| Abstract/Contents: | "University of Kentucky scientists investigated how morphological characteristics of creeping bentgrass leaves may be related its ability to resist infection by Sclerotinia homoeocarpa, the causal organism for dollar spot. The study found: All bentgrasses surveyed (A. palustris Huds. var. stolonifera, A. canina L., A. tenuis Sibth., and A. idahoensis Nash.) were glaborous. Trichomes were not present on either adaxial or abaxial surfaces. Stomatal surveys indicated that adaxial surfaces contained approximately twice as many stomata as abaxial surfaces in fairway-height turf. Significant correlations of stomatal densities with dollar spot severity were non-existent in both adaxial and abaxial surveys. There appears to be no relationship between stomatal density and dollar spot severity in fairway height bentgrass turf. There were no significant correlations between measured cuticle thicknesses and dollar spot severity." |
