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 the 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 vegetative propagated do not need to produce seeds.

Human intervention is responsible for the production or absence of fruits in these plants. The specific purpose for each plant is important to understand the issue:

Rose plants are grown for ornamental purposes. Most varieties of rose also produce a nice fragrance. Rose is grown by vegetative propagation (asexual reproduction method), making seeds and fruit non-essential. Vegetative propagation is a faster process, and hence horticulturists around the world have adopted this technique for growing ornamental plants.

  • Petals in domestically grown varieties of Rose are tightly fit and may not allow pollination
  • Rose plant may not produce a functional egg
  • Rose plants may have abortive ovule
  • They may be self-incompatible
  • There may be internal barriers for pollen tube growth and/or fertilisation

Tomato is produced for its juicy fruit. This requires cultivators to follow a method which enables them to get as many fruits as possible.
