Overall turfgrass quality characteristics may be divided into 2 groups. Identify the 2
groups:
visual and functional
utility and lawn
dynamic and non-dynamic
healthy and unhealthy
present or absent - Answer-visual and functional
Density is best defined as:
the distance between tillers
the amount of chlorophyll per unit area
the number of roots per unit of soil
,the number of leaves per unit area
the number of aerial shoots per unit area - Answer-the number of aerial shoots per unit
area
Texture is best defined as:
the width of the tiller
the width of the leaf blade
the softness of the leaf blade
the number of tillers divided by the surface area
the surface appearance of the leaf surface - Answer-the width of the leaf blade
Color is the most important turfgrass quality parameter and is universally agreed upon
that darker green color is best.
True
False - Answer-false
Uniformity is best defined as:
an estimate of the even appearance of a turf
the number of weeds growing in a turf
an estimate of the density times texture
the number of bare patches per unit area
none of the above - Answer-an estimate of the even appearance of a turf
Which of the following lists contain the different types of growth habit observed in
turfgrasses?
tillering and non-tillering
determinate and indeterminate
prostrate, upright, and decumbent

secular, non-secular, combination - Answer-rhizomatous, bunch-type, stoloniferous
Smoothness is best defined as follows:
a measure of the roughness of the leaf blade
the degree of taper of the leaf blade
a surface feature that affects visual quality and playability
a difficult to measure quality characteristic known as "softness"
the putting speed of a turf - Answer-a surface feature that affects visual quality and
playability
Which of the following terms do we use to describe texture?
, big vs small
