Bermudagrass has folded vernation, and zoysiagrass has rolled vernation. Is this statement true or false?

• A. True
• B. False
• C. Bermudagrass has rolled vernation
• D. Zoysiagrass has folded vernation

Answer: (A)

Vernation describes how a grass blade unfolds as it emerges. There are two common forms: folded vernation, where the blade is folded along its length, and rolled vernation, where the blade is coiled into a tube and then unrolls. Bermudagrass is described as having folded vernation, meaning its new leaves unfold in a flattened, folded arrangement. Zoysiagrass is described as having rolled vernation, with new leaves emerging as a tight cylinder that unrolls. Because the statement aligns with these characteristic emergence patterns for the two species, it is true. In the field, you can observe this by watching a new leaf arise and noting whether it appears flat and folded or cylindrical and unrolling. This trait is a standard diagnostic characteristic used to distinguish warm-season grasses.
