What condition in plants is characterized by the loss of green color or yellowing of foliage?

Chlorosis is the condition characterized by yellowing of foliage due to insufficient chlorophyll production within the plant. This impairment can be caused by various factors such as nutrient deficiencies, particularly nitrogen, iron, or magnesium, as well as poor drainage, soil pH imbalances, or root damage. When chlorophyll levels are low, the plant's ability to photosynthesize effectively diminishes, leading to the yellowing appearance of the leaves. Recognizing chlorosis is essential for effective weed and plant management, as it can impact overall plant health and growth if not addressed promptly. In contrast, necrosis refers to the dying or death of tissue, photosynthesis failure is a result of chlorosis, and stunting describes a reduction in growth, which can occur alongside chlorosis but is a separate condition.
