Johann Gottlieb Gleditsch
Johann Gottlieb Gleditsch (5 February 1714, in Leipzig – 5 October 1786, in Berlin) was a German physician and botanist known for pioneer investigations of plant sexuality and plant reproduction, reproduction. Biography He studied medicine and other subjects at the University of Leipzig (1728–35), where one of his instructors was the naturalist Johann Ernst Hebenstreit (1703–1757). From 1742, he gave lectures in physiology, botany and materia medica at the Viadrina European University, University of Frankfurt, afterwards relocating to Berlin as a professor of botany at the Charité, Collegium Medico-chirurgicum and director of the local Berlin-Dahlem Botanical Garden and Botanical Museum, botanical garden. Beginning in 1770, he gave lectures at the recently established institute of forestry, where he was instrumental in providing a scientific basis for the field of forestry. In his experiments involving plant movements, plant movement, he demonstrated the influence that cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilization, fertilized by Pollen, 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 formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and marchantiophyta, liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological Ecological niche, niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Clare Matterson CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discov ...

Acer × Zoeschense
''Acer'' × ''zoeschense'', the Zöschen maple, is a hybrid maple, a cross between ''Acer campestre'' (field maple), and either '' Acer lobelii'' (L'Obel's maple)Mitchell, A. F. (1974). ''A Field Guide to the Trees of Britain and Northern Europe''. Collins Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . or ''Acer cappadocicum'' (Cappadocian maple).Mitchell, A. F. (1982). ''The Trees of Britain and Northern Europe''. Collins van Gelderen, C.J. & van Gelderen, D.M. (1999). ''Maples for Gardens: A Color Encyclopedia''. While Field Maple parentage is universally accepted, the second parent is uncertain, though the tree's extensive production of root sprouts favours ''A. cappadocicum'' over ''A. lobelii''. It takes its name from Zöschen Nurseries in Germany, where it first appeared as a garden hybrid (as opposed to a hybrid occurring in nature) at some time before 1870. Description ''Acer'' × ''zoeschense'' is a medium-sized tree growing up to 20 m (66& ... [...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 varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate 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 hybridization, which include genetic and morph ...

Basal Shoot
Basal shoots, root sprouts, adventitious shoots, and suckers are words for various kinds of shoots that grow from adventitious buds on the base of a tree or shrub, or from adventitious buds on its roots. Shoots that grow from buds on the base of a tree or shrub are called basal shoots; these are distinguished from shoots that grow from adventitious buds on the roots of a tree or shrub, which may be called root sprouts or suckers. A plant that produces root sprouts or Stolon, runners is described as surculose. Water sprouts produced by adventitious buds may occur on the above-ground stem, branches or both of trees and shrubs. Suckers are shoots arising underground from the roots some distance from the base of a tree or shrub. __TOC__ In botany and ecology In botany, a root sprout or sucker is a severable plant that grows not from a seed but from the meristem of a root at the base of or a certain distance from the original tree or shrub. Root sprouts may emerge a substantial distan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#Asia and Europe, separated from Asia by the Drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus, Bosporus Strait.

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 all 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, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
