Question

Pineapple can be made to produce fruits throughout the year by application of

• A. IAA, IBA
• B. NAA, 2, 4-D
• C. Phenyl acetic acid
• D. Cytokinins

Answer 1

The correct option is A IAA, IBA

Auxin is a plant hormone. It usually inhibits flowering. However, it promotes flowering in pineapple. IAA (indoleacetic acid) and IBA (indolebutyric acid) are naturally occurring type of auxin hormone. These hormones promote fruit production in pineapple throughout the year. It is also used for synchronizing fruit set.

Thus, the correct answer is 'IAA, IBA'.
