| Abstract/Contents: | "Creeping bentgrass Agrostis stolonifera[ ]and colonial bentgrass A. capillaris[ ]are cool-season turfgrass species well adapted for utilization on golf courses. Natural stands of creeping bentgrass are often found in wetland areas and exhibit very poor tolerance to dry soils. Colonial bentgrass is frequently found in dryer habitats and has the ability to go dormant and recover quickly under water deficit stress. Hybridization between creeping and colonial bentgrass is possible and a better understanding of gene regulation under water deficit conditions could allow bentgrasses with improved water deficit stress tolerance to be developed. A greenhouse dry-down study was conducted using two creeping bentgrass clones with differing water use profiles and one colonial bentgrass clone. Three replicates of each genotype were treated, and well-watered control clones included for a total of 18 experimental units. Gravimetric Evapotranspiration (ET) was determined daily during the dry-down with control plants watered at 80% ET and deficit irrigation plants watered at 50% ET. Electrolyte leakage was monitored at the beginning and end of the dry-down with no differences detected. ET rates were very similar among all plants with the creeping genotypes exhibiting stress earlier and recovering more slowly than the colonial genotype. At the conclusion of the experiment all above ground plant material was harvested and RNA-seq analysis is being conducted." |
