Parthenocarpic tomato fruits can be produced by
Options
- Atreating the plants with phenylmercuric acetate
- Bremoving androecium of flowers before pollen grains are released.
- Ctreating the plants with low concentrations or gibberellic acid and auxins
- Draising the plants from vernalized seeds
Correct answer
C. treating the plants with low concentrations or gibberellic acid and auxins
Step-by-step 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.
