A Predictive Model for Soil Seed Bank Outcomes in the Pyrenophora semeniperda–Bromus tectorum Pathosystem
Allen P.S., Meyer S.E., Beckstead J. (2013): A predictive model for soil seed bank outcomes in the Pyrenophora semeniperda–Bromus tectorum pathosystem. Plant Protect. Sci., 49 (Special Issue): S21–S24. Pyrenophora semeniperda is abundant in soil seed banks of Bromus tectorum, where it kills a fraction of seeds throughout the year. The pathogen engages in a race with host seeds for endosperm res...
متن کاملFactors Affecting Bromus tectorum Seed Bank Carryover in Western Utah
Cheatgrass (Bromus tectorum L.) is a winter annual weed that presents a serious obstacle to rangeland restoration in the Intermountain West. The objective of this study was to evaluate factors regulating the size and persistence of cheatgrass carryover seed banks on semiarid sites in western Utah. We prevented current-year seed production in each of four habitats, then tallied emerging seedling...
متن کاملExposure to Low Water Potentials and Seed Dormancy Favour the Fungus in the Pyrenophora semeniperda-Bromus tectorum Pathosystem
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...
متن کاملIdentification of the Infection Route of a Fusarium Seed Pathogen into Nondormant Bromus tectorum Seeds.
The genus Fusarium has a wide host range and causes many different forms of plant disease. These include seed rot and seedling blight diseases of cultivated plants. The diseases caused by Fusarium on wild plants are less well-known. In this study, we examined disease development caused by Fusarium sp. n on nondormant seeds of the important rangeland weed Bromus tectorum as part of broader studi...
متن کاملa study of seed dormancy and dormancy breaking factors during after-ripening period of barley genotypes (hordeum vulgare l.)
to study seed dormancy and the after-ripening period in barley genotypes (57 dutch genotypes and two iranian cultivars (gorgan and valfair)), an experiment of randomized complete block design (two replications) was conducted at the research farm of collage of agriculture and natural resources, university of tehran in 2004-2005. in the growing stage of zgs92, panicle was collected. the percentag...
