Which statement about vernation in Bermudagrass and Zoysiagrass is true?

• A. Bermudagrass has rolled vernation and Zoysiagrass has folded vernation
• B. Bermudagrass and Zoysiagrass both have rolled vernation
• C. Bermudagrass has folded vernation and Zoysiagrass has rolled vernation
• D. Neither has vernation

Answer: (A)

Vernation describes how a grass blade unfurls as it develops. Bermudagrass produces the leaf roll-up: the leaf emerges as a tight cylinder and then unfolds, which is called rolled vernation. Zoysiagrass, on the other hand, tends to emerge with the blade folded along its length, known as folded vernation. Because these two warm-season grasses show different emergence patterns, the statement that Bermudagrass has rolled vernation and Zoysiagrass has folded vernation is true. This distinct trait helps identify them in the field, whereas alternatives would imply both share the same pattern or that neither has vernation, which isn’t accurate for grasses.
