Question 1

Turfgrasses are among the oldest plants used for landscaping.

Accepted Answer

Turfgrasses have been used for landscaping, sports fields, and other purposes for centuries, making them among the oldest plants utilized for these purposes.

Question 2

Certain grasses possess greater resistance than others to insects and disease pests.

Accepted Answer

Different grass species and even varieties within a species can have varying levels of resistance to insects and disease pests due to genetic differences and adaptations.

Question 3

A pound of fine-textured grass seed contains considerably fewer seeds than the same weight of coarse-textured seed.

Accepted Answer

False

Question 4

Grass seed plants produce new leaves only in the spring.

Accepted Answer

Grass seed plants can produce new leaves throughout the growing season, not just in the spring. This growth pattern depends on the type of grass and environmental conditions.

Question 5

Warm season grasses do not flourish during spring and fall when temperatures fall below optimum.

Accepted Answer

Warm season grasses thrive in hot weather and typically struggle to grow vigorously during the cooler temperatures of spring and fall.

Question 6

Professional landscapers usually purchase grass seed retail.

Accepted Answer

Professional landscapers typically purchase grass seed in bulk or wholesale to save costs and ensure they have enough supply for large projects.

Question 7

Blends attempt to retain the advantages of both mixtures and single-species plantings that are included.

Accepted Answer

Blends combine different species or varieties to leverage the strengths and mitigate the weaknesses of each, aiming to achieve a balance of benefits found in both mixtures and single-species plantings.

Question 8

Single species turf plantings offer a more uniform appearance than mixtures.

Accepted Answer

Single species turf plantings provide a more uniform appearance because all the grass plants have the same growth habits, color, and texture, unlike mixtures which can result in a more varied appearance due to the different characteristics of the species included.

Question 9

Fine-textured grass seeds are more expensive than coarse-textured grass seeds.

Accepted Answer

Fine-textured grass seeds, such as those for Kentucky bluegrass or fine fescues, are often more expensive due to their higher quality, more delicate handling requirements, and sometimes slower growth rates, which can demand more careful cultivation and maintenance.

Question 10

Rhizome and stolon-producing grasses tend to reproduce slower than bunched-type grasses.

Accepted Answer

Rhizome and stolon-producing grasses often spread more quickly and efficiently than bunched-type grasses because they use their underground stems (rhizomes) or above-ground runners (stolons) to propagate and cover ground rapidly.

Question 11

What is the preferred daytime temperature (in degrees Fahrenheit) for warm season grasses?
A) 50 to 65
B) 65 to 78
C) 80 to 95
D) 95 to 105

Accepted Answer

Warm season grasses thrive best in temperatures between 80 to 95 degrees Fahrenheit, as they are adapted to hotter climates.

Question 12

The number of leaf shoots produced by a grass plant is a measure of what?
A) texture
B) color
C) thickness
D) density

Accepted Answer

The number of leaf shoots produced by a grass plant is a measure of its density. A higher number of leaf shoots indicates a denser, thicker grass coverage.

Question 13

What is the material in a bag of grass seed that adds bulk and weight but will not grow?
A) noxious weeds
B) filler
C) fertilizer
D) inert material

Accepted Answer

Inert material is added to bags of grass seed to add bulk and weight but does not have the capacity to grow. This material is non-reactive and serves as a filler without contributing to the germination or growth of the seeds.

Question 14

What daytime temperature (in degrees Fahrenheit) favors the growth of cool season grasses?
A) 40 to 55
B) 60 to 75
C) 50 to 60
D) 80 to 90

Accepted Answer

Cool season grasses thrive in temperatures between 60 to 75 degrees Fahrenheit, as this range provides optimal conditions for their growth and development.

Question 15

What characteristic of a grass is determined by the width of the grass leaf?
A) texture
B) size
C) length
D) thickness

Accepted Answer

The texture of a grass is determined by the width of the grass leaf. Narrower leaves typically result in a finer texture, while wider leaves lead to a coarser texture.

Question 16

What label must appear on the package of grass seed to give a breakdown of the contents of the seed packet?
A) specifications
B) examination
C) breakdown
D) analysis

Accepted Answer

The correct label that must appear on the package of grass seed to give a breakdown of the contents is "analysis." This provides detailed information about the seed mix, including types of grass seeds and their percentages, as well as other components.

Question 17

The presence of wheat in a grass seed mixture will be referred to as what type of seed?
A) crop
B) weed
C) noxious
D) wild

Accepted Answer

Wheat in a grass seed mixture is considered a crop seed because it is a type of plant that is intentionally grown for agricultural purposes, even though it may not be the desired plant in a specific grass seed mix.

Question 18

Some weed seeds are extremely undesirable and difficult to eradicate. What term is applied to identify them?
A) crop
B) noxious
C) invasive
D) None of these answers is correct

Accepted Answer

Noxious weeds are those classified by law as being especially undesirable, harmful, and difficult to control or eradicate.

Question 19

What type of grass is Bermudagrass?
A) warm
B) cool
C) transitional
D) None of these answers is correct

Accepted Answer

Bermudagrass is a warm-season grass, thriving in hot weather and going dormant in cooler temperatures.

Question 20

What type of grass is Kentucky bluegrass?
A) warm
B) cool
C) transitional
D) None of these answers is correct

Accepted Answer

Kentucky bluegrass is a cool-season grass, thriving in cooler temperatures and climates.
