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: Understand plant propagation methods.
Plant propagation can be done through sexual methods (seeds) or asexual/vegetative methods (tubers, corms, bulbs, cuttings, etc.).
Step 2: Recall the propagation method for Marigold.
Marigold (Tagetes species) is an annual flowering plant that is primarily propagated through seeds. It grows easily from seeds and flowers within a short period.
Step 3: Analysis of each option.

• (A) Tubers: Incorrect. Tubers (like potato) are swollen underground stems used for vegetative propagation. Marigold does not produce tubers.
• (B) Corms: Incorrect. Corms (like gladiolus) are swollen underground stems that store food. Marigold does not produce corms.
• (C) Bulbs: Incorrect. Bulbs (like onion, garlic) are underground storage organs with fleshy leaves. Marigold does not produce bulbs.
• (D) Seeds: Correct.} Marigold is commonly and easily propagated through seeds. It produces abundant seeds that germinate readily.

Step 4: Conclusion.
Marigold is an annual plant that completes its life cycle in one season and reproduces primarily through seeds. While some varieties can be propagated through cuttings, the most common and primary method is by seeds. Final Answer:} (D) Seeds
