| Abstract/Contents: | "Creeping bentgrass (Agrostis stoloinfera) is a common grass that inhabits a myriad of environments, shows weedy characteristics, and hybridizes with other closely related species in the Agrostis genus. Moreover, the USDA is considering approval of an application to commercialize genetically-engineered herbicide-resistant (HR) creeping bentgrass. If approved, the likelihood of the transgenic trait entering feral Agrostis populations is high, and this could create environmental hazards such as increased pervasiveness, abundance, and/or spread into new habitats. The HR trait could also interfere with current weed management practices, removal of invasive plants with herbicides, and other stewardship practices. To explore the issue of stress tolerance and potential weediness, we have exposed four bentgrasses to two stresses: drought (three watering regimes) and salinity (0, 100, 200 or 400 mM NaCl). Plant biomass, photosynthesis, and water potential were measured over 28 days. Greenhouse experiments showed difference in stress tolerance between the four common, weedy, non-native Agrostis species (A. stolonifera, A. gigantea, A. capillaris, A. canina). Results showed that A. gigantea is the least sensitive to salinity and drought stress treatments. A. stolinifera showed some resistance to salt stress, while A. capillaris showed some resistance to drought stress. A. canina was the most sensitive to drought and salt treatments. This information is important because it fives and indication of how bentgrass populations with the HR trait could respond to the changing conditions in agricultural fields, roadsides, utility right-of-ways and other managed landscapes." |
