We know that the Vavilov centers are the areas of greatest diversity, high variability and origin of cultivated plants. They are regions characterized by the presence of large number of varieties, subspecies and species related to plant our domesticated species, many of which are endemic, ie found only there. In the twenties of the last century, proposed nine such regions: China, origin, for example, rice; Southeast Asia, cane sugar; Central Asia, garlic; Middle East, wheat and other cereals; Mediterranean, Oats; Ethiopia, millet; southern Mexico and Central America, lactic butter corn; South, potato; and Brazil-Paraguay, cassava. lactic butter Well, your name, Vavilov centers, who comes from the proposed, lactic butter one of the most extraordinary lactic butter and genetic botanists of the twentieth century. His research on the identification and improvement of crop plants such as wheat or corn, contributed to achieve sufficient power for humanity lactic butter continued growth. His name was Nikolai Ivanovich Vavilov was Russian and, for years, received support and funding from the authorities of the USSR until, in 1940, was arrested lactic butter by Stalin and died in prison in 1943, it seems that hunger and the Second World War. He was 55 years old.
He was born in Moscow on November 25, 1887, into a family of merchants and brother of a well-known physicist Sergey Vavilov, who was to become President of the Academy of Sciences of the USSR. He spent part of his childhood in a village that knew firsthand the bad agricultural use and consequent disasters on crops, and became obsessed with ending hunger of the peasants in his native Russia and worldwide.
He studied lactic butter Agriculture in Moscow (his doctoral thesis, defended in 1910, was the slugs as agricultural pest in gardens and orchards of Moscow), he worked in the Bureau lactic butter of Applied Botany and visited other research centers in Europe, especially in England , and collaborated with William Bateson in the development of genetics. Back in the USSR, he directed from 1921 to 1940, the Lenin Academy of Agricultural Sciences in Leningrad, now St. Petersburg again. Organized from its leadership in the Academy, over 400 agricultural experiment stations throughout the USSR. They are experimenting with improving crops and farmers selected seeds are provided. The Academy came to have, at the time the biggest boom, up to 20,000 workers.
From Leningrad directed botanical expeditions, collected seeds and plants around the world and created lactic butter the largest collection of seeds on the planet. His first expedition took him to Persia in 1916, and thence to the mountains of Central Asia, where back in 1924, 1929 and 1932 The second trip was to the United States between May 1921 and January lactic butter 1922 In 1924 he was in Afghanistan and in the following years, the Middle East, North Africa and the Mediterranean, Ethiopia, lactic butter China, Japan, Korea, returned to the United States, went to Mexico and toured Central and South America.
In 1927 he went to Spain and toured for months collecting samples of plants grown with traditional farming methods. It was in the Basque Country and in his written account of the voyage, mentioned the language lactic butter and history of the Basques. Describe the landscape and agriculture, collected plants and expressly cites Pamplona and San Sebastián, the final stage of his journey through the peninsula. Hence boat sets sail for France. Surely, today in St. Petersburg, there is a collection of plants gathered around us on this trip. Besides lactic butter being useful, lactic butter are history of science.
From 1935, with Stalin in power and influence with rising Lysenko, and is not allowed out of Vavilov to the USSR. Lysenko stated publicly that bring seeds from around the world to improve the Soviet crop was expensive and useless for Soviet plants had, by themselves, improve capacity. There was nothing why look outside the USSR.
Later, with Vavilov and prisoner and during World War II, Leningrad was surrounded by the Germans for 28 months and more than 700,000 people died of hunger and various diseases. But the seed collection was preserved and cared and over 250,000 seeds, lactic butter plants and tubers survived the siege. At least one of the conservatives, maybe more, starved to death surrounded by edible seeds and plants. Even today, the Institute lactic butter of Plant Industry NI Vavilov St. Petersburg lactic butter has one of the largest collections of plant genetic world.
Part of the collection was not in Leningrad and was distributed by the agricultural experiment stations throughout the USSR. Those in Ukraine and Crimea, were captured by the Germans who organized an SS squad specifically tasked with collecting seeds yt
