Allelopathic Potential of Various Plant Species on Downy Brome: Implications for Weed Control in Wheat Production
Allelopathy, the ability of plants to inhibit germination of other plants, is an untapped resource for weed control in crops that could revolutionize organic crop production. The main objective of the study was to evaluate allelopathic potential of various plant species on downy brome (Bromus tectorum L.), a major pest of wheat (Triticum aestivum L.). To screen for potential allelopathy, plants...
متن کاملEstimating carbon emissions from African wildfires
We developed a technique for studying seasonal and interannual variation in pyrogenic carbon emissions from Africa using a modelling approach that scales burned area estimates from L3JRC, a map recently generated from remote sensing of burn scars instead of active fires. Carbon fluxes were calculated by the novel fire model SPITFIRE embedded within the dynamic vegetation model framework LPJGUES...
متن کاملHost range of a deleterious rhizobacterium for biological control of downy brome
Bradley N. Johnson Tami L. Stubbs Land Management and Water Conservation Research Unit, USDA Agricultural Research Service, 215 Johnson Hall, Washington State University, Pullman, WA, 99164-6421 Pseudomonas fluorescens strain D7 (P. f. D7; NRRL B-18293) is a root-colonizing bacterium that inhibits downy brome (Bromus tectorum L. BROTE) growth. Before commercialization as a biological control ag...
متن کاملAn assessment of environmental conditions for control of downy brome by Pseudomonas fluorescens D7
Purpose: We evaluated the conditions that favoured Pseudomonas fluorescens strain D7 (P.f. D7) growth and inhibition of downy brome. Design/methodology/approach: Tn5 mutagenesis and a competitive assay were used to isolate mutants of P.f. D7. Isolates were screened for polysaccharide production and toxin response. Seven mutants were tested under varying pH, temperature and water potential and c...
متن کاملThe ghost of outcrossing past in downy brome, an inbreeding annual grass.
We investigated the frequency of outcrossing in downy brome (Bromus tectorum L.), a cleistogamous weedy annual grass, in both common garden and wild populations, using microsatellite and single nucleotide polymorphic (SNP) markers. In the common garden study, 25 lines with strongly contrasting genotypes were planted in close proximity. We fingerprinted 10 seed progeny from 8 individuals of each...
