Advantages & Disadvantages of Asexual Propagation (Vegetative Propagation)
Advantages of Asexual Propagation or Vegetative Propagation:
1. Plants grow faster and mature earlier since they acquire the age of the parent plant.
2. Seed dormancy problems are eliminated completely.
3. They are more resistant to disease and pests.
4. Some parts have no seeds, so they can only be propagated vegetatively.
5. Crops can survive adverse weather and soil conditions.
6. Failure of fertilization is avoided.
7. Desirable characters are retained.
Disadvantages of Asexual Propagation or Vegetative Propagation:
1. Plants may not live long.
2. It involves a lot of time.
3. The planting materials are usually bulky and can transmit diseases.
4. Grafting and budding require special skills.
5. There is no genetic variability, so it cannot be used to achieve crop improvement.
6. It is not easily stored.
