Minimum temperature required for bud initiation in thermosensitive chrysanthemum cultivars is:

Correct option is C

• Below 16°C → Bud initiation is delayed.

• At 16°C → Ideal temperature for bud initiation.

• Above 16°C (e.g., 27°C) → Promotes vegetative growth, delaying flower formation.

• Chrysanthemums are short-day plants, requiring shorter daylight hours for flowering.

• Thermosensitive cultivars are influenced by temperature changes in their bud formation.

• Optimal temperature for flowering is 15–22°C.

• High temperatures reduce flower quality, while very low temperatures delay bud formation.
