Question

Parthenocarpic tomato fruits can be produced by:

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

Answer 1

Answer: (B)

treating the plants with low concentrations of gibberellic acid and auxins

Answer 2

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
