 The cylinders in this experiment represent a 24-hour period. The light area represents light periods during a 24-hr. period and the dark area represents dark periods during a 24-hr. period. The critical length of dark vs. light periods for flowering is depicted by the dotted line. Note that some plants are flowering and some are not flowering. Study the results of this experiment on photoperiodism and flowering to determine whether the following statements are true or false.Short-day plants flower when the day length is longer than the critical length.

Answer the following statement true (T) or false (F)
