| Abstract/Contents: | "Poa pratensis L. is a very diverse species, with cultivars that vary widely in drought resistance. As new cultivars have been released, it has been difficult to predict how their drought resistance would compare with older cultivars. Rutgers University researchers, working in the humid climate of New Jersey, USA, have recently developed a Poa pratensis classification system based on visual observations of a range of performance charactericstics. The goal of our study was to determine if the Rutgers system could be used to predict dehydration avoidance of fifteen diverse Poa pratensis cultivars in the semi-arid climate of Colorado, USA. The fifteen cultivars consisted of two Bellevue types, three BVMG types, three Common types, three Mid-Atlantic types, and four Other types. Dehydration avoidance of the cultivars was evaluated during dry-down periods by visually rating turf quality and leaf-firing. Based on orthogonal contrasts, dehydration avoidance in Colorado ranked: Mid-Atlantic types > Bellevue types > BVMG types > Common types. In the New Jersey research, the same four groups ranked: Mid Atlantic types = Bellevue types> Common types > BVMG types. Differences in rankings between Colorado and Jew Jersey can be attributed to higher disease pressure in New Jersey, where the Mid-Atlantic types had a high incidence of leaf spot (Bipolaris sorokiniana (Sacc,) Shoemaker) disease, and BVMG types had a high incidence of stripe smut (Ustilago striiformis (Westend.) Niessl) disease." |
