Yvonne Aitken
Yvonne Aitken (17 October 1911 – 29 November 2004) was an Australian agricultural scientist whose contributions to the field included studies of plant flowering as it depends on climate, season, and genetic factors. She was appointed as a Member of the Order of Australia in 1989. Aitken's primary goal was to produce a greater range of consumable crops. By comparing flowering data for particular plant varieties across various latitudes, and under laboratory conditions, Aitken deduced fundamental factors that governed the transition of plants from the vegetative to reproductive states. In general, those plants flowering earliest under given conditions had the least dependence on climate whereas later-flowering varieties reacted strongly to the climate setup. Background and personal life Aitken was born on 17 October 1911 in Horsham, Victoria to David Aitken and Arabella Miller. She was the eldest of two children. Aitken was educated at the Convents of Mercy in the town in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Science
Agricultural science (or agriscience for short) is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture. Professionals of the agricultural science are called agricultural scientists or agriculturists. History In the 18th century, Johann Friedrich Mayer conducted experiments on the use of gypsum (hydrated calcium sulphate) as a fertilizer.John Armstrong, Jesse Buel. ''A Treatise on Agriculture, The Present Condition of the Art Abroad and at Home, and the Theory and Practice of Husbandry. To which is Added, a Dissertation on the Kitchen and Garden.'' 1840. p. 45. In 1843, John Bennet Lawes and Joseph Henry Gilbert began a set of long-term field experiments at Rothamsted Research in England, some of which are still running as of 2018. In the United States, a scientific revolution in agriculture began with the Hatch Act of 1887, which used the term " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinity College (University Of Melbourne)
Trinity College is the oldest residential college of the University of Melbourne, the first university in the colony of Victoria, Australia. The college was opened in 1872 on a site granted to the Church of England by the government of Victoria. In addition to its resident community of 380 students, mostly attending the University of Melbourne, Trinity's programs includes the Trinity College Theological School, an Anglican training college that is a constituent college of the University of Divinity; and the Pathways School, which runs Trinity College Foundation Studies, preparing international students for admission to the University of Melbourne and other Australian tertiary institutions, as well as summer and winter schools for young leaders and other short courses. History Trinity College was founded in 1870 by the first Anglican Bishop of Melbourne, Charles Perry. Students were in residence from 1872, the first being John Francis Stretch.

Melbourne University Press
Melbourne University Publishing (MUP) is the book publishing arm of the University of Melbourne. History MUP was founded in 1922 as Melbourne University Press to sell text books and stationery to students, and soon began publishing books itself. Over the years scholarly works published under the MUP imprint have won numerous awards and prizes. The name ''Melbourne University Publishing'' was adopted for the business in 2003 following a restructure by the university, but books continue to be published under the ''Melbourne University Press'' imprint. The Miegunyah Press is an imprint of MUP, established in 1967 under a bequest from businessman and philanthropist Russell Grimwade, with the intention of subsidising the publication of illustrated scholarly works that would otherwise be uneconomic to publish. Grimwade's great-grandnephew Andrew Grimwade is the present patron. ''Miegunyah'' is from an Aboriginal Australian language, meaning "my house".

Royal Society Of Victoria
The Royal Society of Victoria (RSV) is the oldest scientific society in the state of Victoria in Australia. Foundation In 1854 two organisations formed with similar aims and membership, these being ''The Philosophical Society of Victoria'' (founded 15 June, 1854, inaugural president Andrew Clarke) and ''The Victorian Institute for the Advancement of Science'' (founded 12 August, 1854, inaugural president Justice Sir Redmond Barry). These two merged in July 1855 to form the Philosophical Institute of Victoria, with Clarke as the inaugural president. The Philosophical Institute received Royal Charter in 1859, and the first president of the freshly renamed Royal Society of Victoria was Ferdinand von Mueller (later Baron Sir Ferdinand von Mueller), then Victoria's Government Botanist. In 1860 the RSV organised the ill-fated Burke and Wills expedition under the Presidency of Victorian Governor Sir Henry Barkly. Activities The Society has played an important role in the life of Mel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photoperiodism
Photoperiodism is the physiological reaction of organisms to the length of night or a dark period. It occurs in plants and animals. Plant photoperiodism can also be defined as the developmental responses of plants to the relative lengths of light and dark periods. They are classified under three groups according to the photoperiods: short-day plants, long-day plants, and day-neutral plants. Plants Many flowering plants (angiosperms) use a photoreceptor protein, such as phytochrome or cryptochrome, to sense seasonal changes in night length, or photoperiod, which they take as signals to flower. In a further subdivision, ''obligate'' photoperiodic plants absolutely require a long or short enough night before flowering, whereas ''facultative'' photoperiodic plants are more likely to flower under one condition. Phytochrome comes in two forms: Pr and Pfr. Red light (which is present during the day) converts phytochrome to its active form (pfr). This then triggers the plant to grow. ...

Trifolium Subterraneum
''Trifolium subterraneum'', the subterranean clover (often shortened to sub clover), subterranean trefoil, is a species of clover native to Europe, Southwest Asia, Northwest Africa and Macaronesia. The plant's name comes from its underground seed development (geocarpy), a characteristic not possessed by other clovers. It can thrive in poor-quality soil where other clovers cannot survive, and is grown commercially for animal fodder. There are three distinct subspecies used in agriculture, each with its own ideal climate and soil type, allowing for wide distribution of the plant over varied environments. * ''T. subterraneum'' subsp. ''subterraneum'' is the generalist subspecies, and it can be grown in the widest range of environments. * ''T. subterraneum'' subsp. ''yanninicum'' is grown in moist areas that are prone to flooding. * ''T. subterraneum'' subsp. ''brachycalycinum'' is a more sensitive plant, requiring dry, cracked soil for its germination. Some systematists consider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
