creeping and colonial bentgrasses
, and creeping vs.
Copper spot is primarily a problem on bentgrasses
, especially velvet bentgrass.
The experiment consisted of 16 treatments (11 annual bluegrasses, four bentgrasses
, and one unplanted root zone control) and four replicates arranged as a randomized complete-block design.
. Turf performance under varying levels of deficit irrigation was evaluated by measuring turf quality, canopy spectral characteristics, and canopy photosynthetic rates.
Laser flow cytometry reliably classified fine rescue species (Festuca spp.) on the basis of chromosome number (Huff and Palazzo, 1998) and successfully determined the ploidy level of bentgrasses
(Bonos et al., 2002).
Although dollar spot resistant bentgrasses
tended to have fewer trichomes than susceptible clones, this was only found to be significant for the lower location.
Morphologically, creeping bentgrasses
are difficult to distinguish and taxonomic confusion has resulted in many synonymous names for the tetraploid species.
Among creeping bentgrasses
, the newer, denser cultivar L-93 had significantly higher ball lie than 'Penncross', a less dense, older cultivar.
Enhanced establishment of bentgrasses
by arbuscular mycorrhizal fungi.
The trial contained Emanuel Francis velvet bentgrass and several creeping bentgrasses
(Agrostis palustris Huds.).
Selective amplifications for bentgrasses
were made using different primer combinations from the final products of EcoRI/MseI digestion, adaptor ligation, and pre-amplification.
Breeding and selection for rhizomatous colonial bentgrasses
, Agrostis tenuis Sibth.
The results obtained in this study may prove helpful in the development of future guidelines for the establishment of isolation distances for seed production fields to reduce the potential for gene flow to or from both conventional and transgenic creeping bentgrasses
David Kopec from Arizona State University are recognized for the collection and donation of creeping bentgrasses
from Illinois and Arizona, respectively.
Original populations of bentgrasses
used to plant many golf courses in temperate North America were derived from highly heterogeneous populations of South German bentgrass mixtures.
