Forcing (horticulture)
Forcing is the horticultural practice of bringing a cultivated plant into active growth outside of its natural growing season. Plants do not produce new growth or flowers (and hence fruit) during the winter, and many species only produce flowers or fruit for a very limited period. Forcing allows horticulturalists to produce these flowers and fruits at other times. This can be accomplished by cultural, physical, or chemical means, and is typically done to produce out-of-season flowers or fruit for display, consumption or sale. Forcing allows the more predictable production of products for sale, and can improve the quality of the products in some cases. Plants respond to different types of cues to break dormancy. Forcing usually involves manipulating the temperature of the plants. Forcing a certain plant may mean it needs a certain amount of time experiencing very cold weather, or experiencing hot weather prior to cold weather. They may also need to have a wet period or a dry period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horticulture
Horticulture is the branch of agriculture that deals with the art, science, technology, and business of plant cultivation. It includes the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. It also includes plant conservation, landscape restoration, landscape and garden design, construction, and maintenance, and arboriculture, ornamental trees and lawns. The study and practice of horticulture have been traced back thousands of years. Horticulture contributed to the transition from nomadic human communities to sedentary, or semi-sedentary, horticultural communities.von Hagen, V.W. (1957) The Ancient Sun Kingdoms Of The Americas. Ohio: The World Publishing Company Horticulture is divided into several categories which focus on the cultivation and processing of different types of plants and food items for specific purposes. In order to conserve the science of horticultur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Yorkshire
West Yorkshire is a metropolitan and ceremonial county in the Yorkshire and Humber Region of England. It is an inland and upland county having eastward-draining valleys while taking in the moors of the Pennines. West Yorkshire came into existence as a metropolitan county in 1974 after the reorganisation of the Local Government Act 1972 which saw it formed from a large part of the West Riding of Yorkshire. The county had a recorded population of 2.3 million in the 2011 Census making it the fourth-largest by population in England. The largest towns are Huddersfield, Castleford, Batley, Bingley, Pontefract, Halifax, Brighouse, Keighley, Pudsey, Morley and Dewsbury. The three cities of West Yorkshire are Bradford, Leeds and Wakefield. West Yorkshire consists of five metropolitan boroughs (City of Bradford, Calderdale, Kirklees, City of Leeds and City of Wakefield); it is bordered by the counties of Derbyshire to the south, Greater Manchester to the south-west, Lancash ...

Vernalization
Vernalization (from Latin ''vernus'', "of the spring") is the induction of a plant's flowering process by exposure to the prolonged cold of winter, or by an artificial equivalent. After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually flower. The term is sometimes used to refer to the need of herbal (non-woody) plants for a period of cold dormancy in order to produce new shoots and leaves, but this usage is discouraged. Many plants grown in temperate climates require vernalization and must experience a period of low winter temperature to initiate or accelerate the flowering process. This ensures that reproductive development and seed production occurs in spring and winters, rather than in autumn. The needed cold is often expressed in chill hours. Typical vernalization temperatures are between 1 and 7 degrees Celsius (34 and 45 degrees Fahrenheit). For many perennial plants, such ...

Blanching (horticulture)
Blanching is a technique used in vegetable growing. Young shoots of a plant are covered to exclude light to prevent photosynthesis and the production of chlorophyll, and thus remain pale in color. Different methods used include covering with soil (hilling or earthing up) or with solid materials such as board or terracotta pots, or growing the crop indoors in darkened conditions. Blanched vegetables generally tend to have a more delicate flavor and texture compared to those that are not blanched, but blanching can also cause the vegetables to be lower in vitamin A. Examples Vegetables that are usually blanched include:MM. Vilmorin-Andrieux; W.Robinson. 1885/undated.

Telegraph Media Group
Telegraph Media Group Limited (TMG; previously the Telegraph Group) is the proprietor of ''The Daily Telegraph'' and ''The Sunday Telegraph''. It is a subsidiary of Press Holdings. David and Frederick Barclay acquired the group on 30 July 2004, after months of intense bidding and lawsuits, from Hollinger Inc. of Toronto, Canada, the newspaper group controlled by the Canadian/American businessman Conrad Black. In 2015, TMG made an operating profit of £51 million. Profits before tax were £47m, and turnover for the 53 weeks up to 3 January 2016 was £319m, according to unaudited accounts leaked to ''The Guardian''. If these figures are accurate, then this was an increase from 2014 levels on both accounts. Telegraph Media Group operates as a multimedia news company. The holding publishes daily and weekly publications in printed and electronic versions, which provide news on politics, obituaries, sports, finance, lifestyle, travel, health, culture, technology, fashion and cars.

Telegraph
Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined and such systems are thus not true telegraphs. The earliest true telegraph put into widespread use was the optical telegraph of Claude Chappe, invented in the late 18th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era. The electric telegraph started to replace the optical telegraph in the mid-19th century. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph, initially used mostly as an aid to railway signalling. Th ...

Rhubarb Forcer
Rhubarb forcers are bell-shaped pots with a lidded opening at the top, used to cover rhubarb to limit photosynthesis. They encourage the plant to grow early in the season and also to produce blanched stems. The pots are placed over two- to three-year-old rhubarb crowns during winter or very early spring. Once shoots appear the lid is taken off, causing them to grow towards the light. Around high and wide without the lid, they are traditionally made of terracotta but can be as simple as an upside down plastic bucket.

European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act ...

Protected Designation Of Origin
The protected designation of origin (PDO) is a type of geographical indication of the European Union and the United Kingdom aimed at preserving the designations of origin of food-related products. The designation was created in 1992 and its main purpose is to designate products that have been produced, processed and developed in a specific geographical area, using the recognized know-how of local producers and ingredients from the region concerned. The list below also shows other geographical indications. Features The characteristics of the products protected are essentially linked to their terroir. The European or UK PDO logo, of which the use is compulsory, documents this link. European Regulation 510/2006 of 20 March 2006 acknowledges a priority to establish a community protection system that ensures equal conditions of competition between producers. This European Regulation is intended to guarantee the reputation of regional products, adapt existing national protections t ...

Candle
A candle is an ignitable wick embedded in wax, or another flammable solid substance such as tallow, that provides light, and in some cases, a fragrance. A candle can also provide heat or a method of keeping time. A person who makes candles is traditionally known as a chandler. Various devices have been invented to hold candles, from simple tabletop candlesticks, also known as candle holders, to elaborate candelabra and chandeliers. For a candle to burn, a heat source (commonly a naked flame from a match or lighter) is used to light the candle's wick, which melts and vaporizes a small amount of fuel (the wax). Once vaporized, the fuel combines with oxygen in the atmosphere to ignite and form a constant flame. This flame provides sufficient heat to keep the candle burning via a self-sustaining chain of events: the heat of the flame melts the top of the mass of solid fuel; the liquefied fuel then moves upward through the wick via capillary action; the liquefied fuel finally ...

Rhubarb
Rhubarb is the fleshy, edible stalks ( petioles) of species and hybrids (culinary rhubarb) of ''Rheum'' in the family Polygonaceae, which are cooked and used for food. The whole plant – a herbaceous perennial growing from short, thick rhizomes – is also called rhubarb. Historically, different plants have been called "rhubarb" in English. The large, triangular leaves contain high levels of oxalic acid and anthrone glycosides, making them inedible. The small flowers are grouped in large compound leafy greenish-white to rose-red inflorescences. The precise origin of culinary rhubarb is unknown. The species ''Rheum rhabarbarum'' (syn. ''R. undulatum'') and '' R. rhaponticum'' were grown in Europe before the 18th century and used for medicinal purposes. By the early 18th century, these two species and a possible hybrid of unknown origin, ''R.'' × ''hybridum'', were grown as vegetable crops in England and Scandinavia. They readily hybridize, and culinary rh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhubarb Triangle
The Rhubarb Triangle is a area of West Yorkshire, England between Wakefield, Morley and Rothwell famous for producing early forced rhubarb. It includes Kirkhamgate, East Ardsley, Stanley, Lofthouse and Carlton. The Rhubarb Triangle was originally much bigger, covering an area between Leeds, Bradford and Wakefield. From the 1900s to 1930s, the rhubarb industry expanded and at its peak covered an area of about . Rhubarb is native to Siberia and thrives in the wet cold winters in Yorkshire. West Yorkshire once produced 90% of the world's winter forced rhubarb from the forcing sheds that were common across the fields there. In 2010, Yorkshire Forced Rhubarb was awarded Protected Designation of Origin (PDO) status by the European Commission’s Protected Food Name scheme after being recommended by Department for Environment, Food and Rural Affairs (Defra). Cultivation The cultivation method for forced rhubarb was developed in the early 1800s. The fields were fertilised with l ...
