Apospory and parthenogenesis may be uncoupled in Poa pratensis: a cytological investigation
Sexual Plant Reproduction, 2001Despite the potential that apomixis has for agriculture, there is little information regarding the genetic control of its functional components. We carried out a cytohistological investigation on an F1 segregating population of Poa pratensis obtained from a cross between a sexual and an apomictic parent.

Gibberellins and the photoperiodic control of leaf growth in Poa pratensis
Physiologia Plantarum, 1997The role of gibberellins (GAs) in photoperiodic control of leaf elongation in Poa pratensis was studied by both application of exogenous GAs and analysis of endogenous GAs. Leaf elongation was strongly increased under long day (LD, 24 h) conditions at both 9 and 21°C, leaf length at 9°C LD being similar to that in plants grown in short days (SD, 8 h ...

Structure of the arabinoglucuronoxylan of Poa pratensis
Chemistry of Natural Compounds, 1974The xylan of the stems ofPoa pratensis belongs to the arabinoglucuronoxylans. It is constructed of D-xylopyranose residues connected to one another by 1 → 4 bonds. The branches contain residues of glucuronic acid and its 4-O-methyl ether, L-arabinose, and D-xylose.

Variation in Ecotypes of Poa pratensis
Botanical Gazette, 19461. Eight hundred progenies derived from single panicles of Poa pratensis collected in twenty-seven states of the United States were studied in the seasons 1941-1944 at Madison, Wisconsin. These included 541 Wisconsin collections. All were grown in spaced nursery rows. 2.

Dimorphic Panicle Formation in Poa pratensis
Botanical Gazette, 1951Plants of a single-panicle progeny of Kentucky bluegrass (Poa pratensis L.) were dimorphic in panicle formation, one level being produced terminally upon the plants and the second or lower level among the leaves. Second- generation progenies indicate that this is a genetic characteristic of this particular morphological type.

Plant Physiology and Biochemistry
Gibberellin (GAs) is an important plant hormone that plays a key role in plant growth and development. Gibberellin 2-oxidase (GA2ox) catalyzes the inactivation of biologically active GA or their direct precursors. In this study, five GA2ox genes were isolated from the wild type Poa pratensis 'Baron', named PpGA2ox3, PpGA2ox4, PpGA2ox5, PpGA2ox8, and ...

Effect of Snowmobile Traffic on Bluegrass (Poa pratensis)
Journal of Environmental Quality, 1976AbstractVarying snowmobile traffic was imposed on established bluegrass (Poa pratensis) areas at Arlington and Lancaster, Wisconsin for three winters. The effect on the stands, recovery, and vigor the following summer was monitored by close observations and the yield of frequent clippings.No reduction in bluegrass stands occurred following snowmobiling.
