Answer 1

The plants in the experiment that bloomed are short-day plants because they required a longer period of darkness, measured at 14 hours, to induce flowering.

Step-by-step explanation:

Based on the given experiment where a florist grows shrubs of the same species of woody plant under two distinct light schedules, we can conclude that these plants are likely to be short-day plants. Short-day plants require a longer period of darkness to induce flowering. This is demonstrated by the fact that the set of plants subjected to 9 hours of light followed by 14 hours of dark daily formed flowers, while the set under 15 hours of light did not bloom. The extended period of darkness in the second set's schedule was a significant factor in triggering flowering in these plants.
