Hedera Pastuchovii
''Hedera pastuchovii'', (Araliaceae) is a species of ivy native to eastern Transcaucasia and listed in ''The Red Book of the Azerbaijan SSR, 1989''. It is an evergreen woody climber, growing in mixed forests to 20–30 m high where suitable trees are available but failing to thrive as a groundcover plant. It climbs by means of aerial rootlets which cling to the substrate. It is commonly known as Russian Ivy - so named from the formerly Russian-dominated area to which it is native. Description Leaves are thin, glossy, light green, entire or with wavy margins, 10–12 cm x 6–9 cm, often rounded and rarely oblong-elliptic, deeply or shallowly lobed, cordate or cuneate at the base. ''Hedera pastuchovii'' has a chromosome number of 2n= 144 (6x), making it a hexaploid. In a recent study of phylogenetics, ''H. pastuchovii,'' has been found to be related to other species of parsimony through a test of cpDNA restriction site variation analysis. In the clade containing Asia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Araliaceae
The Araliaceae are a family of flowering plants composed of about 43 genera and around 1500 species consisting of primarily woody plants and some herbaceous plants. The morphology of Araliaceae varies widely, but it is predominantly distinguishable based on its woody habit, tropical distribution, and the presence of simple umbels. There are numerous plants of economic importance. Some genera, such as ''Hedera'' (the ivies), ''Fatsia'' (Japanese aralias) and ''Schefflera'' (the umbrella trees)'', ''are used as ornamental foliage plants. The family also includes ''Panax ginseng'', the root of which is ginseng, used in traditional Chinese medicine. Overview The morphology of Araliaceae varies widely. Many studies have found that there is no unifying characteristic capable of classifying the family. In general, Araliaceae species have large, usually alternate leaves, often with aromatic ethereal oils, five-petaled flowers, two to five carpels, simple umbels, and berries without ca ...

Red Book Of Azerbaijan
The ''Red Book of Azerbaijan'' () is an official state document on the status of rare and endangered species of wild animals and plants in Azerbaijan. It contains information about the state, distribution and protection measures of animal and plant species within the Republic, including the section of the Caspian Sea belonging to Azerbaijan. Description According to the legislation, the ''Red Book'' is planned to be published every 10 years. The first edition was published in 1989. It listed 108 species of animals and 140 species of plants. Species are placed in one of 2 categories: endangered or rare. Endangered species are those that have sustained a substantial decrease in population and range and have reached a crisis level. Species with populations that are trending downward and are found in localized areas are considered rare. Animals and plants that are little studied, lack the necessary information about their number and resources in nature, and cause certain difficulties ...

Azerbaijan Soviet Socialist Republic
Azerbaijan ( az, Азәрбајҹан, Azərbaycan, italics=no), officially the Azerbaijan Soviet Socialist Republic (Azerbaijan SSR; az, Азәрбајҹан Совет Сосиалист Республикасы, Azərbaycan Sovet Sosialist Respublikası, italics=no, links=no; russian: Азербайджанская Советская Социалистическая Республика зССРAzerbaydzhanskaya Sovetskaya Sotsialisticheskaya Respublika zSSR}), also referred to as Soviet Azerbaijan, was one of the constituent republics of the Soviet Union between 1922 and 1991. Created on 28 April 1920 when the Russian Soviet Federative Socialist Republic brought pro-Soviet figures to power in the region, the first two years of the Azerbaijani SSR were as an independent country until incorporation into the Transcausasian SFSR, along with the Armenian SSR and the Georgian SSR. In December 1922, the Transcaucasian SFSR became part of the newly established Soviet Union. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) *Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives *Bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance :'' Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' (a sequoia) Leaf longevity in evergreen plants varies from a few months ...

CpDNA
Chloroplast DNA (cpDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast contains ribosomes and performs protein synthesis revealed that the chloroplast is genetically semi-autonomous. The first complete chloroplast genome sequences were published in 1986, ''Nicotiana tabacum'' (tobacco) by Sugiura and colleagues and ''Marchantia polymorpha'' (liverwort) by Ozeki et al. Since then, a great number of chloroplast DNAs from various species have been sequenced. Molecular structure Chloroplast DNAs are circular, and are typically 120,000–170,000 base pairs long. They can have a contour length of around 30–60 micrometers, and have a mass of about 80–1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alborz
The Alborz ( fa, البرز) range, also spelled as Alburz, Elburz or Elborz, is a mountain range in northern Iran that stretches from the border of Azerbaijan along the western and entire southern coast of the Caspian Sea and finally runs northeast and merges into the smaller Aladagh Mountains and borders in the northeast on the parallel mountain ridge Kopet Dag in the northern parts of Khorasan. All these mountains are part of the much larger Alpide belt. This mountain range is divided into the Western, Central, and Eastern Alborz Mountains. The Western Alborz Range (usually called the Talysh) runs south-southeastward almost along the western coast of the Caspian Sea. The Central Alborz (the Alborz Mountains in the strictest sense) runs from west to east along the entire southern coast of the Caspian Sea, while the Eastern Alborz Range runs in a northeasterly direction, toward the northern parts of the Khorasan region, southeast of the Caspian Sea.

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 ...
