Hordeum Jubatum
''Hordeum jubatum'', with common names foxtail barley, bobtail barley, squirreltail barley, and intermediate barley, is a perennial plant species in the grass family Poaceae. It occurs wild mainly in northern North America and adjacent northeastern Siberia. However, as it escaped often from gardens it can be found worldwide in areas with temperate to warm climates, and is considered a weed in many countries. The species is a polyploid and originated via hybridization of an East Asian ''Hordeum'' species with a close but extinct relative of Californian '' H. brachyantherum''. It is grown as an ornamental plant for its attractive inflorescences and when done flowering for its inflorescence. Properties Foxtail barley (''Hordeum jubatum'') propagates by seed. It is known for its ability to tolerate saline soils but is capable of productive growth on soil types ranging from loamy to clayey soils with pH's of 6.4 to 9.5. The upper limit of soil NaCl for productive growth and developme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné 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". 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 the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hordeum Vulgare
Barley (''Hordeum vulgare''), a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains, particularly in Eurasia as early as 10,000 years ago. Globally 70% of barley production is used as animal fodder, while 30% as a source of fermentable material for beer and certain distilled beverages, and as a component of various foods. It is used in soups and stews, and in barley bread of various cultures. Barley grains are commonly made into malt in a traditional and ancient method of preparation. In 2017, barley was ranked fourth among grains in quantity produced () behind maize, rice and wheat. Etymology The Old English word for barley was ', which traces back to Proto-Indo-European and is cognate to the Latin word ' "flour" (''see corresponding entries''). The direct ancestor of modern English ''barley'' in Old English was the derived adjective ''bærlic'', meaning "of barley". The first citation of th ...

Ramah Navajo
The Ramah Navajo Indian Reservation ( nv, Tł'ohchiní}) is a non-contiguous section of the Navajo Nation lying in parts of west-central Cibola and southern McKinley counties in New Mexico, United States, just east and southeast of the Zuni Indian Reservation. It has a land area of 230.675 sq mi (597.445 km²), over 95 percent of which is designated as off-reservation trust land. According to the 2000 census, the resident population is 2,167 persons. The Ramah Reservation's land area is less than one percent of the Navajo Nation's total area. Although part of the Navajo Nation, the Ramah Navajo Indian Reservation has had an independent history from that of the other Navajo lands. The Ramah Navajo have been recorded in this area of New Mexico since 1540, when they came to the aid of the Zuni in their defense against the Spanish conquistador Francisco Vásquez de Coronado. In the years from 1868 through the 1960s, the Ramah Navajo acted independently of the Navajo Nation. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iroquois
The Iroquois ( or ), officially the Haudenosaunee ( meaning "people of the longhouse"), are an Iroquoian-speaking confederacy of First Nations peoples in northeast North America/ Turtle Island. They were known during the colonial years to the French as the Iroquois League, and later as the Iroquois Confederacy. The English called them the Five Nations, comprising the Mohawk, Oneida, Onondaga, Cayuga, and Seneca (listed geographically from east to west). After 1722, the Iroquoian-speaking Tuscarora people from the southeast were accepted into the confederacy, which became known as the Six Nations. The Confederacy came about as a result of the Great Law of Peace, said to have been composed by Deganawidah the Great Peacemaker, Hiawatha, and Jigonsaseh the Mother of Nations. For nearly 200 years, the Six Nations/Haudenosaunee Confederacy were a powerful factor in North American colonial policy, with some scholars arguing for the concept of the Middle Ground, in that Europe ...

Yucca
''Yucca'' is a genus of perennial shrubs and trees in the family Asparagaceae, subfamily Agavoideae. Its 40–50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers. They are native to the hot and dry (arid) parts of the Americas and the Caribbean. Early reports of the species were confused with the cassava (''Manihot esculenta''). Consequently, Linnaeus mistakenly derived the generic name from the Taíno word for the latter, ''yuca''. The Aztecs living in Mexico since before the Spanish arrival, in Nahuatl, call the local yucca species (''Yucca gigantea'') , which gave the Spanish . is also used for ''Yucca filifera''. Distribution The natural distribution range of the genus ''Yucca'' (49 species and 24 subspecies) covers a vast area of the Americas. The genus is represented throughout Mexico and extends into Guatemala (''Yucca guatemalensis''). It also extends to the north through Baja Cali ...

Kawaiisu
The Kawaiisu (pronounced: ″ka-wai-ah-soo″) are a Native Californian ethnic group in the United States who live in the Tehachapi Valley and to the north across the Tehachapi Pass in the southern Sierra Nevada, toward Lake Isabella and Walker Pass. Historically, the Kawaiisu also traveled eastward on food-gathering trips to areas in the northern Mojave Desert, to the north and northeast of the Antelope Valley, Searles Valley, as far east as the Panamint Valley, the Panamint Mountains, and the western edge of Death Valley. Today, some Kawaiisu people are enrolled in the Tule River Indian Tribe. Language The Kawaiisu language, or Tehachapi, is a member of the Southern Numic division of the Uto-Aztecan language family. The Kawaiisu homeland was bordered by speakers of non-Numic Uto-Aztecan languages. The Kitanemuk to the south spoke Takic, the Tübatulabal to the north spoke the Tübatulabal language, a linguistic isolate. The Yokuts (''Monilabal'') to the west were non-Uto-Azte ...

Potawatomi
The Potawatomi , also spelled Pottawatomi and Pottawatomie (among many variations), are a Native American people of the western Great Lakes region, upper Mississippi River and Great Plains. They traditionally speak the Potawatomi language, a member of the Algonquin family. The Potawatomi call themselves ''Neshnabé'', a cognate of the word ''Anishinaabe''. The Potawatomi are part of a long-term alliance, called the Council of Three Fires, with the Ojibway and Odawa (Ottawa). In the Council of Three Fires, the Potawatomi are considered the "youngest brother" and are referred to in this context as ''Bodwéwadmi'', a name that means "keepers of the fire" and refers to the council fire of three peoples. In the 18th century, they were pushed to the west by European/American encroachment and eventually removed from their lands in the Great Lakes region to reservations in Oklahoma. Under Indian Removal, they eventually ceded many of their lands, and most of the Potawatomi relocated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil Salinity
Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean. It can also come about through artificial processes such as irrigation and road salt. Natural occurrence Salts are a natural component in soils and water. The ions responsible for salination are: Na+, K+, Ca2+, Mg2+ and Cl−. Over long periods of time, as soil minerals weather and release salts, these salts are flushed or leached out of the soil by drainage water in areas with sufficient precipitation. In addition to mineral weathering, salts are also deposited via dust and precipitation. Salts may accumulate in dry regions, leading to naturally saline soils. This is the case, for example, in large parts of Australia. Human practices can increase the salinity of soils by the addition of salts in i ...

Stem Rust
Stem rust, also known as cereal rust, black rust, red rust or red dust, is caused by the fungus ''Puccinia graminis'', which causes significant disease in cereal crops. Crop species that are affected by the disease include bread wheat, durum wheat, barley and triticale. These diseases have affected cereal farming throughout history. The annual recurrence of stem rust of wheat in North Indian plains was discovered by Prof. K.C. Mehta. Since the 1950s, wheat strains bred to be resistant to stem rust have become available. Fungicides effective against stem rust are available as well. In 1999 a new virulent race of stem rust was identified against which most current wheat strains show no resistance. The race was named TTKSK (e.g. isolate Ug99). An epidemic of stem rust on wheat caused by race TTKSK spread across Africa, Asia and the Middle East, causing major concern due to the large numbers of people dependent on wheat for sustenance, thus threatening global food security.
