Strawberries
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 s ...

Antoine Nicolas Duchesne
Antoine Nicolas Duchesne (born 7 October 1747 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.

Ovary (botany)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through double fertilization of unprotected ovules, they produce naked seeds that do not ...

Photoperiod
Photoperiodism is the physiological reaction of organisms to the length of night or a dark period. It occurs in plants and animals. Plant photoperiodism can also be defined as the developmental responses of plants to the relative lengths of light and dark periods. They are classified under three groups according to the photoperiods: short-day plants, long-day plants, and day-neutral plants. Plants Many flowering plants (angiosperms) use a photoreceptor protein, such as phytochrome or cryptochrome, to sense seasonal changes in night length, or photoperiod, which they take as signals to flower. In a further subdivision, ''obligate'' photoperiodic plants absolutely require a long or short enough night before flowering, whereas ''facultative'' photoperiodic plants are more likely to flower under one condition. Phytochrome comes in two forms: Pr and Pfr. Red light (which is present during the day) converts phytochrome to its active form (pfr). This then triggers the plant to grow. ...

Секрет пыльцы
Secret (russian: Секрет, lit.: ''Secret'') was a Soviet Russian rock and roll band founded in 1982 in Leningrad. The band's musical style and image were inspired from 1950s and 1960s western music, in particular by The Beatles. The band's name was inspired by the Beatles song ' Do You Want to Know a Secret?'. Secret called themselves a "Beat Quartet" and were, along with Bravo, a part of Soviet rock and roll revival of 1980s. The original lineup lasted until 1990, when frontman Maxim Leonidov emigrated to Israel. The band continued with different lineups without great success. Since 1997 the original lineup has occasionally performed together including for anniversary shows in 2003 and 2007. Many Secret hits of the 1980s still receive a lot of airplay on Russian FM stations. at the moskva.fm Original members *[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breeding Of Strawberries
The breeding of strawberries started with the selection and cultivation of European strawberry species in western Europe in the 15th century while a similar discovery and cultivation occurred in Chile. The most commonly consumed strawberry species in modern times is the garden strawberry, a species derived from hybridization of two other species, with the scientific name ''Fragaria'' × ''ananassa'', but there are many species of strawberries, several others of which are cultivated to some extent. The strawberry species fall into several different genetic types, based on their number of chromosomes. Strawberry growers have employed many breeding techniques, starting with traditional plant breeding and then moving on to molecular breeding and genetic engineering in the 20th century. The history of the breeding of strawberries Early breeding European breeding before American contact In Europe, there were three main strawberry species. They are ''Fragaria vesca'', ''F. viridis'' an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
