Strawberries Time-lapse
The garden strawberry (or simply strawberry; ''Fragaria × ananassa'') is a widely grown Hybrid (biology), hybrid plant cultivated worldwide for its fruit. The genus ''Fragaria'', the strawberries, is in the rose family, Rosaceae. The fruit is appreciated for its aroma, bright red colour, juicy texture, and sweetness. It is eaten either fresh or in prepared foods such as fruit preserves, jam, ice cream, and chocolates. Artificial strawberry flavourings and aromas are widely used in commercial products. Botanically, the strawberry is not a berry (botany), berry, but an aggregate fruit, aggregate accessory fruit, accessory fruit. Each apparent 'seed' on the outside of the strawberry is actually an achene, a botanical fruit with a seed inside it. The garden strawberry was first bred in Brittany, France, in the 1750s via a cross of ''Virginia strawberry, F. virginiana'' from eastern North America and ''Fragaria chiloensis, F. chiloensis'', which was brought from Chile by Amédé ...

Antoine Nicolas Duchesne
Antoine Nicolas Duchesne (born 7 October 1747 Versailles (city), Versailles; died 18 February 1827 Paris) was a French botanist known for his keen observation of variation within species, and for demonstrating that species are not immutable, because mutations can occur.Darrow, G.M. 1966. The Strawberry: History, Breeding and Physiology. Holt, Rinehart and Winston. "As Duchesne's observations were unaided by knowledge of modern concepts of genetics and molecular biology, his insight was truly remarkable." His particular interests were in strawberries and gourds.Ratcliff, M. J. (2007). ''Duchesne’s Strawberries: Between Growers’ Practices and Academic Knowledge''. In S. Müller-Wille and H.-J.

Fragaria Vesca
''Fragaria vesca'', commonly called the wild strawberry, woodland strawberry, Alpine strawberry, Carpathian strawberry or European strawberry, is a Perennial plant, perennial herbaceous plant in the Rosaceae, rose family that grows naturally throughout much of the Northern Hemisphere, and that produces edible fruits. The Latin binomial nomenclature, specific epithet ''vesca'' literally means "thin" or "feeble", but likely carries the sense "edible" in this context (compare ''vescor'', "to eat"). 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. Its fruit persistence (botany), persists for an average of 1.2 days, which is possibly the shortest persistence of any fleshy fruit in Europe. It bears an average of ...

Chromosome
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. These eukaryotic chromosomes display a complex three-dimensional structure that has a significant role in transcriptional regulation. Normally, chromosomes are 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 stage occurs, each chromosome is duplicated ( S phase), and the two copies are joined by a centromere—resulting in either an X-shaped structure if the centromere is located equatorially, or a two-armed structure if the centromere is located distally; the jo ...

Octoploid
Polyploidy is a condition in which the cells of an organism have more than two paired sets of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one from each of two parents; each set contains the same number of chromosomes, and the chromosomes are joined in pairs of homologous chromosomes. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis; the sporophyte generation is diploid and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Clare Matterson CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discov ...

Isleworth
Isleworth ( ) is a suburban town in the London Borough of Hounslow, West London, England. It lies immediately east of Hounslow and west of the River Thames and its tributary the River Crane, London, River Crane. Isleworth's original area of settlement, alongside the Thames, is known as Old Isleworth. The northwest corner of the town, bordering on Osterley to the north and Lampton to the west, is known as Spring Grove. Isleworth's former River Thames, Thames frontage of approximately one mile, excluding that of the Syon Park estate, was reduced to little over half a mile in 1994 when a borough boundary realignment was effected in order to unite the district of St Margaret's wholly within London Borough of Richmond upon Thames. As a result, most of Isleworth's riverside is that part overlooking the islet of Isleworth Ait: the short-length River Crane flows into the Thames south of the Isleworth Ait, and its artificial distributary the Duke of Northumberland's River west of the ...

Palace Of Versailles
The Palace of Versailles ( ; ) is a former royal residence commissioned by King Louis XIV located in Versailles, Yvelines, Versailles, about west of Paris, in the Yvelines, Yvelines Department of Île-de-France, Île-de-France region in France. The palace is owned by the government of France and since 1995 has been managed, under the direction of the Ministry of Culture (France), French Ministry of Culture, by the Public Establishment of the Palace, Museum and National Estate of Versailles. About 15,000,000 people visit the palace, park, or gardens of Versailles every year, making it one of the most popular tourist attractions in the world. Louis XIII built a hunting lodge at Versailles in 1623. His successor, Louis XIV, expanded the château into a palace that went through several expansions in phases from 1661 to 1715. It was a favourite residence for both kings, and in 1682, Louis XIV moved the seat of his court and government to Versailles, making the palace the ''de fact ...

Chelsea, London
Chelsea is an area in West London, England, due south-west of Kilometre zero#Great Britain, Charing Cross by approximately . It lies on the north bank of the River Thames and for postal purposes is part of the SW postcode area, south-western postal area. Chelsea historically formed a manor and parish in the Ossulstone hundred of Middlesex, which became the Metropolitan Borough of Chelsea in 1900. It merged with the Metropolitan Borough of Kensington, forming the Royal Borough of Kensington and Chelsea upon the creation of Greater London in 1965. The exclusivity of Chelsea as a result of its high property prices historically resulted in the coining of the term "Sloane Ranger" in the 1970s to describe some of its residents, and some of those of nearby areas. Chelsea is home to one of the largest communities of Americans living outside the United States, with 6.53% of Chelsea residents having been born in the U.S. History Early history The word ''Chelsea'' (also formerly ' ...

Stolon
In biology, a stolon ( from Latin ''wikt:stolo, stolō'', genitive ''stolōnis'' – "branch"), also known as a runner, is a horizontal connection between parts of an organism. It may be part of the organism, or of its skeleton. Typically, animal stolons are exoskeletons (external skeletons). In botany In botany, stolons are plant stems which grow at the soil surface or just below ground that form adventitious roots at the Node (botany), nodes, and new plants from the buds. Stolons are often called runners. Rhizomes, in contrast, are root-like stems that may either grow horizontally at the soil surface or in other orientations underground. Thus, not all horizontal stems are called stolons. Plants with stolons are called stoloniferous. A stolon is a plant propagation strategy and the complex of individuals formed by a mother plant and all its Cloning, clones produced from stolons form a single genetic individual, a genet (biology), genet. Morphology Stolons may have long or shor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asexual Propagation
Plant propagation is the process by which new plants grow from various sources, including seeds, cuttings, and other plant parts. Plant propagation can refer to both man-made and natural processes. Propagation typically occurs as a step in the overall cycle of plant growth. For seeds, it happens after ripening and dispersal; for vegetative parts, it happens after detachment or pruning; for asexually-reproducing plants, such as strawberry, it happens as the new plant develops from existing parts. Countless plants are propagated each day in horticulture and agriculture. Plant propagation is vital to agriculture and horticulture, not just for human food production but also for forest and fibre crops, as well as traditional and herbal medicine. It is also important for plant breeding. Sexual propagation Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Garden Of Earthly Delights
''The Garden of Earthly Delights'' () is the modern title given to a triptych oil painting on oak panels painted by the Early Netherlandish master Hieronymus Bosch, between 1490 and 1510, when Bosch was between 40 and 60 years old. Bosch's religious beliefs are unknown, but interpretations of the work typically assume it is a warning against the perils of temptation. The outer panels place the work on the Third Day of Creation. The intricacy of its symbolism, particularly that of the central panel, has led to a wide range of scholarly interpretations over the centuries. Twentieth-century art historians are divided as to whether the triptych's central panel is a moral warning or a panorama of the paradise lost. He painted three large triptychs (the others are '' The Last Judgment'' of 1482 and '' The Haywain Triptych'' of 1516) that can be read from left to right and in which each panel was essential to the meaning of the whole. Each of these three works presents disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
