Fragaria Viridis
''Fragaria viridis'', commonly called creamy strawberry or green strawberry is a species of strawberry native to Europe and central Asia. It has fruits with fine flavour. They have surprisingly little of the usual strawberry aroma, but a refreshing acidity, and sometimes ripen without becoming red. When they are plucked from the plant, the calyx will usually adhere and they will detach with a noticeable snapping sound.Den Virtuella Floran Swedish site with good ''F. viridis'' photos.

Richard Weston (botanist)
Richard Weston (1733 – 20 October 1806) was an English botanist. Life and work Weston was originally a thread-hosier of Leicester, but in some of his anonymous works describes himself as "a country gentleman". In 1773, he was living at Kensington Gore, but later was living at Leicester where he was secretary of the local agricultural society. From the number of his published works, it is evident he had a very wide knowledge of plants and plant literature. His first major work ''"Tracts on Practical Agriculture and Gardening"'', which contained a catalogue of English writers on husbandry gardening and botany, was published in 1769 and dedicated to the Society of Arts. He wrote two multi-part works with Latin names, the Botanicu Universalis and the Flora Anglicana and a number of smaller works, as well as articles in the Gentleman's Magazine ''The Gentleman's Magazine'' was a monthly magazine founded in London, England, by Edward Cave in January 1731. It ran uninterrupted f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Calyx (botany)
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Haploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.

Chromosomes
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated (S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called sis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fragaria Vesca
''Fragaria vesca'', commonly called the wild strawberry, woodland strawberry, Alpine strawberry, Carpathian strawberry or European strawberry, is a perennial herbaceous plant in the rose family that grows naturally throughout much of the Northern Hemisphere, and that produces edible fruits. The Latin specific epithet ''vesca'' means "thin, feeble". Description Five to eleven soft, hairy white flowers are borne on a green, soft fresh-hairy stalk that usually lifts them above the leaves. The light-green leaves are trifoliate (in threes) with toothed margins. The plant spreads mostly by means of runners ( stolons), but the seeds are viable and establish new populations. Taxonomy Vilmorin-Andrieux (1885) makes a distinction between wild or wood strawberries (''Fragaria vesca'') and alpine strawberries (''Fragaria alpina''), a distinction which is not made by most seed companies or nurseries, which usually sell ''Fragaria vesca'' as "alpine strawberry".

Musk Strawberry
The musk strawberry or hautbois strawberry (''Fragaria moschata''), is a species of strawberry native to Europe. Its French name ''hautbois'' strawberry may be anglicised as hautboy strawberry. The plants are hardy and can survive in many weather conditions. They are cultivated commercially on a small scale, particularly in Italy. The fruit are small and round; they are used in the gourmet community for their intense aroma and flavour, which has been compared to a mixture of regular strawberry, raspberry and pineapple. Popular cultivated varieties include 'Capron' and 'Profumata di Tortona'. Distribution Musk strawberries grow wild to a limited extent in the forests of Central Europe, north into Scandinavia, and east into Russia. The musk strawberry is found growing along the edges of forests and requires moist and sheltered sites since they do not tolerate temperature fluctuations. Polyploidy All strawberries have a base haploid count of 7 chromosomes. ''Fragaria moschata'' is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strawberry
The garden strawberry (or simply strawberry; ''Fragaria × ananassa'') is a widely grown hybrid species of the genus '' Fragaria'', collectively known as the strawberries, which are cultivated worldwide for their fruit. The fruit is widely appreciated for its characteristic aroma, bright red color, juicy texture, and sweetness. It is consumed in large quantities, either fresh or in such prepared foods as jam, juice, pies, ice cream, milkshakes, and chocolates. Artificial strawberry flavorings and aromas are also widely used in products such as candy, soap, lip gloss, perfume, and many others. The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of ''Fragaria virginiana'' from eastern North America and ''Fragaria chiloensis'', which was brought from Chile by Amédée-François Frézier in 1714. Cultivars of ''Fragaria'' × ''ananassa'' have replaced, in commercial production, the woodland strawberry ('' Fragaria vesca''), which was the first straw ...
