ANSWERS COMPILED FOR SUCCESSFUL EXAM REVIEW
300 QUESTIONS AND ANSWERS
1. Q: What are the two main categories of turfgrass? A: Cool-season grasses
and warm-season grasses, classified based on their optimal growing
temperatures and seasonal growth patterns.
2. Q: What temperature range do cool-season grasses prefer? A: Cool-
season grasses thrive in temperatures between 60-75°F (15-24°C).
3. Q: Name five common cool-season turfgrasses. A: Kentucky bluegrass,
perennial ryegrass, tall fescue, fine fescue, and bentgrass.
4. Q: What temperature range do warm-season grasses prefer? A: Warm-
season grasses perform best in temperatures between 80-95°F (27-35°C).
5. Q: Name five common warm-season turfgrasses. A: Bermudagrass, Zoysia
grass, St. Augustinegrass, Centipedegrass, and Bahiagrass.
6. Q: What is the difference between rhizomes and stolons? A: Rhizomes are
underground stems that spread horizontally, while stolons are above-ground
stems that spread along the soil surface.
7. Q: Which turfgrass spreads primarily by tillers? A: Perennial ryegrass
and tall fescue spread primarily by tillers (bunch-type growth).
8. Q: What is the crown of a grass plant? A: The crown is the growing point
where shoots and roots originate, located at or just below the soil surface.
9. Q: What are adventitious roots? A: Roots that develop from nodes along
stolons or rhizomes, helping anchor and nourish spreading grass plants.
10. Q: What is thatch in turfgrass? A: Thatch is a layer of dead and living
organic matter that accumulates between the soil surface and green vegetation.
11. Q: At what thickness does thatch become problematic? A: Thatch layers
exceeding ½ inch (12mm) can create problems for water infiltration and root
development.
,12. Q: What causes excessive thatch buildup? A: Over-fertilization,
infrequent deep watering, soil compaction, and poor soil microbial activity.
13. Q: What is the difference between warm-season and cool-season grass
dormancy? A: Cool-season grasses go dormant in extreme heat, while warm-
season grasses go dormant when temperatures drop below 50°F.
14. Q: What is the optimal mowing height for Kentucky bluegrass? A: 2.5-
3.5 inches during growing season, with higher cuts during stress periods.
15. Q: What is the optimal mowing height for Bermudagrass? A: 0.5-2
inches, depending on variety and use (golf greens vs. home lawns).
16. Q: What does C3 photosynthesis mean in turfgrass? A: C3
photosynthesis is the pathway used by cool-season grasses, which is less
efficient in hot temperatures.
17. Q: What does C4 photosynthesis mean in turfgrass? A: C4
photosynthesis is used by warm-season grasses and is more efficient in hot
temperatures and bright sunlight.
18. Q: What is leaf texture in turfgrass evaluation? A: Leaf texture refers to
the width of grass blades, classified as fine, medium, or coarse.
19. Q: Which turfgrass has the finest leaf texture? A: Bentgrass has the
finest leaf texture among common turfgrasses.
20. Q: What is turfgrass density? A: Density refers to the number of shoots
per unit area, affecting the lawn's appearance and durability.
21. Q: What is recuperative potential in turfgrass? A: The ability of
turfgrass to recover from damage through new growth and spread.
22. Q: Which turfgrass has the best drought tolerance? A: Tall fescue and
Buffalo grass are among the most drought-tolerant turfgrasses.
23. Q: What is shade tolerance in turfgrass? A: The ability of turfgrass to
maintain acceptable quality and density in reduced light conditions.
24. Q: Which cool-season grass has the best shade tolerance? A: Fine fescue
has the best shade tolerance among cool-season grasses.
25. Q: What is wear tolerance in turfgrass? A: The ability to withstand foot
traffic and mechanical stress without significant damage.
26. Q: Which warm-season grass has excellent wear tolerance? A:
Bermudagrass has excellent wear tolerance and recovery ability.
, 27. Q: What is cold hardiness in turfgrass? A: The ability to survive freezing
temperatures and cold weather conditions.
28. Q: What are tillers in grass plants? A: Tillers are shoots that develop
from the base of the plant, creating a bunch-type growth pattern.
29. Q: What is apical dominance in turfgrass? A: The suppression of lateral
bud growth by the terminal growing point, affecting tillering.
30. Q: What happens when you remove the apical meristem through
mowing? A: Lateral buds are stimulated to grow, increasing tillering and
density.
31. Q: What is vernalization in turfgrass? A: The requirement for cold
treatment to initiate flowering in some grass species.
32. Q: What are ligules in grass identification? A: Membranous or hairy
structures at the junction of leaf blade and sheath, used for species
identification.
33. Q: What are auricles in grass identification? A: Claw-like appendages at
the base of leaf blades, present in some grass species.
34. Q: What is the collar region of a grass leaf? A: The junction between the
leaf blade and leaf sheath, important for identification.
35. Q: What is a grass inflorescence? A: The flowering structure of grasses,
including panicles, spikes, and racemes.
36. Q: What are spikelets in grass flowers? A: Basic units of grass
inflorescences containing one or more florets.
37. Q: What is seed dormancy in turfgrass? A: A condition where viable
seeds fail to germinate immediately due to internal or external factors.
38. Q: What breaks seed dormancy in cool-season grasses? A: Cold
stratification, scarification, or chemical treatments can break dormancy.
39. Q: What is the difference between seeded and vegetative establishment?
A: Seeded establishment uses seeds, while vegetative uses sod, sprigs, plugs, or
stolons.
40. Q: What is genetic diversity in turfgrass? A: The variation in genetic
makeup within and between turfgrass varieties and species.
41. Q: What are endophytes in turfgrass? A: Beneficial fungi that live inside
grass plants and can provide pest resistance and stress tolerance.
