Question
‘Fertilisation is not an obligatory event for fruit production in certain plants’. Explain the statement.
✓
Answer
This can be observed in parthenocarpic fruits. The ‘seedless fruits’ that are available in the market, such as pomegranate, grapes, etc., are good examples. Flowers of these plants are sprayed by a growth hormone that induces fruit development even though fertilisation has not occurred. The ovules of such fruits, however, fail to develop into seeds.
