Prelims 2014 · Science and Technology · Question 47
Which of the following statements is/are correct regarding vegetative propagation of plants?
- Vegetative propagation produces clonal population.
- Vegetative propagation helps in eliminating the virus.
- Vegetative propagation can be practiced most of the year.
Select the correct answer using the code given below.
Answer
1 and 3 only
1. Vegetative propagation produces clonal population. — Correct. New plants arise from somatic parts of a single parent, so they are genetically identical clones.
2. Vegetative propagation helps in eliminating the virus. — Incorrect. Ordinary vegetative propagation usually transmits the same viral infection from parent to offspring; virus elimination is done through special methods like meristem culture, not vegetative propagation itself.
3. Vegetative propagation can be practiced most of the year. — Correct. Since it does not depend on flowering, pollination, or seed set, many vegetative methods can be carried out through much of the year under suitable conditions.
Hence, statements 1 and 3 only are correct.
