Mountain Papaya
The mountain papaya (''Vasconcellea pubescens'') also known as mountain pawpaw, papayuelo, chamburo, or simply "papaya" is a species of the genus ''Vasconcellea'', native to the Andes of northwestern South America from Colombia south to central Chile, typically growing at altitudes of . It has also been known as ''Carica pubescens.'' Description ''Vasconcellea pubescens'' is an evergreen pachycaul shrub or small tree with an average height of ca. and can grow up to tall. It has one central stem and palmate leaves of 5-7 lobes with thick pubescence on the underside of the leaf and petiole. The petioles are long and the top of the leaf has no pubescence. It has a fast growth rate which is one of the reasons it is considered invasive in some regions (see section Invasiveness) and it has an ecological preference for higher altitudes. This plant is mostly dioecious but can be found to be monoecious or even andromonoecious. The existence of flowers of different sexes appears to ...

Peter Joseph Lenné
Peter Joseph Lenné (the Younger) (29 September 1789 – 23 January 1866) was a Prussian gardener and landscape architect. As director general of the Royal Prussian palaces and parks in Potsdam and Berlin, his work shaped the development of 19th-century German garden design in the Neoclassical style. Laid out according to the principles of the English landscape garden, his parks are now World Heritage Sites. Life and works Lenné was born in Bonn, then part of the Electorate of Cologne, the son of the court and university gardener Peter Joseph Lenné the Elder (1756–1821), and his wife, Anna Catharina Potgieter (also Potgeter), daughter of the mayor of Rheinberg. The Lenné family descended from the Prince-Bishopric of Liège. Circa 1665, Peter Joseph's ancestor Augustin Le Neu had settled in Poppelsdorf near Bonn as court gardener of Archbishop-Elector Maximilian Henry of Bavaria. Childhood and development Having obtained his ''Abitur'' degree, Peter Joseph Lenné decided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papaya
The papaya (, ), papaw, () or pawpaw () is the plant species ''Carica papaya'', one of the 21 accepted species in the genus ''Carica'' of the family Caricaceae. It was first domesticated in Mesoamerica, within modern-day southern Mexico and Central America. In 2020, India produced 43% of the world supply of papayas. Etymology The word ''papaya'' comes from Arawak via Spanish, this is also where ''papaw'' and ''pawpaw'' come from. Description The papaya is a small, sparsely branched tree, usually with a single stem growing from tall, with spirally arranged leaves confined to the top of the trunk. The lower trunk is conspicuously scarred where leaves and fruit were borne. The leaves are large, in diameter, deeply palmately lobed, with seven lobes. All parts of the plant contain latex in articulated laticifers. Flowers Papayas are dioecious. The flowers are five-parted and highly dimorphic; the male flowers have the stamens fused to the petals. The female flowers h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crops Originating From Colombia
A crop is a plant that can be grown and harvested extensively for profit or subsistence agriculture, subsistence. When the plants of the same kind are cultivated at one place on a large scale, it is called a crop. Most crops are cultivated in agriculture or hydroponics. Crops may include macroscopic fungus (e.g. mushrooms) and marine seaweed, macroalga (e.g. seaweed farming, seaweed), some of which are grown in aquaculture. Most crops are harvested as food for humans or fodder for livestock. Some crops are gathered from the wild often in a form of intensive gathering (e.g. ginseng, yohimbe, and eucommia). Important non-food crops include horticulture, floriculture and industrial crops. Horticulture crops include plants used for other crops (e.g. fruit trees). Floriculture crops include bedding plants, houseplants, flowering garden and pot plants, cut cultivated greens, and cut flowers. Industrial crops are produced for clothing (fiber crops e.g. cotton), biofuel (energy crops, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Introgression
Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may take many hybrid generations before significant backcrossing occurs. This process is distinct from most forms of gene flow in that it occurs between two populations of different species, rather than two populations of the same species. Introgression also differs from simple hybridization. Simple hybridization results in a relatively even mixture; gene and allele frequencies in the first generation will be a uniform mix of two parental species, such as that observed in mules. Introgression, on the other hand, results in a complex, highly variable mixture of genes, and may only involve a minimal percentage of the donor genome.

F1 Hybrid
An F1 hybrid (also known as filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. F1 hybrids are used in genetics, and in selective breeding, where the term F1 crossbreed may be used. The term is sometimes written with a subscript, as F hybrid. Subsequent generations are called F, F, etc. The offspring of distinctly different parental types produce a new, uniform phenotype with a combination of characteristics from the parents. In fish breeding, those parents frequently are two closely related fish species, while in plant and animal breeding, the parents often are two inbred lines. Gregor Mendel focused on patterns of inheritance and the genetic basis for variation. In his cross-pollination experiments involving two true-breeding, or homozygous, parents, Mendel found that the resulting F1 generation was heterozygous and consistent. The offspring showed a combination of the phenotypes from each parent that were genetically dominant. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papaya Ringspot Virus
''Papaya ringspot virus'' (PRSV) is a pathogenic plant virus in the genus ''Potyvirus'' and the virus family ''Potyviridae'' which primarily infects the papaya tree. The virus is a non-enveloped, flexuous rod-shaped particle that is between 760–800 nm long and 12 nm in diameter. It is transmitted between plants by mechanical activities like pruning and by numerous aphid species such as ''Myzus persicae''. No seed transmission has been detected. There are two major types of this virus that are serologically indistinguishable and are so closely genetically related that they are now considered the same virus species. The type that gave the virus its name are the Type P isolates (PRSV-P). This type infects papaya and several members of the melon family (Cucurbitaceae). The other type, Type W isolates (PRSV-W), does not infect papaya. Isolates of PRSV-W do infect cucurbits such as watermelon, cucumber, and squash and were originally known as ''Watermelon mosaic vi ...

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...
