In the 1930s, Russia experimented with making rubber from dandelion roots but abandoned the project after the war. to palm-oil plantations in order to produce biofuel, and labor costs reduce the profitability of Hevea brasiliensis plantations, as each tree must be manually tapped in order to harvest its latex. When compared to natural rubber, Russian Dandelion has a much greater geographical distribution. The Russian dandelion, Taraxacum kok-saghyz, was discovered in Eastern Kazakhstan in 1931.The plant has the yellow flowers characteristic of the dandelion genus, but the roots contain a higher percentage of rubber than the familiar species of dandelion … Share Facebook Twitter Can Dandelions Bounce Back? URL 1, URL 2). Guayule and Russian Dandelion as Alternative Sources of Natural Rubber. Although the rubber polymer of TKS is longer than that of Hevea, its rubber productivity per acre is lower [1,7,8]. Each flower head may be approximately one inch in diameter and be made up for 50 to 90 florets. [6] Flowers are hermaphrodite, insect-pollinated (entomophilous) and are on stalks that reach about a foot in height. Russian dandelion is a close relative of our native dandelion. The draft TKS genome assembly has a length of 1.29 Gb, containing 46 731 … “We are making […] crosses between the Russian dandelion and the common dandelion using those modern DNA profiling technologies,” says KeyGene CEO Arjen Van Tunen. The Soviet Union cultivated Taraxacum kok-saghyz, together with Taraxacum hybernum [ru] and Scorzonera tau-saghyz, on a large scale between 1931 and 1950—notably during World War II—as an emergency source of rubber when supplies of rubber from Hevea brasiliensis in Southeast Asia were threatened. SPEDIZIONE GRATUITA su ordini idonei Dandelion Rubber from Continental Nominated as One of the Top 3 Projects at the GreenTec Awards 2014. Two plant species have received considerable attention as potential alternative sources of natural rubber: the Mexican shrub Guayule (Parthenium argentatum Gray) and the Russian dandelion (Taraxacum koksaghyz). Close Relatives: Common dandelion Uses and Markets: The root of the Russian dandelion is a source of a high quality latex, used in making rubber, that is comparable to the latex produced by the Hevea brasiliensis rubber tree. Despite its potential to help maintain a stable worldwide rubber supply, little is known about genetic variation in this species. [8][10][2], Inulin produced by T. kok-saghyz is a sugar that could be used in non-food applications or be turned into bioethanol through fermentation. Natural rubber and the Russian dandelion genome Brandon S. Gaut. It flowers from May to June producing seeds which mature from June to July. Circular Economy. But none seem to produce as much as the Russian dandelion or contain as strong a rubber. The Russian dandelion, Taraxacum kok-saghyz (TKS), is a perennial species native to Central Asia that produces high quality, natural rubber. The cultivation of dandelion also offers the opportunity to increase the diversity of cultivation on domestic fields. T. koksaghyz was discovered in 1931 in the framework of a program to make the USSR self-sufficient in strategic materials, including natural rubber. Nearly all this rubber currently has its origins in rubber tree plantations in Asia. Synthetic rubber is used in the production of countless products, making it an important global resource. Close Relatives: Common dandelion Uses and Markets: The root of the Russian dandelion is a source of a high quality latex, used in making rubber, that is comparable to the latex produced by the Hevea brasiliensis rubber tree. Although natural rubber is found in at least 2,500 plant varieties, most of these are unsuitable for the large-scale production of good quality rubber.

Unlike other rubber-bearing plants, this dandelion species also contains inulin, a food additive … Another rare dandelion that we’ve taken under our wing. [1] Another species, a triploid apomict that also has horned bracts and produces rubber, T. brevicorniculatum Korol. The dandelion rubber used is cultivated, extracted and processed in Germany. Now, dandelion rubber proponents say long-term concerns about prices , sustainability and labor availability are strong enough to develop dandelion rubber seriously. The Russian dandelion, native to Kazakhstan, was cultivated in the Soviet Union as a domestic source of rubber in the 1930s to 50s, and after World War II to help combat the rubber shortage in Europe. [4][2] In May 2019 German tire-maker Continental AG announced it was about to begin production of the "first bicycle tyre made with sustainable rubber from dandelions", which it intended to grow on the grounds of its own manufacturing plants, avoiding several of the traditional issues with H. brasiliensis latex—from the long lead-time between planting and cultivating (only six months for the dandelion, rather than seven years for the rubber tree) and volatile prices of the product due to the long transport-distances between places where the rubber can be grown and the company's factories. The U.S., U.K., Germany, Sweden and Spain also cultivated TKS during WWII when Southeast Asian rubber supplies from Hevea brasiliensis were threatened. Some polymers exist naturally and others are produced in laboratories and f… Russian Dandelion and Guayule have almost identical qualities compared to natural rubber harvested from the Hevea tree, which is currently the primary source for the natural rubber used in tires. Because of the invention of synthetic rubber and the higher yields of rubber per hectare from the rubber tree, the dandelion was mostly forgotten. (2007).

Also known as Kazakh dandelion or rubber root, Russian dandelion resembles the familiar dandelion, but the leaves are thicker and have a grayish tint. Some polymers exist naturally and others are produced in laboratories and factories.. A polymer is a chemical compound with large molecules made of many smaller molecules of the same kind. This blight may spread to the Hevea brasiliensis trees in Southeast Asia, which are genetically very similar to each other and to those of South America. More frequent updates are provided on the following pages: Please send me the ecSeq newsletter. The use of Russian dandelions to produce rubber could soon become very important. Flowers are hermaphroditic. The Russian dandelion (Taraxacum kok-saghyz, TKS), which has lately been called the rubber dandelion, has been studied as a major alternative crop since World War II, because it can produce natural rubber of good quality [1,4]. Taraxacum kok-saghyz, often abbreviated as TKS and commonly referred to as the Kazakh dandelion, rubber root, or Russian dandelion, is a species of dandelion native to Kazakhstan, Kirghizia and Uzbekistan, that is notable for its production of high quality rubber. In the 1930’s, Russia produced ~30% of their domestic rubber from 67,000 hectares of this plant. [1] One threat to Hevea brasiliensis rubber production is the South American Leaf Blight (SALB), which has afflicted conventional rubber production in South America since 1934. The Russian dandelion has the potential to become an excellent source of commercial rubber. To date several European tire manufacturers produced durable tires from dandelion rubber as proof of this concept (e.g. The U.S., U.K., Germany, Sweden and Spain also cultivated TKS during WWII when Southeast Asian rubber supplies from Hevea brasiliensis were threatened. URL 1, URL 2). Inulin is an interesting by-product of Tks (Van Beilen and Poirier, 2007a). Critical Reviews in Biotechnology: Vol. Natural rubber is a valuable commodity because it has useful properties that synthetic rubber lacks.
