| Abstract/Contents: | "The use of plant diversity as a means to enhance a plant communitys resistance to pests has long been proposed as a pest management strategy. Recent studies have found that cultivar mixes of St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] can provide improved resistance to insect pests and weed invasion over cultivar monocultures. However, before this approach can be considered for implementation on a larger scale, the permanence of those mixtures needs to evaluated not only over time but also in different latitudes. In the present study, simple sequence repeat (SSR) markers were used to track the composition of a field trial planted as mixtures of two or four cultivars in Jackson Springs (NC), and Citra and Fort Lauderdale (FL) one and three years after establishment. The frequency of each cultivar within each mix was determined by sampling 10 spots per plot. Then, four to six leaves per spot were collected and pooled for DNA extraction. Six SSR primer pairs with unique patterns for each cultivar were used to genotype each sample. Fragment analysis was performed using an Applied Biosystems 3730xl capillary sequencer. Changes in cultivar frequency from the one and three years after establishment were used to assess competitive dynamics among cultivars and mixture stability over time. This information will help determine the value of using cultivar mixtures as an IPM strategy for enhancing the sustainability of turfgrass systems." |
