Question

Parthenocarpic fruits can be produced by

• A. treating the plants with gibberellic acid.
• B. None of these.
• C. raising the plants from vernalized seeds.
• D. treating the plants with phenyl mercuric acetate.

Answer 1

The correct option is A

treating the plants with gibberellic acid.

When sprayed on flowers, any of the plant hormones gibberellin, auxin and cytokinin could stimulate the development of parthenocarpic fruit.
Parthenocarpic fruits are seedless as they are formed without fertilisation.

Treating plants with phenyl mercuric acetate reduces the rate of transpiration.

Vernalization is the exposure of the plant to low temperature in order to stimulate flowering.
