What term describes the persistent base of a perennial herbaceous grass?

• A. Crown
• B. Decline
• C. Dicot
• D. Defoliation

Answer: (A)

The persistent base of a perennial herbaceous grass is the crown. The crown sits at or just below the soil surface and contains the meristematic tissue that generates new shoots (tillers) and roots each growing season. It also stores carbohydrates, giving the plant energy to regrow after mowing, grazing, drought, or cold stress. Because the crown endures year after year while the foliage dies back, it’s described as the plant’s persistent base. This is different from other terms you might hear. A dicot is a broadleaf plant type, not a grass structure. Defoliation refers to the act of removing leaves, not a plant part. Decline describes a phase of reduced vigor, not a specific anatomical feature. Keeping the crown healthy is crucial for turf recovery; damage to the crown can slow or prevent regrowth because the growth points and energy reserves are located there.
