Question

Artificial application of auxins like IAA, IBA, and NAA to unpollinated pistils can form

• A. fruits with much flesh
• B. larger fruits
• C. sweet fruits
• D. seedless fruits

Answer 1

Answer: (D)

seedless fruits

NAA and 2, 4-D is often employed for inducing flowering in litchi and pineapple.

Application of auxins (e.g., IAA, IBA) and conjugate auxins (e.g., IBA-alanine) to unpollinated pistils make them develop into seedless fruits (or parthenocarps) which carry a better market price than the normal fruits having seeds.

So the correct answer is 'seedless fruits'.
