What is the term used for yellowing of leaf tissue due to a lack of chlorophyll?

The term used for the yellowing of leaf tissue due to a lack of chlorophyll is known as "Chlorosis." In this context, the specific type indicated, "Fe Chlorosis," refers to iron chlorosis, which is often a result of inadequate iron availability to the plant. When a plant does not receive enough iron, it cannot produce sufficient amounts of chlorophyll, the green pigment essential for photosynthesis, leading to the yellowing of the leaves.

Chlorosis is a common issue in many crops and can arise from various factors such as nutrient deficiencies, poor soil conditions, or pH levels that affect nutrient availability. In contrast, leaf spotting, fungal wilt, and stunted growth relate to different plant health issues not primarily associated with chlorophyll deficiency, thus differentiating them from the process of chlorosis.
