How does wind injure plants?

• A. Sand Abrasion At Soil Line.
• B. Vase-Like Growth Due To Drought.
• C. Increased Root Nodulation.
• D. Enhanced Photosynthesis.

Answer: (A)

Wind injury happens mainly from mechanical abrasion by wind-blown sand and grit, which wears away the plant’s surface where growth is most exposed. At the soil line, emerging tissues and young stems are especially vulnerable, so sand striking those areas can scratch and remove the outer protective layers, causing wounds, scarring, and dehydration. These damages can slow growth and open the plant to disease because the damaged tissue is easier for pathogens to enter and because water loss increases when the surface is compromised. The other descriptions don’t fit wind injury. Drought-related vase-like growth describes a response to water stress, not a mechanical abrasion from wind. Increased root nodulation is a nodulation response in legumes to fix nitrogen, unrelated to wind damage. Enhanced photosynthesis would require favorable conditions and generally isn’t associated with wind injury; wind typically hinders photosynthesis by damaging tissues and increasing water loss.
