,Question 1
Which cool-season turfgrass species is most commonly used for
high-quality golf course putting greens in Indiana?
A. Zoysiagrass
B. Creeping bentgrass
C. Bermudagrass
D. Tall fescue
Correct Answer: B. Creeping bentgrass
Rationale:
Creeping bentgrass tolerates very low mowing heights and produces the
dense, smooth surface required for putting greens. Zoysiagrass and
bermudagrass are warm-season grasses not well adapted to Indiana's climate,
and tall fescue is too coarse for putting green use.
Question 2
Kentucky bluegrass spreads primarily by which structure?
A. Stolons
B. Rhizomes
C. Tillers only
D. Seed dispersal only
Correct Answer: B. Rhizomes
Rationale:
Kentucky bluegrass is a rhizomatous species, meaning it spreads laterally by
underground stems (rhizomes), giving it excellent self-repair ability after
damage. Stolons are above-ground runners used by grasses like bentgrass
and zoysiagrass.
Question 3
Which of the following is a bunch-type (non-spreading) cool-season grass
commonly used in Indiana lawns and athletic fields?
A. Kentucky bluegrass
Page 2
, B. Creeping bentgrass
C. Perennial ryegrass
D. Zoysiagrass
Correct Answer: C. Perennial ryegrass
Rationale:
Perennial ryegrass is a bunch-type grass that establishes quickly from seed but
has limited lateral spread and lacks the self-repair capacity of rhizomatous or
stoloniferous species.
Question 4
Turf-type tall fescue is often selected for Indiana lawns primarily because
of its:
A. Fine leaf texture
B. Drought and heat tolerance
C. Rapid stolon spread
D. Intolerance to foot traffic
Correct Answer: B. Drought and heat tolerance
Rationale:
Tall fescue has a deep root system that gives it superior drought and heat
tolerance compared to Kentucky bluegrass, making it a popular
low-maintenance choice, though it has a coarser leaf texture and spreads
slowly by short rhizomes.
Question 5
The 'transition zone' refers to a geographic area where:
A. Only warm-season grasses can survive
B. Both cool- and warm-season grasses are marginally adapted
C. Turfgrass diseases cannot occur
D. Pesticide labels do not apply
Correct Answer: B. Both cool- and warm-season grasses are marginally
adapted
Rationale:
Page 3
, The transition zone, which includes parts of Indiana, is too hot in summer for
ideal cool-season grass performance and too cold in winter for reliable
warm-season grass survival, so turf managers must balance trade-offs between
species.
Question 6
Which growth habit describes zoysiagrass?
A. Bunch-type only
B. Stoloniferous and rhizomatous
C. Non-spreading
D. Rhizomatous only, never stoloniferous
Correct Answer: B. Stoloniferous and rhizomatous
Rationale:
Zoysiagrass spreads by both above-ground stolons and below-ground
rhizomes, giving it excellent recuperative ability, though it is slow to establish
and green up in spring.
Question 7
A turfgrass leaf blade with a distinct 'boat-shaped' tip is characteristic of
which species?
A. Tall fescue
B. Perennial ryegrass and Kentucky bluegrass
C. Zoysiagrass
D. Bermudagrass
Correct Answer: B. Perennial ryegrass and Kentucky bluegrass
Rationale:
Both perennial ryegrass and Kentucky bluegrass have boat-shaped
(prow-shaped) leaf tips, which is one of the key vegetative features used to
distinguish them from tall fescue, which has a more tapered tip.
Question 8
Which is the best time of year to seed cool-season turfgrasses in Indiana?
A. Mid-summer (July)
