Which statement correctly describes vernation differences between bermudagrass and zoysiagrass?

• A. Bermudagrass folded vernation; Zoysiagrass rolled vernation
• B. Bermudagrass rolled vernation; Zoysiagrass folded vernation
• C. Both folded vernation
• D. Both rolled vernation

Answer: (A)

Vernation describes how the leaf blade is arranged in the bud before it emerges, and folded versus rolled are the two main patterns to distinguish species. In bermudagrass, the leaf primordia are folded, so the blade unfurls into a flat, sheets-like leaf. In zoysiagrass, the leaf is rolled up in the bud, so it emerges as a tight, cylindrical form that later unrolls. This difference is a practical field cue: bermudagrass shows folded vernation, while zoysiagrass shows rolled vernation. The statement capturing this contrast is the best description because it reflects how the leaf develops differently in these two grasses, whereas saying both share the same vernation would ignore this recognizable distinction.
