| 説明 | One remaining seed to be dispersed from this dandelion. Dandelions are very prolific and one contributing factor is that seed production is asexual so that all the progeny are identical to the parent. Dandelions produce latex that is suitable for the manufacture of rubber [see below).Taraxacum is a large genus of flowering plants in the family Asteraceae and consists of species commonly known as dandelion. They are native to Eurasia and North America, and two species, T. officinale and T. erythrospermum, are found as commonplace wild flowers worldwide. Both species are edible in their entirety. The common name dandelion from French dent-de-lion, meaning "lion's tooth") is given to members of the genus. Like other members of the Asteraceae family, they have very small flowers collected together into a composite flower head. Each single flower in a head is called a floret. Many Taraxacum species produce seeds asexually by apomixis, where the seeds are produced without pollination, resulting in offspring that are genetically identical to the parent plant.Dandelions secrete latex when the tissues are cut or broken, yet in the wild type, the latex content is low and varies greatly. Using modern cultivation methods and optimization techniques, scientists in the Fraunhofer Institute for Molecular Biology and Applied Ecology (IME) in Germany developed a cultivar that is suitable for commercial production of natural rubber. The latex produced exhibits the same quality as the natural rubber from rubber trees.[43] In collaboration with Continental Tires, IME is building a pilot facility. As of May 2014, the first prototype test tires made with blends from dandelion-rubber are scheduled to be tested on public roads over the next few years. [Wikipedia] |
