Biology Question on Plant Growth Regulators
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
in long day plants under short day conditions
Explanation
Solution
When long day plants are grown under short day conditions, the 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.
