Q: Which of the following statements is / are correct regarding vegetative propagation of plants?
a) Vegetative propagation produces clonal population.
b) Vegetative propagation helps in eliminating the virus.
c) Vegetative propagation can be practiced most of the year
The correct answer is 1 and 3 only.
Vegetative propagation
- This is an asexual method of plant reproduction that occurs in its leaves, roots and stem.
- This is often used when the crop plants either do not produce seeds or when the seeds produced are not viable or are of long dormancy.
- The widespread use of vegetative propagation results in the spread of viruses through propagules such as cuttings, tubers, runners and bulbs. A plant once systemically infected with a virus usually remains infected for its lifetime. Hence, Statement 2 is not correct.
- It can be practised most of the year. Hence, Statement 3 is correct.
- It is a process by which new organisms arise without production of seeds. It helps in development of clones. Hence, Statement 1 is correct.
