VERNALIZATION- (Chilling treatment)
VERNALIZATION It was found by Lysenko (1928), a Russian worker that the cold requiring yearly and biennial plants can be made to blossom in one developing season by giving low-temperature treatment to youthful plants or dampened seeds. He called the impact of this chilling treatment as vernalization. Vernalization is, hence, a cycle of shortening of the adolescent or vegetative stage and rushing blossoming by past cool treatment. Some plants expect the presentation to a low temperature, 0 to 10°C, for a couple of days to half a month for blooming. Such acceptance of blooming by a low temperature is called vernalization SITE FOR VERNALIZATION The boost of vernalization is seen simply by the meristematic cells (active apical meristem). e.g.- shoot tip, incipient organism tips, root summit, creating leaves, and so on Necessities OF VERNALIZATION (i) Low Temperature : Low temperature needed for vernalization is typically 0°—5°....
