Stockpiling herbage can redistribute nutrient availability and supplement quantity for livestock, depending on production objectives. Brassicas (Brassica spp.) and improved prairiegrass (Bromus catharticus Vahl.) cultivars are adapted to growing conditions occurring in the Appalachian region and provide nutritionally valuable herbage in autumn; however, highly digestible brassica herbage may re...

Rhynchosporium consists of two species, R. secalis and R. orthosporum. Both are pathogens of grasses with R. secalis infecting a variety of Poaceae hosts and R. orthosporum infecting Dactylis glomerata. Phylogenetic analyses of multilocus DNA sequence data on R. secalis isolates originating from cultivated barley, rye, triticale and other grasses, including Agropyron spp., Bromus diandrus and H...

Finch H., Allen P., Meyer S. (2013): Exposure to low water potentials and seed dormancy favour the fungus in the Pyrenophora semeniperda–Bromus tectorum pathosystem. Plant Protect. Sci., 49 (Special Issue): S15–S20. In semi-arid regions of the United States, Pyrenophora semeniperda kills seeds of the winter annual Bromus tectorum. We report on pathosystem outcomes under manipulated water potent...

The nutritive value of manganese and its occurrence in animal and plant tissue has received considerable attention within the last few years. The literature relating to manganese in plant tissue has been reviewed by Lindow and Peterson (^)^, who reported analyses of 84 samples representing the principal classes of human foods. In a later paper by Skinner and Peterson {12), analyses of 54 feedin...

Plot-scale field studies were conducted to evaluate the efficacy of steam for the control of cropland weeds in comparison with common herbicides. Weed densities, biomass, or emergence after treatment were measured. Steam (3,200 kg/ha, energy dosage equivalent to 890 kJ/m2, speed of 0.8 m/s) and glyphosate (560 g ai/ha) gave similar control (. 90%) of seedling common lambsquarters and seedling r...

Background: Weedy non-native species have long been predicted to be more phenotypically plastic than native species. Question: Are weedy non-native species more plastic than natives? Organisms: Fourteen perennial plant species: Acer platanoides, Acer saccharum, Bromus inermis, Bromus latiglumis, Celastrus orbiculatus, Celastrus scandens, Elymus repens, Elymus trachycaulus, Plantago major, Plant...
