| Abstract/Contents: | "Bahiagrass (Paspalum notatum) has long been used in pastures, forages, and roadsides, but its ability to grow and reproduce in a wide range of environments has contributed to its success and spread as a turfgrass weed. Differences have been observed in bahiagrass seedhead morphology over the past decade and hybridization has been documented between several Paspalum spp. The existence and spread of bahiagrass hybrids may reduce the efficacy of current herbicidal controls and increase the magnitude of weed infestation in turfgrass systems. Therefore, the objective of this research was to identify hybrid bahiagrass biotypes and document their distribution throughout the state of Georgia. Twelve counties were selected throughout the state of Georgia to represent the various climatic differences. Hybrid bahiagrass biotypes were collected from roadsides over a 2 week period during the summer of 2012. Approximately 12 to 15 hybrid bahiagrass biotypes were obtained from 3 to 4 roadside locations within each county. Seedhead branch number was used to identify possible hybrid bahiagrass biotypes. Hybrid bahiagrass biotypes with seedhead branch numbers ranging from 3 to 8 were collected throughout the state. A non-hybridized bahiagrass biotype (V-shaped seedhead) was collected from each location for comparison purposes. Each hybrid bahiagrass biotype (above-ground biomass + rhizomes and roots) were excavated from each site and transplanted into 1 liter pots containing soil native to that location. Hybrid bahiagrass biotypes with 3 and 4 seedhead branches were collected from all 12 counties. Hybrid bahiagrass biotypes with 5 seedhead branches were collected in 9 counties, while biotypes with 6, 7, and 8 branches were collected from 6, 3, and 1 counties, respectively. The occurrence of 3- to 8-branched seedhead hybrid bahiagrass biotypes was visually correlated with the close proximity of dallisgrass (Paspalum dilatatum) and/or vaseygrass (Paspalum urvillei). Morphological and genetic differences are currently being determined for each collected biotype. Initial observations suggest that differences may exist with respect to plant height, leaf blade width, and rhizome morphology." |
