Q. 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
Explanation
[Solution from source] Auxins and gibberellins can make the ovary grow into a fruit without fertilisation, giving seedless (parthenocarpic) tomatoes. Removing the androecium alone only stops pollination; without a hormone stimulus the flower would simply drop. Answer (2).
