Question

Gibberellic acid induces flowering

• A. In some gymnospermic plants only
• B. In long day plants under short day conditions
• C. In short day plants under long day conditions
• D. In day-neutral plants under dark conditions

Answer 1

The correct option is B

In long day plants under short day conditions

When long day plants are grown under short day conditions, gibberellins are produced in insufficient quantities and flowering does not occur. However, if the plant is transferred to long day conditions, or gibberellin solution is applied to leaves, flowering occurs.
