photoperiodism-and-vernalisation
The photoperiodism-and-vernalisation process occurs when a plant’s growth is influenced by the length of the light period it receives each day. This process is usually broken into two categories: vernalisation and photoperiodism.
Vernalisation is the process that a plant undergoes to become winter-hardy. This is usually done by exposing the plant to cold temperatures for a period of time. Photoperiodism is the process that a plant undergoes in response to the length of the light period it receives each day. This process can be used to determine the time of year that a plant will flower.
