery family Apiaceae. Its underground part resembles a chestnut and is sometimes eaten as a wild or cultivated root vegetable. The plant has many English names variously including kippernut, cipernut, arnut, jarnut, hawknut, earth chestnut, groundnut, and earthnut. From its popularity with pigs come the names pignut, hognut, and more indirectly Saint Anthony's nut, for Anthony the Great or Anthony of Padua, both patron saints of swineherds.
Coleus esculentus, synonym Plectranthus esculentus, also known as the kaffir potato or Livingstone potato, is a species of plant in the dicot family Lamiaceae. It is indigenous to Africa, where it is grown for its edible tubers. It is more difficult to cultivate than Coleus rotundifolius, but able to give greater yields. Although the crop is similar to a potato, it is from the mint family, but it is still quite nutritious and useful. This crop can benefit many subsistence farmers since it is native, easy to grow, enjoying growing popularity in the market, and quite nutritious.
Pachyrhizus erosus, commonly known as jícama or Mexican turnip, is a native Mexican vine, although the name jícama most commonly refers to the plant's edible tuberous root. It is in the pea family (Fabaceae). Pachyrhizus tuberosus and Pachyrhizus ahipa are the other two cultivated species in the genus. The naming of this group of edible plants can sometimes be confusing, with much overlap of similar or the same common names.
Vegetables are parts of plants that are consumed by humans or other animals as food. The original meaning is still commonly used and is applied to plants collectively to refer to all edible plant matter, including the flowers, fruits, stems, leaves, roots, and seeds. An alternative definition of the term is applied somewhat arbitrarily, often by culinary and cultural tradition. It may exclude foods derived from some plants that are fruits, flowers, nuts, and cereal grains, but include savoury fruits such as tomatoes and courgettes, flowers such as broccoli, and seeds such as pulses.
The carrot is a root vegetable, typically orange in color, though heirloom variants including purple, black, red, white, and yellow cultivars exist, all of which are domesticated forms of the wild carrot, Daucus carota, native to Europe and Southwestern Asia. The plant probably originated in Iran and was originally cultivated for its leaves and seeds. The most commonly eaten part of the plant is the taproot, although the stems and leaves are also eaten. The domestic carrot has been selectively bred for its enlarged, more palatable, less woody-textured taproot. Carrots are commonly consumed raw or cooked in various cuisines.
Chaerophyllum is a genus of flowering plant in the family Apiaceae, with 35 species native to Europe, Asia, North America, and northern Africa. It includes the cultivated root vegetable Chaerophyllum bulbosum.
Olericulture is the science of vegetable growing, dealing with the culture of non-woody (herbaceous) plants for food.
Common scab is a plant disease of root and tuber crops caused by a small number of Streptomyces species, specifically S. scabies, S. acidiscabies, S. turgidiscabies and others. Common scab mainly affects potato, but can also cause disease on radish, parsnip, beet, and carrot. This plant disease is found wherever these vegetables are grown.
Pachyrhizus ahipa, also called the ahipa or Andean yam bean, is a tuberous root-producing legume, which is distributed mainly in the Andean region.
