Question

Marigold is propagated by

• A. Tubers
• B. Corms
• C. Bulbs
• D. Seeds

Hint:

Annual flowers like marigold, zinnia, and sunflower are usually propagated by seeds. Perennials are often propagated by vegetative methods like bulbs, corms, or tubers.

Answer 1

The Correct Option is D

Step 1: Understanding the Question
The question asks for the primary method of propagation (reproduction) for the marigold flower.
Step 2: Detailed Explanation
Propagation methods can be sexual (via seeds) or vegetative (via parts of the parent plant like tubers, bulbs, etc.).

Marigold is an annual plant, meaning it completes its life cycle—from germination to producing seeds—within one year, and then dies. The primary and most common method for growing annuals like marigolds is through seeds.

Tubers (e.g., Potato), Corms (e.g., Gladiolus), and Bulbs (e.g., Onion, Tulip) are all forms of vegetative propagation used for other types of plants, not for marigolds.

Step 3: Final Answer
Marigold is propagated by seeds.
