Frequently Asked Questions
No. Needing a cold winter (vernalisation) is a response to prolonged cold. Thermoperiodism refers specifically to regular, daily (diurnal) temperature cycles.
No. It is a specific adaptation found in certain species, often those from environments with significant daily temperature ranges. Many plants are relatively athermoperiodic.
Yes, advanced gardeners and commercial growers sometimes manipulate day/night temperatures (DIF) to control plant height, flowering time, and quality, applying principles of thermoperiodism.
Thermoperiodism is a response to a cycle of temperatures over time. Thermotropism is a directional growth response (bending) towards or away from a heat source at a given moment.
