Turfgrass |
Plants that forms a continuous ground covering, and lives with regular mowing and traffic |
|
|
Turf |
An interconnecting community of turfgrass |
|
|
Lawn |
Ground covered with turfgrass and is mowed routinely |
|
|
Major Uses of Turfgrass |
1.Ornamental 2.Recreational 3.Functional |
3 Uses |
|
Visual Quality of Grass |
1.Color 2.Density 3.Texture 4.Uniformity 5.Growth Habits 6.Smoothness |
6 Types |
|
Color |
-Measure of light reflected by turfgrass -useful indicator of general condition of turf |
|
|
Loss of Color |
1.Nutritional Deficiencies 2.Pest Problems 3.Excessive Water (flood) 4.Water Deficit 5.Environmental Stress |
5 Ways |
|
Density |
Increased shoot density |
|
|
Texture |
-Measure of width of leaf blades -Varies between species and cultivars |
|
|
Uniformity |
Estimate of the even appearance of the turf |
|
|
Lowers Uniformity |
1.Bare Areas 2.Weeds 3.Insect Damage 4.Disease |
4 ways |
|
Functional Quality |
1.Rigidly 2.Elasticity 3.Resiliency 4.Recuperated Potential 5.Verdure 6.Rooting 7.Grain 8.Yield |
8 impacts |
|
Rigidly |
Resistance of turfgrass leaves to compression |
|
|
Leads to Rigidity |
1.Water Content 2.Temperature 3.Plant Size 4.Shoot Density 5.Plant tissue chemical composition |
5 Ways |
|
Elasticity |
Tendency turfgrass has to spring back and return to its original orientation after being compressed |
"Rubberband" |
|
Impacts on Elasticity |
1.Mowing 2.Equipment 3.Foot Traffic 4.Frost |
4 ways |
|
Resiliency |
Capacity the turf has to absorb shock without destroying it's characteristics |
|
|
Characteristics of Resiliency |
1.Turf leaves and shoots 2.Thatch |
|
|
Recuperative Capacity |
Capacity turfgrass has to recover from damage and/or injury |
|
|
Impacts on Recuperative Capacity |
1.Traffic 2.Diseases 3.Insects 4.Severely Compacted Soil 5.Foot Traffic 6.Vehicular Traffic 7.Inadequate fertility or soil moisture 8.Excessive fertility or soil moisture 9.Unfavorable Temperatures 10.Insufficient light |
10 ways |
|
Verdure |
Quantity of leftover alive grass after mowed |
|
|
Impacts on Verdure |
1.Resiliency 2.Rigidity 3.Wear Resistance |
3 ways |
|
Rooting |
Amount of Root Growth present at any time during growth season |
|
|
Things to look for when Rooting |
1.Numerous Roots 2.White to Cream Color 3.Depth of Roots 4.Dark Tan - Brown = dying roots |
4 things |
|
Grain |
-The way turfgrass grows horizontally instead of vertically -The way grass lays after mowed |
|
|
Yield |
-Amount of dry matter collected from turf after mowing -Helps measure growth rate |
|
|
Growth Habit |
Type of shoot growth present for a particular turfgrass |
|
|
Types of Growth Habits |
1.Bunch-type 2.Rhizomatous (Rhizome) 3.Stoloniferous (Stolon) |
3 types |
|
Bunch-type |
-Spread primarily or exclusively by tillers -May form small isolated clumps -Non-uniform surface |
|
|
Rhizomatous |
-Rhizome - Spread by below ground shoots -Form uniform turfs -Aerial shoots are oriented in upright position |
|
|
Stolonifous |
-Stolon - Spread by above ground, lateral shoots -Form uniform turfs -Aerial shoots are in a horizontal position |
|
|
Smoothness |
-Surface Feature of turf that affects visual Quality and playability -Measured with speed-stamp meter |
|
|
Botanical Classification |
Plantae (plants) - Kingdom Embroyophyta (embryo plants) - Division Phanaerogama (seed plans) - Subdivision Angiospermae (seed enclosed in ovary) - Branch |
Kingdom, Division, Subdivision, Branch |
|
Angiosperms |
-Flowering plants -In contrast to gymnosperms such as pines and cedars (cones) |
|
|
Classes |
-Monocotyledon = monocots, grass like plants -Dicotyledon = dicots, broadleaf plants |
|
|

4 characteristics |
|
Adaptation of Turfgrasses |
-Close grazing of grasslands (close mowing) -Grasses with short internodes and prostate -Growth habit developed (lower dense grass) |
|
|
Native Grasses |
Grasses that originate and persistent in a specific region |
|
|
