Apart from light, the main environmental factor that induces flowering in plants is temperature. Certain plants require specific temperature conditions to trigger the flowering process. This can involve either a specific temperature range or a shift in temperature patterns, such as a change from cooler temperatures to warmer temperatures. Additionally, some plants may require a period of cold temperature exposure, known as vernalization, in order to initiate flowering. Other environmental factors, such as humidity, availability of nutrients, and water availability, may also play a role in flowering, although their exact influence can vary depending on the plant species.
