What is the term for the yellowing of leaf veins due to mineral deficiencies?

The yellowing of leaf veins due to mineral deficiencies is referred to as chlorosis. This condition occurs when chlorophyll production is disrupted, often due to inadequate nutrients, such as nitrogen, iron, or magnesium. In chlorosis, the green tissue of the leaves dies off, while the veins may retain their green color for some time, creating a striking contrast that signals the underlying deficiency.

Understanding chlorosis is crucial for arborists as it can help diagnose nutrient deficiencies and determine appropriate interventions to promote the health of trees and plants. Symptoms of chlorosis may vary, with the most common indication being yellowing leaves, which, coupled with the visual retention of color in the veins, makes this diagnosis particularly distinct.
