T.D. Lysenko
Trofim Denisovich Lysenko (russian: Трофим Денисович Лысенко, uk, Трохи́м Дени́сович Лисе́нко, ; 20 November 1976) was a Soviet agronomist and pseudo-scientist.''An ill-educated agronomist with huge ambitions, Lysenko failed to become a real scientist, but greatly succeeded in exposing of the “bourgeois enemies of the people.” From such a “scion” who was “grafted” to the Stalinist totalitarian regime “stock”, impressive results could have been expected—and were indeed achieved.'' He was a strong proponent of Lamarckism, and rejected Mendelian genetics in favour of his own idiosyncratic, pseudoscientific ideas later termed Lysenkoism. In 1940, Lysenko became director of the Institute of Genetics within the USSR's Academy of Sciences, and he used his political influence and power to suppress dissenting opinions and discredit, marginalize, and imprison his critics, elevating his anti-Mendelian theories to state-sanc ...

Lamarckism
Lamarckism, also known as Lamarckian inheritance or neo-Lamarckism, is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime. It is also called the inheritance of acquired characteristics or more recently soft inheritance. The idea is named after the French zoologist Jean-Baptiste Lamarck (1744–1829), who incorporated the classical era theory of soft inheritance into his theory of evolution as a supplement to his concept of orthogenesis, a drive towards Evolution of biological complexity, complexity. Introductory textbooks contrast Lamarckism with Charles Darwin's theory of evolution by natural selection. However, Darwin's book ''On the Origin of Species'' gave credence to the idea of heritable effects of use and disuse, as Lamarck had done, and his own concept of pangenesis similarly implied soft inheritance. Many researchers from the 1860s onwards attempted to find evidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Winter Wheat
Winter wheat (usually ''Triticum aestivum'') are strains of wheat that are planted in the autumn to germinate and develop into young plants that remain in the vegetative phase during the winter and resume growth in early spring. Classification into spring wheat versus winter wheat is common and traditionally refers to the season during which the crop is grown. For winter wheat, the physiological stage of heading (when the ear first emerges) is delayed until the plant experiences vernalization, a period of 30 to 60 days of cold winter temperatures (0° to 5 °C; 32–41 °F). Winter wheat is usually planted from September to November (in the Northern Hemisphere) and harvested in the summer or early autumn of the next year. In some places (e.g. Chile) a winter-wheat crop fully 'completes' in a year's time before harvest. Winter wheat usually yields more than spring wheat. So-called "facultative" wheat varieties need shorter periods of vernalization time (15–30 days ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Life Cycle
In biology, a biological life cycle (or just life cycle or lifecycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different "generations" of the species succeed each other during the life cycle. For plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or more), rather than two.Dixon, P.S. 1973. ''Biology of the Rhodophyta.'' Oliver & Boyd. Life cycles that include sexual reproduction involve alternating haploid (''n'') and diploid (2''n'') stages, i.e., a change of pl ...

Ukrainians
Ukrainians ( uk, Українці, Ukraintsi, ) are an East Slavs, East Slavic ethnic group native to Ukraine. They are the seventh-largest nation in Europe. The native language of the Ukrainians is Ukrainian language, Ukrainian. The majority of Ukrainians are Eastern Orthodox Church, Eastern Orthodox Christians. While under the Polish–Lithuanian Commonwealth, the Austrian Empire, and then Austria-Hungary, the East Slavic population who lived in the territories of modern-day Ukraine were historically known as Ruthenians, referring to the territory of Ruthenia, and to distinguish them with the Ukrainians living under the Russian Empire, who were known as Little Russians, named after the territory of Little Russia.

Great Chinese Famine
The Great Chinese Famine () was a period between 1959 and 1961 in the history of the People's Republic of China (PRC) characterized by widespread famine. Some scholars have also included the years 1958 or 1962. It is widely regarded as the deadliest famine and one of the greatest man-made disasters in human history, with an estimated death toll due to starvation that ranges in the tens of millions (15 to 55 million). The most stricken provinces were Anhui (18% dead), Chongqing (15%), Sichuan (13%), Guizhou (11%) and Hunan (8%). The major contributing factors in the famine were the policies of the Great Leap Forward (1958 to 1962) and people's communes, launched by Chairman of the Chinese Communist Party Mao Zedong, such as inefficient distribution of food within the nation's planned economy; requiring the use of poor agricultural techniques; the Four Pests campaign that reduced sparrow populations (which disrupted the ecosystem); over-reporting of grain production; and order ...

People's Republic Of China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Nikolai Vavilov
Nikolai Ivanovich Vavilov ( rus, Никола́й Ива́нович Вави́лов, p=nʲɪkɐˈlaj ɪˈvanəvʲɪtɕ vɐˈvʲiləf, a=Ru-Nikolay_Ivanovich_Vavilov.ogg; – 26 January 1943) was a Russian and Soviet agronomist, botanist and geneticist who identified the centers of origin of cultivated plants. He devoted his life to the study and improvement of wheat, maize and other cereal crops that sustain the global population. Vavilov's work was criticized by Trofim Lysenko, whose anti-Mendelian concepts of plant biology had won favor with Joseph Stalin. As a result, Vavilov was arrested and subsequently sentenced to death in July 1941. Although his sentence was commuted to twenty years' imprisonment, he died in prison in 1943. According to Lyubov Brezhneva, he was thrown to his death into a pit of lime in the prison yard. In 1955 his death sentence was retroactively pardoned under Nikita Khrushchev. By the 1960s his reputation was publicly rehabilitated and he began ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enemies Of The State
An enemy of the state is a person accused of certain crimes against the state such as treason, among other things. Describing individuals in this way is sometimes a manifestation of political repression. For example, a government may purport to maintain national security by describing social or political dissidents as "enemies of the state". In other cases, the individual in question may have in fact endangered the country and its population. Examples Political * In ancient Rome, some parties could be named an enemy of the state through specific public actions resulting in a formally recognized state of war. The Latin term proscription was used for official condemnation of enemies of the state. * The term "enemy of the people" in the Soviet Union during the period of Stalinism. * Communists were considered as enemies of the state in Indonesia since 1965. Displaying communist symbols or attempting to propagate the ideology is considered an act of high treason and terrorism pu ...

Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...
