Parrot Tulip
Parrot tulips are a tulip cultivar group known for their bright colors and petals. The petals have a "serrated" or "fringed" look. The flowers bloom in late spring and reach a size of almost in length. Although they are perennials by nature٫ they are often grown as annuals. Parrot tulips come in a wide variety of colors, usually being brightly colored, but can come in darker colors. The flowers originated in France and were brought to the Netherlands in the 18th century. The flower buds are green in color, but as the flowers mature, their bright colors start to appear. Parrot tulips not a species but are a group of cultivars with the name ''Tulipa'' Parrot Group. Parrot tulips are the result of natural mutations to single late tulips and triumph tulips. During the 17th and 18th century the most notable mutations were to color patterns with growers attempting to influence the color of the tulips using pigeon droppings, old plaster and even dirty waste water from the kitchen.

Tulip
Tulips are spring-blooming perennial herbaceous bulbiferous geophytes in the ''Tulipa'' genus. Their flowers are usually large, showy, and brightly coloured, generally red, orange, pink, yellow, or white. They often have a different coloured blotch at the base of the tepals, internally. Because of a degree of variability within the populations and a long history of cultivation, classification has been complex and controversial. The tulip is a member of the lily family, Liliaceae, along with 14 other genera, where it is most closely related to '' Amana'', ''Erythronium'', and '' Gagea'' in the tribe Lilieae. There are about 75 species, and these are divided among four subgenera. The name "tulip" is thought to be derived from a Persian word for turban, which it may have been thought to resemble by those who discovered it. Tulips were originally found in a band stretching from Southern Europe to Central Asia, but since the seventeenth century have become widely naturalise ...

Classification Of Plants
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, "plant systematics" involves relationships between plants and their evolution, especially at the higher levels, whereas "plant taxonomy" deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed. Plant taxonomy is well known for being turbulent, and traditionally not having any close agreement on circumscription and placement of taxa. See the list of systems of plant taxonomy. Background Classification systems serve the purpose of grouping organisms by characteristics common to each group. Plants are distinguished from animals by various trai ...

Johann Jakob Walther (artist)
Johann Jakob Walther (23 January 1604 – 1676/7 Strasbourg) was a painter and natural history illustrator, who chronicled the life of Strasbourg during the Thirty Years' War, but is best known for his work ''Horti Itzeinensis'' aka the ''Nassau Florilegium'' depicting flowering plants from the gardens of Johann, Count of Nassau-Idstein at Idstein. Walther was the son of Gerard Walther. He probably trained in the workshop of miniaturist Friedrich Brentel. He left Strasbourg around 1618 and returned in 1635. He was elected to the Grand Council of the city in 1659. His meeting in Strasbourg with the Count was a decisive moment in his career, since the Count became one of his most important patrons. This was an era when the purpose of a florilegium was to serve as a pictorial catalogue of a garden, and correspondence shows that the Count invited Walther to Idstein near Frankfurt to spend the spring and summer months there to paint flowers and fruits from the garden - Walther di ...

Magenta
Magenta () is a purple-red color. On color wheels of the RGB color model, RGB (additive) and subtractive color, CMY (subtractive) color models, it is located precisely midway between blue and red. It is one of the four colors of ink used in color printing by most Color printing, color printers, along with yellow, cyan, and black to make all the other colors. Magenta is a color made by mixing red and blue. The tone of magenta used in printing, Shades of magenta, printer's magenta, is redder than the magenta of the RGB (additive) model, the former being closer to Rose (color), rose. Magenta took its name from an aniline dye made and patented in 1859 by the French chemist François-Emmanuel Verguin, who originally called it ''fuchsine''. It was renamed to celebrate the French-Sardinian victory under French Emperor Napoleon III at the Battle of Magenta against the larger army of the Austrian Empire on 4 June 1859 near the Italian town of Magenta, Lombardy, Magenta, at the time in Au ...

Blue-green
Blue-green is the color between blue and green. It belongs to the shades of cyan, cyan family. Variations Cyan Cyan is the blue-green color that is between blue and green on a modern RGB color model, RGB color wheel. The modern RGB color wheel replaced the traditional old-fashioned RYB color wheel because it is possible to display much brighter and more saturated colors using the primary and secondary colors of the RGB color wheel. In the terminology of color theory, RGB color space has a much larger color gamut than RYB color space. The first recorded use of ''cyan'' as a color name in English language, English was in 1879. Turquoise The color turquoise is that of the semi-precious stone turquoise, which is a light tone of blue-green. Its first recorded use as a color name in English language, English is from 1573. Green-blue Green-blue is a Crayola crayon color from 1958 to 1990. Bondi blue Bondi blue belongs to the cyan family of blues. It is very si ...

Parrot
Parrots (Psittaciformes), also known as psittacines (), are birds with a strong curved beak, upright stance, and clawed feet. They are classified in four families that contain roughly 410 species in 101 genus (biology), genera, found mostly in tropics, tropical and subtropics, subtropical regions. The four families are the Psittaculidae (Old World parrots), Psittacidae (African and New World parrots), Cacatuidae (cockatoos), and Strigopidae (New Zealand parrots). One-third of all parrot species are threatened by extinction, with a higher aggregate extinction risk (Red List Index, IUCN Red List Index) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperateness, temperate regions as well. The greatest biodiversity, diversity of parrots is in South America and Australasia.

Tulip Breaking Virus
Tulip breaking virus is one of five plant viruses of the family ''Potyviridae'' that cause color-breaking of tulip flowers. These viruses infect plants in only two genera of the family Liliaceae: tulips (''Tulipa'') and lilies (''Lilium''). Also known as the tulip break virus, lily streak virus, lily mosaic virus, or simply TBV, tulip breaking virus is most famous for its dramatic effects on the color of the tulip perianth, an effect highly sought after during the 17th-century Dutch "tulip mania". Tulip breaking virus is a potyvirus. A distant serological relationship between Tulip breaking virus and tobacco etch virus was discovered in 1971. Tulip breaking virus (TBV), tulip top-breaking virus (TTBV), tulip bandbreaking virus (TBBV), Rembrandt tulip-breaking virus (ReTBV), and lily mottle virus (LMoV) have all been identified as potyviruses by serology and potyvirus-specific polymerase chain reaction (PCR). In addition, sequence analysis of amplified DNA fragments has classi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication ( translesion synthesis). Mutations may also result from substitution, insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics ( phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutati ...
