FAQ

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.

The response of an organism to regular, daily fluctuations in temperature.

Thermoperiodism is usually technical/scientific in register.

Thermoperiodism: in British English it is pronounced /ˌθɜː.məʊˈpɪə.ri.ə.dɪ.zəm/, and in American English it is pronounced /ˌθɝː.moʊˈpɪr.i.ə.dɪ.zəm/. Tap the audio buttons above to hear it.

Memory Aids

Mnemonic

Think: THERMO (heat) + PERIOD (a cycle) + ISM (a process). It's the 'ism' or process of responding to heat cycles.

Conceptual Metaphor
