John Spence (scientist)
John Arnott Spence (15 July 1929 – 6 March 2013) was a Vincentian-born Trinidadian politician, botanist, and professor emeritus. Spence served as an independent Senator in the Senate of Trinidad and Tobago from 1987 to 2000. Spence was born on 15 July 1929, on the island of Saint Vincent. He moved to Trinidad when he was 11 years old. He attended Queen's Royal College and the University of Bristol, where he obtained his Bachelor of Science in botany in 1951. Spence then completed a post-graduate diploma in Agricultural Science at the University of Cambridge in 1952 and a second diploma in Tropical Agriculture in 1953 from the Trinidad Imperial College of Tropical Agriculture in 1953. He earned a doctorate in 1961 from the University of Bristol. Spence served as the head of the Faculty of Agriculture at the University of the West Indies in Saint Augustine until his retirement in 1989. He then became the head of the Cocoa Research Unit (CRU), which he is credited with its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prof
Professor (commonly abbreviated as Prof.) is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital letter nearly always refers to a full professor. ...

University Of The West Indies
The University of the West Indies (UWI), originally University College of the West Indies, is a public university system established to serve the higher education needs of the residents of 17 English-speaking countries and territories in the Caribbean: Anguilla, Antigua and Barbuda, The Bahamas, Barbados, Belize, Bermuda, British Virgin Islands, Cayman Islands, Dominica, Grenada, Guyana, Jamaica, Montserrat, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Trinidad and Tobago, and Turks and Caicos Islands.

The aim of the university is to help "unlock the potential for economic and cultural growth" in the West Indies, thus allowing improved regional autonomy. The university was originally instituted as an independent external college of the University of London. The university has produced students who have excelled in a number of disciplines such as the arts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trinidad And Tobago Botanists
Trinidad is the larger and more populous of the two major islands of Trinidad and Tobago. The island lies off the northeastern coast of Venezuela and sits on the continental shelf of South America. It is often referred to as the southernmost island in the West Indies. With an area of , it is also the fifth largest in the West Indies. Name The original name for the island in the Arawaks' language was which meant "Land of the Hummingbird". Christopher Columbus renamed it ('The Island of the Trinity'), fulfilling a vow he had made before setting out on his third voyage. This has since been shortened to ''Trinidad''. History Caribs and Arawaks lived in Trinidad long before Christopher Columbus encountered the islands on his third voyage on 31 July 1498. The island remained Spanish until 1797, but it was largely settled by French colonists from the French Caribbean, especially Martinique.Besson, Gerard (2000-08-27).

Pigeon Pea
The pigeon pea (''Cajanus cajan'') is a perennial legume from the family Fabaceae native to the Old World. The pigeon pea is widely cultivated in tropical and semitropical regions around the world, being commonly consumed in South Asia, Southeast Asia, Africa, Latin America and the Caribbean. Etymology and other names Scientific epithet The scientific name for the genus ''Cajanus'' and the species ''cajan'' derive from the Malay word ''katjang'' meaning legume in reference to the bean of the plant. Common English names In English they are commonly referred to as pigeon pea which originates from the historical utilization of the pulse as pigeon fodder in Barbados. The term Congo pea and Angola pea developed due to the presence of its cultivation in Africa and the association of its utilization with those of African descent. The names no-eye pea and red gram both refer to the characteristics of the seed, with no-eye pea in reference to the lack of a hilum on most varieties, u ...

Black Pod Disease
Black pod disease is a protozoal disease of Cocoa trees. This pathogen if left untreated can destroy all yields; annually the pathogen can cause a yield loss of up to 1/3 and up to 10% of total trees can be lost completely. With the value of the cocoa industry throughout the world being so large there are much research and control efforts that go into these ''Phytophthora spp.'' pathogens. This pathogen can be located anywhere on the cocoa trees but is most noted for the black mummified look it will give to the fruit of the cocoa tree. Staying ahead of the pathogen is the best means of control, the pathogen can be greatly reduced if leaf litter is allowed to stay on the ground and if the pathogen gets out of hand chemical control can be used. This pathogen is mostly found in tropical areas where the cocoa trees are located and need rainfall in order to spread its spores. __TOC__ Disease cycle, symptoms and signs The symptom of black pod disease is the necrotic lesion on the ...

Cocoa Pod
''Theobroma cacao'', also called the cacao tree and the cocoa tree, is a small ( tall) evergreen tree in the family Malvaceae. Its seeds, cocoa beans, are used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. The largest producer of cocoa beans in 2018 was Ivory Coast, 2.2 million tons. Description Its leaves are alternate, entire, unlobed, long and broad. Flowers The flowers are produced in clusters directly on the trunk and older branches; this is known as cauliflory. The flowers are small, diameter, with pink calyx. The floral formula, used to represent the structure of a flower using numbers, is ✶ K5 C5 A(5°+52) (5). While many of the world's flowers are pollinated by bees ( Hymenoptera) or butterflies/moths ( Lepidoptera), cacao flowers are pollinated by tiny flies, ''Forcipomyia'' midges in the subfamily Forcipomyiinae. Using the natural pollinator ''Forcipomyia'' midges for ''Theobroma cacao'' was shown to have more fruit production t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are catalytic RNA molecules, called ribozymes. Enzymes' specificity comes from their unique three-dimensional structures. Like all catalysts, enzymes increase the reaction ra ...
