Abstract:: Kentucky bluegrass (Poa pratensis L.) cultivars are known to differ quantitatively in their photothermal floral inductive requirements. The extent to which these requirements are met influences the potential for subsequent panicle exsertion. A better understanding of the inductive requirements as they vary among cultivars would aid in the selection and...

Abstract:: Field studies were conducted to evaluate the effect of crop rotation on annual bluegrass plant population dynamics, seed rain, and seed bank in 1996 and 1997 at two sites. Growth-chamber studies were conducted to determine the influence of the mother plant environment on annual bluegrass germination. The change in population,...

Abstract:: Glasshouse and growth-chamber experiments were conducted to evaluate primisulfuron phytotoxicity and the influence of adjuvants on downy brome and Kentucky bluegrass. GR₅₀ (50% growth reduction) values were 0.97 ± 0.57 and 8.07 ± 1.85 g/ha for downy brome and Kentucky bluegrass, respectively. Primisulfuron was applied to downy brome and Kentucky...

Abstract:: Field experiments were conducted in 2002 and 2003 in the Willamette Valley of Oregon to investigate the effects of two plant growth regulators on the growth and reproduction of the weed annual bluegrass. Previous research suggested that the plant growth regulator prohexadione-calcium hastened senescence of annual bluegrass. Another plant growth...

Creator:: Tarasoff, Catherine
Abstract:: Weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia nuttalliana) infest Kentucky bluegrass seed fields of eastern Oregon. Weeping alkaligrass is an introduced species from Eurasia, whereas Nuttall’s alkaligrass is native to semi arid environments of western North America. These species are often referred to collectively as ‘alkaligrass’; however, for farmers...
