Gum spots in cherry veneer are caused by which factors?

Gum spots in cherry veneer are caused by which factors?

• A. Insect attacks, particularly from peach bark beetles, and undisturbed stands of trees.
• B. Prolonged drought and sunscald.
• C. Soil nutrient deficiency.
• D. High humidity during harvest.

Answer: (A)

Gum spots in cherry veneer come from the tree’s defensive resin flow in response to wounding, most often from bark beetle activity. Peach bark beetles bore into the bark of cherry, creating wounds that trigger resin (gum) exudation to seal the entry. When stands are undisturbed, pest populations can build up, leading to more trees developing this gum around the damage. While drought, sunscald, soil nutrient issues, or high humidity at harvest can stress trees or affect quality in other ways, they don’t explain the specific gum formation as directly as insect attack, especially by peach bark beetles, in unmanaged stands.
