Webb21 apr. 2012 · The plant initiates flowering in response to leaf signals when leaves detect equal periods of light and darkness (photoperiodism). This stimulus is combined with temperature changes (thermoperiodism) in the fall: a cold snap after the equinox can help stimulate flowering. Spring crops are normally much smaller that the fall crop. http://www.eagri.org/eagri50/PPHY261/lec15.pdf
WebbOther plants require only a short night to flower. These are termed “long-day” plants. These bloom only when they receive more than 12 hours of light. Many of our summer-blooming flowers and garden vegetables are long-day plants, such as asters, coneflowers, California poppies, lettuce, spinach and potatoes. What is Thermoperiodism in plants?
