Correct Option
The correct option is 1, 2 and 3 only.
Explanation
Vegetative propagation is a form of asexual reproduction in plants where new individuals arise from vegetative parts such as roots, stems, or leaves, rather than from reproductive organs (seeds). This process produces offspring that are genetically identical to the parent plant.
Statement-wise Analysis
- Statement 1 is Correct: Plants produced through vegetative propagation bypass the initial seed germination and seedling establishment phases. Consequently, they mature faster and produce flowers and fruits earlier than plants grown from seeds.
- Statement 2 is Correct: This method is essential for the multiplication of plants that have lost the capacity to produce viable seeds or produce seeds that are difficult to germinate. Common examples include banana, rose, jasmine, and seedless oranges.
- Statement 3 is Correct: Since vegetative propagation involves mitotic cell division without the fusion of gametes, there is no genetic recombination. The offspring are clones of the parent, ensuring that desirable parental traits are preserved generation after generation.
- Statement 4 is Incorrect: Grapes are widely propagated using vegetative methods, particularly through stem cuttings and layering. This ensures the consistency of fruit quality and variety, which might vary if grown from seeds.
Key Takeaway
Key Takeaway: Vegetative propagation allows for the rapid multiplication of plants, preservation of genetic purity (cloning), and propagation of species that cannot produce viable seeds.
