Which symptom is indicative of Iron Chlorosis in plants?

Yellow leaves with dark veins are a classic symptom of Iron Chlorosis in plants. This condition often occurs because of insufficient available iron in the soil, which is essential for chlorophyll production. When plants cannot access iron, the younger leaves typically turn yellow while the veins remain dark green, creating a contrast that is characteristic of Iron Chlorosis.

This symptom is particularly noticeable in plants with high nutrient demands or in alkaline soils, where iron becomes less available to plants. The emphasis on the changing color of the leaves versus the veins highlights the deficiency, allowing for easier identification and effective management strategies to address the nutrient imbalance.

The other symptoms listed do not specifically relate to the deficiency of iron. For example, damaged leaf tips can indicate a variety of issues such as drought stress or excess fertilizer, while brown streaks on stems or dark spots on roots may suggest diseases or pest problems rather than a deficiency of iron. Understanding these specific symptoms aids in the accurate diagnosis and treatment of plant health issues.
