A Vavilov Center (of Diversity) is a region of the world first indicated by Nikolai Vavilov to be an original center for the domestication of plants. [4] For crop plants, Nikolai Vavilov identified differing numbers of centers: three in 1924, five in 1926, six in 1929, seven in 1931, eight in 1935 and reduced to seven again in 1940. [5] [6]

[1] 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.
The Institute of Plant Industry was established in 1921 in Leningrad by Nikolai Vavilov who set about to create the world's first and largest collection of plant seeds. . Already in 1916 he did his first collection trip abroad, to Iran, and by 1932 he had collected seeds from almost every country in the world, which by 1933 had made the institute the largest seed bank in the world, with more ...

A corollary of Kasha's rule is the Vavilov rule, which states that the quantum yield of luminescence is generally independent of the excitation wavelength. [4] [7] This can be understood as a consequence of the tendency – implied by Kasha's rule – for molecules in upper states to relax to the lowest excited state non-radiatively.
