Variability of Bluegrass (Poa) in Siberia
Siberian bluegrass (Poa) includes a number of polymorphic species such as P. arctica s.l., P. nemoralis s.l., P. palustris s.l., P. pratensis s.l., P. sibirica s.l., and P. smirnovii s.l., plus numerous hybrids and purported derivatives (e.g., P. attenuata s.l., P. glauca s.l., P. urssulensis s.l.). In Siberia Poa is represented by morphologically isolated species and hybrid-apomictic complexes...
متن کاملFall Armyworm (lepidoptera: Noctuidae) Resistance in Texas Bluegrass, Kentucky Bluegrass, and Their Hybrids ( Poa Spp.)
The fall armyworm Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is a destructive pest of many species of both C3 and C4 (cooland warm-season) turfgrass. No-choice experiments were conducted to evaluate 13 turfgrass genotypes of various Poa spp. for susceptibility or resistance to the fall armyworm. All 13 genotypes, including 8 Texas bluegrass ( Poa arachnifera Torr.), 2 Kentuck...
متن کاملThe Challenge of a Siberian Bluegrass (Poa) Phylogeny
In Siberia, the bluegrass genus (Poa) comprises 43 species and 61 subspecies in 12 sections. Diverse modes of speciation, including polyploidy and hybridization, have led to reticulate evolution and adaptive radiation. Cladistic methods that ignore hybridization and reticulate evolution may not be appropriate for morphological data. The number of morphological characters suitable for bluegrass ...
متن کاملInhibition of Drought Stress Using Folic Acid in Kentucky bluegrass (Poa pratensis L.) under in vitro culture
Considering the high water requirement of grass during growth stages and the limitation of irrigation sources, it is important to find a suitable way to reduce the water requirement of the lawns as cover plants used in the Landscape. The purpose of this study was to investigate the effect of 2,4,5-T on the induction of callus from the hypocotyl explant in Kentucky bluegrass, induce in vitro dro...
متن کاملControlling Annual Bluegrass (Poa annua L.) Summer Patch Disease with Faeriefungin
Faeriefungin, an antibiotic produced by the actinomycete Streptomyces griseus var. autotrophicus MSU-32058/ATCC 53668, was tested in field trials on golf course fairways to determine if it could control annual bluegrass (Poa annua L.) summer patch effectively. Test sites with a history of severe summer patch outbreaks caused by Magnaporthe poae Landschoot and Jackson were chosen for study. Faer...
