Parthenocarpic tomato fruits can be produced by

  • A
    treating the plants with phenylmercuric acetate
  • B
    removing androecium of flowers before pollen grains are released.
  • Correct answer
    C
    treating the plants with low concentrations or gibberellic acid and auxins
  • D
    raising the plants from vernalized seeds

Solution

Seedless fruits are produced by parthenocarpy. It can be artificially induced by the application of plant hormones such as auxin and GA. Removal of androecium, before pollen release is called emasculation which is helpful in preventing unwanted pollination. Vernalized seeds are the chill treated seeds for breaking dormancy. Phenyl mercuric acetate is an anti-transpirant.

Hence, the correct answer is option: 'C'.
