Explanation

The term vernalization originated from the Latin word Vernalis, which means "of the spring". Vernalization is the artificial exposure of plants (or seeds) to low temperatures to stimulate flowering or enhance seed production. It is the conversion of the winter variety into the spring variety by low-temperature treatment. By satisfying the cold requirement of many temperate-zone plants, flowering can be induced to occur earlier than normal or in warm climates lacking the requisite seasonal chilling. Knowledge of this process has been used to eliminate the normal two-year growth cycle required of winter wheat. By partially germinating the seed and then chilling it to 0° C (32° F) until spring, it is possible to cause winter wheat to produce a crop in the same year.
