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°....
