Which term describes an abnormal reduction in plant growth?

• A. Root Knot
• B. Stunting
• C. Fungi
• D. Die Back

Answer: (B)

Recognizing the term for reduced plant growth: when a plant remains smaller than normal and shows less vigor than healthy plants, that condition is called stunting. It reflects a slowdown or inhibition of growth processes such as cell division, cell expansion, and biomass accumulation due to stresses like nutrient deficiencies, drought, root damage, or viral infections. The result is a plant with shorter stems, smaller leaves, and overall reduced size, even if the remaining tissue is green and intact. Die back describes tissue dying from the tips or older parts, not a general reduction in growth. Root knot points to a specific nematode-caused disease that disrupts roots and can lead to poor growth, but it’s not the general term for a growth reduction. Fungi refer to a broad group of organisms, not a description of growth behavior.
