Jakob Friedrich Ehrhart
Jakob Friedrich Ehrhart (4 November 1742, Holderbank, Aargau – 26 June 1795) was a German botanist, a pupil of Carl Linnaeus at Uppsala University, and later director of the Botanical Garden of Hannover, where he produced several major botanical works between 1780 and 1793. Ehrhart was the first author to use the rank of subspecies in botanical literature, and he published many subspecific names between 1780 and 1789. In 1779, Carl Peter Thunberg (1743–1828) named a genus of grasses, ''Ehrharta'', in Ehrhart's honor.

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Tree
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pasture
Pasture (from the Latin ''pastus'', past participle of ''pascere'', "to feed") is land used for grazing. Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing. Pasture lands in the narrow sense are distinguished from rangelands by being managed through more intensive agricultural practices of seeding, irrigation, and the use of fertilizers, while rangelands grow primarily native vegetation, managed with extensive practic ...

Nordic Countries
The Nordic countries (also known as the Nordics or ''Norden''; lit. 'the North') are a geographical and cultural region in Northern Europe and the North Atlantic. It includes the sovereign states of Denmark, Finland, Iceland, Norway and Sweden; the autonomous territories of the Faroe Islands and Greenland; and the autonomous region of Åland. The Nordic countries have much in common in their way of life, History of Scandinavia, history, religion and Nordic model, social structure. They have a long history of political unions and other close relations but do not form a singular entity today. The Scandinavism, Scandinavist movement sought to unite Denmark, Norway and Sweden into one country in the 19th century. With the dissolution of the union between Norway and Sweden (Norwegian independence), the independence of Finland in the early 20th century and the 1944 Icelandic constitutional referendum, this movement expanded into the modern organised Nordic cooperation. Since 196 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apomixis
In botany, apomixis is asexual reproduction without fertilization. Its etymology is Greek for "away from" + "mixing". This definition notably does not mention meiosis. Thus "normal asexual reproduction" of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis, but replacement of the seed by a plantlet or replacement of the flower by bulbils were categorized as types of apomixis. Apomictically produced offspring are genetically identical to the parent plant. Some authors included all forms of asexual reproduction within apomixis, but that generalization of the term has since died out. In flowering plants, the term "apomixis" is commonly used in a restricted sense to mean agamospermy, i.e., clonal reproduction through seeds. Although agamospermy could theoretically occur in gymnosperms, it appears to be absent in that group. Apogamy is a related term that has had various meanings over time. In plants with independent gametophytes (nota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in floweri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hedlundia Hybrida
''Hedlundia hybrida'' (formerly ''Sorbus hybrida''), the Swedish service-tree Finnish whitebeam, or oakleaf mountain ash, is a species of whitebeam native to Norway, eastern Sweden, south-western Finland, and locally in Latvia.Rushforth, K.

Aria Edulis
''Aria edulis'', the whitebeam or common whitebeam, is a species of deciduous tree in the family ''Rosaceae''. It is native to most of Europe as well as North Africa (Algeria, Morocco, Tunisia) and temperate Asia (Eastern Anatolia Region, Eastern Turkey, Armenia, Georgia). Typically compact and domed, with few upswept branches and almost-white underside of the leaves, it generally favours dry limestone and chalk soils. The plant sexuality, hermaphrodite cream-white flowers appear in May, are insect pollinated, and go on to produce scarlet berries, which are often eaten by birds. The cultivars ''A. edulis'' 'Lutescens', with very whitish-green early leaves, and ''A. edulis'' 'Majestica', with large leaves, have both gained the Royal Horticultural Society's Award of Garden Merit. The berries are edible when overripe (Bletting, bletted). It has a high capacity to form new shoots around the trunk. File:Weilburg - Tiergarten - Mehlbeere.jpg, Tree References Sorbus, aria ...

Torminalis Glaberrima
''Torminalis'' is a plant genus that has sometimes been included within the genus ''Sorbus'', as Section ''Torminaria''. It includes at least one species, ''Torminalis clusii'' (Schönb.-Tem.) K.R.Robertson & J.B.Phipps (=''Sorbus torminalis''). The species originally described as ''Sorbus orientalis'' is either considered to be a synonym of ''T. clusii'', or to be a second species, ''Torminalis orientalis'' (Schönb.-Tem.) K.R.Robertson & J.B.Phipps. Taxonomy It has recently become clear that the simple-leafed species traditionally included in ''Sorbus'' form a monophyletic group A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, ..., and the species of ''Torminalis'' could be included in a clade called ''Aria'' (=genus ''Aria'' or ''Sorbus'' subgenus ''Aria''). References T ...

Sorbus Aucuparia
''Sorbus aucuparia'', commonly called rowan (UK: /ˈrəʊən/, US: /ˈroʊən/) and mountain-ash, is a species of deciduous tree or shrub in the rose family. It is a highly variable species, and botanists have used different Circumscription (taxonomy), definitions of the species to include or exclude trees native to certain areas; a recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from Madeira, the British Isles and Iceland to Russia and northern China. Unlike many plants with similar distributions, it is not native to Japan. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It blossoms from May to June in dense corymbs of small yellowish white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species.

Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general meaning t ...
