  9. Flowering is a form of PhotoperiodismIt is controlled by Critical Night Length = CNL • If the daytime period is broken by a brief exposure to darkness, then there is noeffect on flowering. • If the night-time period is broken by a short exposure to light, photoperiod responses are disrupted and plants do not flower. • Short-day plants flower if night is longer than CNL. • Long-day plants flower if night is shorter than CNL.

  10. To Flower: Short-Day Plants need a night longer than its CNL. Long-Day Plants need a night shorter than its CNL. CNL = 14 hrs CNL = 8 hrs No Yes Yes No No Yes
