Question
Parthenocarpic tomato fruits can be produced by
Options
A.removing androecium of flowers before pollen grains are released
B.terating the plants with low concentrations of gibberellic acid and auxins
C.rsising the plants from vernalized seeds
D.treating the plants with phenylmercuric acetate
Solution
Parthenocarpy is the development of fruits without prior fertilization which results in the forma tion of seedless fruits. In some plant species, parthenocarpic (seedless) fruits may be produced naturally or they may be induced by treatment of the unpollinated flowers with auxin and gibbere llin eg, parthenocarpic tomato fruits can be produced by treating the plants with low concentra tion of gibberellic acid (promotes fruit set) and auxin (completes the development process).
Removal of androecium, before pollen release is called emasculation which is helpful in prevent ing unwanted poor pollination .
Vernalized seeds are the chill treated essds for breaking dormancy.
Phenyl mercuic acetate is an antitranspirant.
