This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pavlovsk Experimental Station rather than just read about it. In short: Pavlovsk Experimental Station (Russian: Павловская опытная станция) is an agricultural experiment station and gene bank that is part of the Institute of Plant Industry and situated in Pavlovsk near St. Petersburg, Russia.

Key takeaways

Pavlovsk Experimental Station belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Pavlovsk Experimental Station to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Pavlovsk Experimental Station from memory before moving on to harder problems.

Reference excerpt

Pavlovsk Experimental Station (Russian: Павловская опытная станция) is an agricultural experiment station and gene bank that is part of the Institute of Plant Industry and situated in Pavlovsk near St. Petersburg, Russia.

History It was started in 1926 by agricultural scientist Nikolai Vavilov and contains an extensive collection of more than 5,000 varieties of fruits and berries. The Pavlovsk station's collection contains more than 100 varieties each of gooseberries, raspberries, and cherries. It also contains more than 1,000 varieties of strawberries. More than 90% of the collection is found in no other research collection or genebank. The collection is a field genebank, meaning that the varieties are stored as plants in the ground. Most of the species concerned do not breed true from seeds, and so the varieties cannot be stored as seeds. The Pavlovsk station itself fell into German hands during the Siege of Leningrad in 1941–1944, but prior to the arrival of German troops, scientists from the Institute of Plant Industry were able to move much of the station's tuber collection to a location within the city. Twelve of these scientists died of starvation while protecting the institute's edible collection of tubers and seeds. In 2010 the experimental station faced an uncertain future, because the land it sits on was being sold to a developer who planned to build private homes on the site. If this planned development had gone forward, much of the collection would have been lost. Due to technical issues and quarantine regulations, it would not have been feasible to move the collection before demolition of the station was slated to have begun. in 2010 President Dmitry Medvedev announced via Twitter that the issue would be "scrutinised". Prime Minister Vladimir Putin had not yet responded to public calls to save the experimental station and its collection by the end of 2010. However, in April 2012 the Russian government took formal action to preserve this important genetic repository and stop the land from being conveyed to private interests for development.

In popular culture Hunger by American writer Elise Blackwell, is a fictionalized retelling of the plight of the scientists who starved to death while protecting the gene bank's edible seed and tuber collection during the Siege of Leningrad. The song "When the War Came," by the band The Decemberists, tells the story of these scientists, with one verse saying "We made our oath to Vavilov / We'd not betray the Solanum / The acres of asteraceae / To our own pangs of starvation."

Worked examples

Example 1 — a first encounter with Pavlovsk Experimental Station

Start with the simplest possible case. Write down what Pavlovsk Experimental Station claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pavlovsk Experimental Station before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pavlovsk Experimental Station ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pavlovsk Experimental Station

In research: Pavlovsk Experimental Station appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Pavlovsk Experimental Station in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Pavlovsk Experimental Station is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agricultural organizations based in the Soviet Union, Agricultural research stations, Education in Saint Petersburg, so understanding it makes those chapters shorter.
In everyday life: Look for Pavlovsk Experimental Station outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
