Prelims 2014 · Science and Technology · Question 47
Which of the following statements is/are correct regarding vegetative propagation of plants? 1. Vegetative propagation produces clonal population. 2. Vegetative propagation helps in eliminating the virus. 3. 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.
