25 _________

26 Sod-forming grasses with extensive _________: smooth bromegrass (Bromus inermis) Kentucky bluegrass (Poa pratensis) quackgrass (Agropyron repens) prairie cordgrass (Spartina pectinata) foxtail muhly (Muhlenbergia andina) Johnson grass (Sorghum halepense) redtop (Agrostis alba). Sod-forming grasses with short ____________ : tall fescue (Festuca arundinaceae) side-oats grama (Bouteloua curtipendula) big bluestem (Andropogon gerardii) Indiangrass (Sorghastrum nutans). Sod-forming A B

27 Sod-forming…. ________ ground AB

28 Sod-forming…con’t Sod-forming grasses with extensive __________: bermudagrass (Cynodon dactylon) bentgrasses (Agrostis spp.) buffalo grass (Buchloe dactyloides). C

29 Sod-forming…. continued _______ ground C

30 Bunch-forming Bunchgrasses - chiefly ________________________: perennial ryegrass (Lolium perenne) orchardgrass (Dactylis glomerata) little bluestem (Schizachyrium scoparium) broomsedge (Andropogon virginicus) Bunchgrasses - reproducing _____________________: timothy (Phleum pratense) tall oatgrass (Arrhenatherum elatius var. bulbosum). The adventitious buds of bunchgrasses are found on the basal nodes in crown tissue and produce new tillers which remain within the surrounding leaf sheath of the mother stem. Reproduce vegetatively from adventitious buds on corms--corms are thickened, bulbous internodes which form in crown tissue, serving as storage organs. D E
