What is vernalisation????

1.	What is vernalisation????
Answer» Vernalisation is defined as the qualitative or quantitative dependence of plants on\xa0exposure to a low temperature to flower. Temperature affects flowering, metabolic activities, and germination of seeds in plants.Example: Food plants such as wheat and barley have a ‘spring variety’ and a ‘winter variety’. The ‘spring variety’ is usually planted in the spring season. As a result, it flowers and produces grains by the end of the growing season. The ‘winter variety’, however, is planted in autumn. It germinates over winter, grows in the spring and is harvested in summer. In contrast to the spring variety, the winter variety will not flower or produce grains within the flowering season if planted in spring. Vernalization can be defined as the requirement of low temperature for flowering.
