Thlaspi Arvense
''Thlaspi arvense'', known by the common name field pennycress, is a flowering plant in the cabbage family Brassicaceae. It is native to Eurasia, and is a common weed throughout much of North America and its home. Description ''Thlaspi arvense'' is a foetid, hairless annual plant, growing up to tall, with upright branches. The stem leaves are arrow-shaped, narrow and toothed. It blooms between May and July, with racemes or spikes of small white flowers that have 4 sepals and 4 longer petals. Later it has round, flat, winged pods with a deep apical notch, measuring across. They contain small brown-black seeds. The common name 'pennycress' is derived from the shape of the seeds looking like an old English penny. Other English common names are: stinkweed, bastard cress, fanweed, field pennycress, frenchweed and mithridate mustard. Pennycress is an annual, overwintering herb with an unpleasant odor when its leaves are squeezed. It grows up to 40 to 80 cm depending on environmental ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...

Tian Shan
The Tian Shan,, , otk, 𐰴𐰣 𐱅𐰭𐰼𐰃, , tr, Tanrı Dağı, mn, Тэнгэр уул, , ug, تەڭرىتاغ, , , kk, Тәңіртауы / Алатау, , , ky, Теңир-Тоо / Ала-Тоо, , , uz, Tyan-Shan / Tangritog‘, , also known as the Tengri Tagh or Tengir-Too, meaning the ''Mountains of Heaven'' or the ''Heavenly Mountain'', is a large system of mountain ranges located in Central Asia. The highest peak in the Tian Shan is Jengish Chokusu, at high. Its lowest point is the Turpan Depression, which is below sea level. One of the earliest historical references to these mountains may be related to the Xiongnu word ''Qilian'' ( zh, s=祁连, t=祁連, first=t, p=Qílián) – according to Tang commentator Yan Shigu, ''Qilian'' is the Xiongnu word for sky or heaven. Sima Qian in the ''Records of the Grand Historian'' mentioned ''Qilian'' in relation to the homeland of the Yuezhi and the term is believed to refer to the Tian Shan rather than the ...

Parboiled
Parboiling (or leaching) is the partial or semi boiling of food as the first step in cooking. The word is from the Old French 'parboillir' (to boil thoroughly) but by mistaken association with 'part' it has acquired its current meaning. The word is often used when referring to parboiled rice. Parboiling can also be used for removing poisonous or foul-tasting substances from foods, and to soften vegetables before roasting them. Basic technique The food items are added to boiling water and cooked until they start to soften, then removed before they are fully cooked. Parboiling is usually used to partially cook an item which will then be cooked another way such as braising, grilling, or stir-frying. Parboiling differs from blanching in that one does not cool the items using cold water or ice after removing them from the boiling water. Parboiled rice Sometimes raw rice or paddy is dehusked by using steam. This steam also partially boils the rice while dehusking. This pro ...

Glucosinolates
Glucosinolates are natural components of many pungent plants such as mustard, cabbage, and horseradish. The pungency of those plants is due to mustard oils produced from glucosinolates when the plant material is chewed, cut, or otherwise damaged. These natural chemicals most likely contribute to plant defence against pests and diseases, and impart a characteristic bitter flavor property to cruciferous vegetables. Plants with glucosinolates Glucosinolates occur as secondary metabolites of almost all plants of the order Brassicales. Ordered in the Brassicales are for example the economically important family Brassicaceae as well as Capparaceae and Caricaceae. Outside of the Brassicales, the genera '' Drypetes'' and '' Putranjiva'' in the family Putranjivaceae, are the only other known occurrence of glucosinolates. Glucosinolates occur in various edible plants such as cabbage (white cabbage, Chinese cabbage, broccoli), Brussels sprouts, watercress, horseradish, capers, and radishes wh ...

Erucic Acid
Erucic acid is a monounsaturated omega-9 fatty acid, denoted 22:1ω9. It has the chemical formula CH3(CH2)7CH=CH(CH2)11COOH. It is prevalent in wallflower seed and other plants in the family Brassicaceae, with a reported content of 20 to 54% in high erucic acid rapeseed oil and 42% in mustard oil. Erucic acid is also known as ''cis''-13-docosenoic acid and the trans isomer is known as brassidic acid. Uses Erucic acid has many of the same uses as mineral oils, but it is more readily biodegradable than some. It has limited ability to polymerize and dry for use in oil paints. Like other fatty acids, it can be converted into surfactants or lubricants, and can be used as a precursor to biodiesel fuel. Derivatives of erucic acid have many further uses, such as behenyl alcohol (CH3(CH2)21OH), a pour point depressant (enabling liquids to flow at a lower temperature), and silver behenate, for use in photography. Sources of erucic acid The name ''erucic'' means "of or pert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Use Efficiency
Water-use efficiency (WUE) refers to the ratio of water used in plant metabolism to water lost by the plant through transpiration. Two types of water-use efficiency are referred to most frequently: * photosynthetic water-use efficiency (also called instantaneous water-use efficiency), which is defined as the ratio of the rate of carbon assimilation (photosynthesis) to the rate of transpiration, and * water-use efficiency of productivity (also called integrated water-use efficiency), which is typically defined as the ratio of biomass produced to the rate of transpiration. Increases in water-use efficiency are commonly cited as a response mechanism of plants to moderate to severe soil water deficits and have been the focus of many programs that seek to increase crop tolerance to drought A drought is defined as drier than normal conditions.Douville, H., K.

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
