Abstract/Contents:Genetic improvement of creeping bentgrass dehydration and supraoptimal temperature stress resistance would enhance its use in warmer areas of the transition zone. The objectives of these studies were to: 1) determine if increased shoot hydration was associated with creeping bentgrass survival in response to elevated soil temperatures; 2) determine the relationship in plant stress response between soil dehydration and elevated soil temperatures as measured by shoot hydration; 3) estimate the heritability of shoot hydration in creeping bentgrass. Shoot hydration was positively associated with increased survival of creeping bentgrass plants under soil temperature stress in these studies. Hydration was determined to be a highly heritable trait in this population of bentgrass. As one mechanism of stress resistance in creeping bentgrass, screening for shoot hydration could be integrated into a breeding program for improved plant performance.
