Fragaria Cascadensis
''Fragaria cascadensis'' is a species of strawberry found in the Cascades Mountains described in 2012. The vernacular name Cascade strawberry was suggested by the describing author. Taxonomy ''F. cascadensis'' was first described in 2012 by Kim E. Hummer of the USDA ARS National Clonal Germplasm Repository in Corvallis, Oregon. The holotype plant was collected from a disturbed area along a road in Lane County Oregon. The holotype plant was in a south facing area growing in association with ''Pseudotsuga menziesii''. The species was named ''Fragaria cascadensis'' in allusion to the Oregon Cascade Mountains. Description It is a perennial, with the typical white flowers of its genus. It differs from other strawberry species by having hairs on the upper side of its leaves, as opposed to the underside or not present at all and a different middle leaflet. It begins growing after snow melt ( May or early June in that region), flowers are born around early July and fruit ripens d ...

Fragaria
''Fragaria'' () is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. There are more than 20 described species and many hybrids and cultivars. The most common strawberries grown commercially are cultivars of the garden strawberry, a hybrid known as ''Fragaria'' × ''ananassa''. Strawberries have a taste that varies by cultivar, and ranges from quite sweet to rather tart. Strawberries are an important commercial fruit crop, widely grown in all temperate regions of the world. Description Strawberries are not berries in the botanical sense.Esau, K. 1977. ''Anatomy of seed plants''. John Wiley and Sons, New York. The fleshy and edible part of the "fruit" is a receptacle, and the parts that are sometimes mistakenly called "seeds" are achenes and therefore the true botanical fruits. Etymology The genus name derives from ("strawberry") and , a suffix used to create feminine nouns and plant names. The Latin name is tho ...

Cascades Mountains
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at . part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and a major e ...

Pseudotsuga Menziesii
The Douglas fir (''Pseudotsuga menziesii'') is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir (''P. menziesii'' var. ''menziesii''), Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and Mexican Douglas-fir (''P. menziesii'' var. ''lindleyana''). Despite its common names, it is not a true fir (genus ''Abies''), spruce (genus ''Picea''), or pine (genus ''Pinus''). It is also not a hemlock; the genus name ''Pseudotsuga'' means "false hemlock". Description Douglas-firs are medium-size to extremely large evergreen trees, tall (although only ''Pseudotsuga menziesii var. menziesii'', common name coast Douglas-firs, reach heights near 100 m) and commonly reach in diameter, although trees with diameters of almost exist.

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Columbia River
The Columbia River (Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific. The Columbia has the 36th greatest discharge of any river in the world. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years.

Crater Lake
Crater Lake (Klamath language, Klamath: ''Giiwas'') is a volcanic crater lake in south-central Oregon in the western United States. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a caldera that was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of , the lake is the List of lakes by depth, deepest in the United States. In the world, it ranks ninth for maximum depth, and third for mean (average) depth. Crater Lake features two small islands. Wizard Island, located near the western shore of the lake, is a cinder cone approximately 316 acres (128 ha) in size. Phantom Ship (island), Phantom Ship, a natural rock pillar, is located near the southern shore. Since 2002, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fragaria Iturupensis
''Fragaria iturupensis'', the Iturup strawberry, is a species of wild strawberry, endemic to Iturup in the Kuril Islands. It is noted to have relatively large berries for a wild species, similar in appearance to those of ''Fragaria virginiana''. Polyploidy All strawberries have a base haploid count of 7 chromosomes. ''Fragaria iturupensis'' was initially reported as octoploid Polyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes.

Fragaria × Vescana
''Fragaria'' × ''vescana'' is a hybrid strawberry cultivar that was created in an effort to combine the best traits of the garden strawberry (''Fragaria'' × ''ananassa''), which has large berries and vigorous plants, with the woodland strawberry (''Fragaria vesca''), which has an exquisite flavour, but small berries. This cross cannot take place naturally. ''Fragaria'' × ''ananassa'' has eight sets of chromosomes whereas ''Fragaria vesca'' has only two sets. Repeated attempts to cross these resulted in sterile offspring. Researchers treated tissue from a ''Fragaria vesca'' plant with colchicine to create a mutant plant with four sets of chromosomes. This mutant was then crossed with a ''Fragaria'' × ''ananassa'' plant, and vigorous fertile offspring were obtained. The offspring were found to be decaploid Polyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes.

Fragaria × Comarum Hybrids
There are several commercially important hybrids between '' Fragaria'' and ''Comarum'' species in existence. A name for ''Fragaria'' × ''Comarum'' is available as × ''Comagaria'' Büscher & G.H. Loos in Veroff. ohumer Bot. Ver. 2(1): 6. 2010 along with the combination × ''Comagaria rosea'' (Mabb.) Büscher & G.H. Loos. The first-generation hybrids have been recorded as heptaploid, i.e. with seven sets of chromosomes; four sets of chromosomes came from their octoploid strawberry parent, and three from their hexaploid ''Comarum'' parent.

Fragaria × Bringhurstii
''Fragaria'' × ''bringhurstii'' is a naturally occurring hybrid species of wild strawberry native to the West Coast of the United States. The species results from the natural intercrossing of ''Fragaria vesca'' and '' Fragaria chiloensis'', native species whose ranges overlap in that region. All strawberries have a base haploid count of 7 chromosomes. ''Fragaria'' × ''bringhurstii'' is pentaploid Polyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes. Most species whose cells have nuclei ( eukaryotes) are diploid, meaning they have two sets of chromosomes, where each set contain ..., having 5 pairs of these chromosomes for a total of 35 chromosomes, 7 from the ''F. vesca'' parent, and 28 from the ''F. chiloensis'' parent. Because of this odd number of chromosomes, this species possesses only limited fertility, due to problems of chromosome pairing during meiosis.
