Question

Gibberellin stimulates flowering in

• A. The plants growing in Japanese farms
• B. The short day plants
• C. The long day plants
• D. Day neutral plants

Answer 1

Answer: (C)

The long day plants

Gibberellins are hormones involved in many normal plant functions. Gibberellins affect several reproductive processes in plants. They stimulate flowering, particularly in long-day plants.

In addition, gibberellins substitute for the low temperature that biennials require before they begin flowering. If gibberellins are applied to biennials during their first year of growth, flowering occurs without exposure to a period of low temperature.

Thus, the correct answer is option C.
