  22. Sod-forming • Sod-forming grasses with ________________: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 _____________:tall fescue (Festuca arundinaceae) side-oats grama (Bouteloua curtipendula) big bluestem (Andropogon gerardii) Indiangrass (Sorghastrum nutans).

  24. Bunch-forming • Bunchgrasses - chiefly _____________branching:perennial ryegrass (Lolium perenne) orchardgrass (Dactylis glomerata) little bluestem (Schizachyrium scoparium) broomsedge (Andropogonvirginicus) • Bunchgrasses - reproducing _____________ via corms: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.
