Seed heads may form under different conditions depending on species.

• A. Could be any of these depending on species
• B. Only under drought
• C. Only after mowing
• D. Only in winter

Answer: (A)

Seed heads arise from the plant’s reproductive cycle, and different turf species have different triggers for flowering. Because each species responds to its own combination of growth stage, environmental cues, and stress signals, there isn’t a single condition that will cause seed heads in every grass. Some species may head after mowing as they shift resources to reproduction, others may produce seed heads under drought stress, and still others may head in winter or under specific day-length or temperature cues. This variability means seed heads can form under a range of conditions, depending on the species.
