Plant Growth and Development

Vernalisation

Are plants only dependent on light to flower and germinate? Is there any other factor that influences flowering? Yes! In addition to light, another factor that influences flowering in plants is temperature. This dependency on temperature is Vernalisation. Let’s learn this concept and how it affects flowering in plants in more detail

Vernalisation

Vernalisation is defined as the qualitative or quantitative dependence of plants on exposure to a low temperature to flower. Temperature affects flowering, metabolic activities, and germination of seeds in plants.

Plants that grow in mild weather germinate at low temperatures whereas those that grow in hot regions germinate at high temperatures. Some plants need exposure to a low temperature to germinate. Furthermore, a plant can be induced to flower in a growing season by exposing it to low temperature. Therefore, it shortens the vegetative phase and hastens flowering in plants.
