Percent total nonstructural carbohydrate (TNC) was measured in rhizomes plus roots of pinegrass (Calamagrostis rubescens Buckl.). The influence of connecting rhizomes on % TNC was evaluated by comparing results from sods with severed rhizomes to results from sods with intact rhizome connections. Severing rhizomes had no effect on % TNC of rhizomes plus roots of nonclipped sods. However, for clipped sods, % TNC was lower if rhizomes had been severed. Presumably, when rhizome connections are left intact, surrounding nonclipped tillers translocate carbohydrates to rhizomes plus roots of clipped tillers within a sod. This result has important implications in the grazing resistance of pinegrass. Since grazing typically involves an uneven utilization of a grass stand, the ungrazed or lightly grazed tillers should play an important role in maintaining the overall vigor of a pinegrass stand.
