Which symptom may appear upon regrowth after frost injury?

• A. Regrowth has ragged leaf margins/holes in leaves.
• B. Regrowth shows perfectly smooth margins.
• C. Regrowth appears as new roots only.
• D. Regrowth produces more branches with no leaves.

Answer: (A)

Frost damage disrupts and kills tissue, especially at the leaf margins. When regrowth starts from protected meristems, the new leaf tissue often emerges unevenly, leading to jagged, ragged edges or holes where tissue didn’t recover evenly. That irregular margin is a common visible sign of frost-influenced regrowth. Smooth margins would suggest healthy, undamaged growth; regrowth that is only roots or branches with no leaves doesn’t reflect the typical leaf regrowth pattern after frost injury.
