Question

The application of synthetic plant hormone, like IAA, IBA and NAA are best described as

• A. Prevent early fruit fall before harvesting and is used to produce parthenocarpic fruit
• B. Prevent early fruit fall only
• C. To produce both seed less fruits and fruits with seeds
• D. To produce large fruit

Answer 1

The correct option is A Prevent early fruit fall before harvesting and is used to produce parthenocarpic fruit

Auxin is a plant hormone (phytohormone). It is used in various processes of plant development. IAA and IBA are naturally occurring auxin hormone. NAA is a synthetic phytohormone. These hormone enhances fruit setting and helps in producing seedless, larger and sweeter fruits. Fruits like orange, banana are produced seedless using these hormones. These hormones also help in early maturing of fruits, thinning of blossoms. They also prevent early fruit fall before harvesting.

Thus, the correct answer is option A.
