Which term identifies how chrysanthemums are induced to flower?

• A. Pollination
• B. Photoperiodism
• C. Photoflowering
• D. Photorespiration

Answer: (C)

Flowering in chrysanthemums is driven by light duration, a classic photoperiodic response where the plant senses day length and, when the nights reach a critical length, shifts from vegetative growth to flowering. The term used to describe this light-driven induction of flowering is photoflowering, which directly labels the observable outcome—flowering—that results from the plant’s exposure to a specific photoperiod. In other words, photoflowering captures the effect of the light signal on the plant’s reproductive development. While photoperiodism refers to the underlying timing mechanism by day length, and pollination is about pollen transfer, photoflowering best identifies the process by which chrysanthemums are induced to flower through photoperiodic cues.
