What is a possible symptom of sulfur dioxide exposure?

A symptom of sulfur dioxide exposure in plants can indeed be interveinal necrosis. This condition occurs when the areas between the veins of a leaf turn necrotic, or dead, leading to a characteristic pattern of damage. Sulfur dioxide, which is a common air pollutant, can enter plant tissues and create oxidative stress, damaging cells primarily in the leaf. The specific effect of interveinal necrosis is often seen in sensitive plant species, where the chlorophyll in the leaf veins is preserved while the surrounding tissue degrades, causing the typical targeted appearance of the damage.

Recognizing this symptom is crucial for diagnosing air quality influences on plant health and implementing effective pest management strategies. The association between sulfur dioxide exposure and interveinal necrosis highlights the importance of monitoring air quality and understanding its effects on plant physiology.
