Question

Which of the following is NOT a method to produce parthenocarpic fruit?
  1. Artificially induced fruit development without pollination and fertilisation
  2. Treating the plants with a low concentration of gibberellic acid and auxins
  3. Naturally occurs without pollination and fertilisation
  4. Removing the androecium of flowers before pollen grains are released


Solution

The correct option is D Removing the androecium of flowers before pollen grains are released
A parthenocarpic fruit is formed without fertilization and is seedless. It is found naturally occurring in plants like banana and can also be artificially induced by treating the plants with suitable phytohormones.

Emasculation or the removal of stamens (androecium) is a method of ensuring that self-pollination does not take place. This is adopted in plant breeding techniques.
