Question

Traditional method of artificial propagation in plants is done by _____.

• A. Bulbs
• B. Rhizome
• C. Tuber
• D. Grafting

Hint:

Natural propagation: Bulb, rhizome, tuber Artificial propagation: Cutting, layering, grafting

Answer 1

The Correct Option is D

Concept: Artificial propagation is the process in which humans deliberately grow new plants from existing plants using special techniques. Some common methods of artificial vegetative propagation are:
• Cutting
• Layering
• Grafting
• Tissue culture

Step 1: Understanding grafting. Grafting is a traditional artificial propagation technique in which:
• The stem portion of one plant (scion)
• is attached to the rooted portion of another plant (stock) Both parts grow together as a single plant. Thus, grafting is considered a traditional method of artificial propagation. Therefore: \[ \boxed{\text{Grafting}} \]

Step 2: Why other options are incorrect.
• Option (1) Bulbs: Bulbs are natural vegetative structures.
• Option (2) Rhizome: Rhizome is an underground stem and represents natural propagation.
• Option (3) Tuber: Tubers are modified underground stems involved in natural vegetative reproduction. Only grafting is an artificial method performed intentionally by humans. Hence, the correct answer is: \[ \boxed{(4)\ \text{Grafting}} \]
