Abstract/Contents: | "Roughstalk bluegrass (Poa trivialis) is a weed species reported more frequently during the past decade by Oregon cool season grass seed growers. This species is often found in the fields with waterlogged soils, indicating tolerance to waterlogging may promote this species. The objective of this study was to identify the morphological or physiological traits of roughstalk bluegrass which might contribute to waterlogging tolerance. Roughstalk bluegrass and tall fescue (Festuca arundinacea), a cool season grass seed, were subjected to a waterlogging treatment in the greenhouse. At the end of the study (28 d), the dry aboveground biomass, turf quality, leaf number, plant height, leaf water soluble carbohydrate content, and chlorophyll content of both species were reduced by the waterlogging treatment compared to the control. But no differences were found between the species for these measures. However, the root length increased by 5% in waterlogging treated tall fescue, but was reduced by 41% in waterlogging treated roughstalk bluegrass. The root dry weight and root water soluble carbohydrate content were reduced by 43 and 31% by waterlogging in tall fescue and 12 and 10% in roughstalk bluegrass, respectively. The shorter but thicker roots may help roughstalk bluegrass obtain oxygen from the top layer of the soil thus avoiding waterlogging stress. The greater root water soluble carbohydrate reserves in roughstalk bluegrass may provide substrate to maintain energy generation during waterlogging." |
