Rose plants produce large, attractive bisexual flowers but they seldom produce fruits. On the other hand a tomato plant produces plenty of fruits though they have small flowers. Analyse the reasons for failure of fruit formation in rose.

Both these plants - rose and tomato - both selected by human beings for different characteristics, the rose for its flower and tomato for its fruit. Roses, being vegetatively propagated do not need to produce seeds.

Answer :

Rose plants produce large, attractive bisexual flowers but they seldom produce fruits. On the other hand, a tomato plant produces plenty of fruits though they have small flowers, because of the following possibilities:

1. The pollens produced by the rose plants may not be viable that means they may not have the compatibility to germinate, hence fertilisation does not take place.


2. They may be self-incompatible that means pollen-pistil interaction may not take place.


3. They may have non-functional ovules, that does not produce viable eggs.


4. As the rose plants are hybrid the mitotic division in them may be abnormal, which may produce non-viable gametes.


5. The pollen tubes may have barrier inside of it which restricts the male gamete to reach the ovule.
