What is the purpose of a grafting tool?

• A. To join two plant tissues
• B. To measure soil pH
• C. To prune branches
• D. To apply fertilizer

Answer: (A)

A grafting tool is used to join two plant tissues in grafting. It makes clean, precise cuts that expose the cambium so the scion and rootstock surfaces can be pressed together with proper alignment. When the cambial layers touch, they can fuse and form a single plant, allowing the vascular system to reconnect and provide nutrients and water to both parts. This precise fit is why grafting tools are designed to cut bevels or wedges that match well. The other tasks listed—measuring soil pH, pruning branches, or applying fertilizer—use different tools like pH meters, pruning shears, and fertilizer spreaders. So the main purpose of a grafting tool is to join two plant tissues by creating the necessary cuts for a successful graft.
