Pinus × Rhaetica
''Pinus'' × ''rhaetica'', commonly known as Rhætic pine, the species name refers to the Rhætica alps, located in eastern Switzerland and western Austria. Rhaetic pine is described as a natural hybrid of Mountain pine ('' Pinus mugo'') and Scots pine ('' Pinus sylvestris''). It is a coniferous tree nothospecies located in the subsection ''Pinus''. Description ''Pinus'' × ''rhaetica'' has variable morphology. Commonly Rhætic pines grow as trees, although some are shrubby in form. The trees are 4.5–8 m tall, 3 m broad. The trunk is gray-brown, grayer and more frequently divided into irregular plates than in ''Pinus mugo''. The bark on major branches resembles that of ''P. sylvestris'' in being reddish brown with papery flakes, but it can also be more like ''P. mugo'' and greyish and persistent. The leaves (needles) are 4 cm long, usually fresh or dark green like those of ''P. mugo'', although they can be bluish green like those of ''P. sylvestris'', depending on whe ...

Trentino
Trentino ( lld, Trentin), officially the Autonomous Province of Trento, is an autonomous province of Italy, in the country's far north. The Trentino and South Tyrol constitute the region of Trentino-Alto Adige/Südtirol, an autonomous region under the constitution. The province is composed of 166 ''comuni'' (municipalities). Its capital is the city of Trento (Trent). The province covers an area of more than , with a total population of 541,098 in 2019.

Bark (botany)
Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost layer of the periderm. The outer bark on older stems includes the dead tissue on the surface of the stems, along with parts of the outermost periderm and all the tissues on the outer side of the periderm. The outer bark on trees which lies external to the living periderm is also called the rhytidome. Products derived from bark include bark shingle siding and wall coverings, spices and other flavorings, tanbark for tannin, resin, latex, medicines, poisons, various hallucinogenic chemicals and cork. Bark has been used to make cloth, canoes, and ropes and used as a surface for paintings and map making. A number of plants a ...

Pinus
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Hybridization In Pines
Both naturally and artificially occurring pine species ''Pine, (Pinus)'' can Hybrid (biology), hybridize, combining their genetic material and sometimes creating hybrids that can be more or less Heterosis, vigorous than their parent species. An example of a naturally occurring hybrid pine is ''Pinus × sondereggeri,'' a naturally occurring cross between loblolly pine (''P. taeda'') and longleaf pine (''P. palustris''). An example of the many artificial hybrids is ''Pinus lambertiana'' × ''Pinus armandii, P. armandii.'' Subgenus ''Pinus'' Includes both natural and artificial pine hybrids.

Baltic States
The Baltic states, et, Balti riigid or the Baltic countries is a geopolitical term, which currently is used to group three countries: Estonia, Latvia, and Lithuania. All three countries are members of NATO, the European Union, the Eurozone, and the OECD. The three sovereign states on the eastern coast of the Baltic Sea are sometimes referred to as the "Baltic nations", less often and in historical circumstances also as the "Baltic republics", the "Baltic lands", or simply the Baltics. All three Baltic countries are classified as high-income economies by the World Bank and maintain a very high Human Development Index. The three governments engage in intergovernmental and parliamentary cooperation. There is also frequent cooperation in foreign and security policy, defence, energy, and transportation. The term "Baltic states" ("countries", "nations", or similar) cannot be used unambiguously in the context of cultural areas, national identity, or language. While the majority ...

Montane Ecosystems
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conifer Cone
A conifer cone (in formal botany, botanical usage: strobilus, plural strobili) is a seed-bearing organ on gymnosperm plants. It is usually woody, ovoid to globular, including scales and bracts arranged around a central axis, especially in conifers and cycads. The cone of Pinophyta (conifer clade) contains the plant sexuality, reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually herbaceous plant, herbaceous and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the cone (geometry), geometric cone. The individual plates of a cone are known as ''scales''. The ''umbo'' of a conifer cone refers to the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale. The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
