How does vernalisation affect plant development?

Vernalisation is a chilling requirement that certain plants must undergo before they can flower. This process typically involves exposure to cold temperatures over a period of time, which signals to the plant that the conditions are now favorable for reproduction. By experiencing vernalisation, plants are able to synchronize their flowering with the appropriate seasonal changes, ensuring that pollinators are present and that environmental conditions are optimal for seed development.

This ability to regulate flowering times is crucial for the reproductive success of many species, allowing them to take advantage of specific seasons for growth and reproduction, ultimately contributing to their survival and adaptation in their respective environments. Thus, vernalisation plays a key role in the developmental cycles of plants, making the correct answer related to its effect on flowering times.
