Girdling injuries can be caused by which of the following?

• A. Ropes
• B. Wires
• C. Roots
• D. All of the above

Answer: (D)

Girdling injuries occur when something forms a complete ring around a plant part, cutting off the movement of water and nutrients between roots and shoots. A rope or wire left around a trunk or branch can tighten as the plant grows, constricting bark and cambium and eventually blocking flow. Roots can also encircle the base or stem, creating a tight belt that restricts vascular transport. Since rope, wire, and encircling roots can each create that continuous ring and disrupt plant tissues, all of the above is the best answer.
