Question

why does hibiscus not bears fruits even though androecium and gynoecium present in it?

Answer 1

There can be pollination in hibiscus. But the pollen cannot germinate. If pollen is able to germinate the pollen tube cannot reach to the egg cell to fertilize it. This is called as pollen incompatibility and it occur due to the different biochemical products produced by the biological activity through the pollen incompatibility is mostly due to genetic reasons, it can solved by artificial method Thus it can produced artificial hybrid Variety.

Answer 2

The hibiscus does not bear fruits because the androecium and gynoecium are not working.

Explanation:

• The hibiscus fruits have a five-lobed pod or capsule just below the flower, the lob contains seeds like all other plants. They are no distinct fruits. The identity of the fruit is hidden. Pollination in hibiscus is lost.
• The pollen grains will not germinate. The egg cell cannot fertilize, as the pollen germinates. As a result, the hibiscus does not bear fruits.
