Parthenocarpic tomato fruits can be produced by:
- removing androecium of flowers before pollen grains are released
- treating the plants with low concentrations of gibberellic acid and auxins
- raising the plants from vernalized seeds
- treating the plants with phenylmercuric acetate
The Correct Option is B
Solution and Explanation
Parthenocarpic fruits are those that develop without fertilization, and hormonal treatments like gibberellic acid and auxins can induce this phenomenon in plants like tomatoes. These treatments stimulate fruit development without the need for pollination and fertilization.
So, the correct option is (B): treating the plants with low concentrations of gibberellic acid and auxins

Sexual Reproduction in Flowering Plants
Sexual reproduction in flowering plants takes place or happens when the production of a new organism occurs from two parents by making use of their gametes or sex cells. Both sexual and asexual reproduction can be found in plants. Nearly all flowering plants reproduce sexually. Flowers play a captious role in the process as it carries both the male and female reproductive parts commonly known as androecium and gynoecium respectively.
An individual flower comprises the following parts -
- Pedicle
- Calyx
- Petals
- Sepals
- Stamen
- Pistil
- Receptacle
