Nitrogen responses of tall fescue and ryegrass survivor populations from a rate-of-nitrogen experiment

Host Range Differences Between Populations of Puccinia graminis subsp. graminicola Obtained from Perennial Ryegrass and Tall Fescue

Cool-season grasses are intensively cultivated for seed production in western Oregon, where stem rust is the most damaging disease on several species, including perennial ryegrass (Lolium perenne), annual ryegrass (L. multiflorum), and tall fescue (Festuca arundinacea). Stem rust also occurs on seed crops of orchard grass (Dactylis glomerata) and red fescue (F. rubra) in the region. The causal ...

Effects of fescue type and sampling date on the nitrogen disappearance kinetics of autumn-stockpiled tall fescue.

Two tall fescue [Lolium arundinaceum (Schreb.) Darbysh] forages, one an experimental host plant/endophyte association containing a novel endophyte that produces low or nil concentrations of ergot alkaloids (HM4) and the other a typical association of Kentucky 31 tall fescue and the wild-type endophyte (Neotyphodium coenophialum; E+), were autumn-stockpiled following late-summer clipping and fer...

Growth and nitrogen content of sunflower as affected by the rate and form of nitrogen

Effects of nitrogen on mesophyll cell division and epidermal cell elongation in tall fescue leaf blades.

Leaf elongation rate (LER) in grasses is dependent on epidermal cell supply (number) and on rate and duration of epidermal cell elongation. Nitrogen (N) fertilization increases LER. Longitudinal sections from two genotypes of tall fescue (Festuca arundinacea Schreb.), which differ by 50% in LER, were used to quantify the effects of N on the components of epidermal cell elongation and on mesophy...

A Preliminary Experiment on Agrobacterium tumefaciens-Mediated Transformation of the P5CS1 GENE in Tall Fescue

Abiotic stress conditions can be imposed on plants through either poor water quality or adverse climate condition. These types of stress affect plant growth and development throughout their life cycle. Plants that are tolerant to drought are therefore valuable, and turf grasses have the potential to grow tolerant. Turf grasses provide ground cover and offer multiple benefits, from their aesthet...
