La sustentabilidad de los ambientes agrícolas en la región pampeana húmeda argentina es afectada por el monocultivo soja (Glycine max (L.) Merr.). baja eficiencia uso recursos del ambiente durante barbechos y su efecto negativo sobre sostenibilidad productividad sistemas producción hace necesaria adopción prácticas tales como inclusión un cultivo cobertura (CC) invernal entre cultivos renta esti...

The phenanthrene-degrading activity (PDA) of Pseudomonas putida ATCC 17484 was repressed after incubation with plant root extracts of oat (Avena sativa), osage orange (Maclura pomifera), hybrid willow (Salix alba x matsudana), kou (Cordia subcordata) and milo (Thespesia populnea) and plant root exudates of oat (Avena sativa) and hybrid poplar (Populus deltoides x nigra DN34). Total organic carb...

AAC Oravena is a white-hulled spring oat (Avena sativa L.) cultivar selected and developed under organic management. yields well conventional production systems, compared with check cultivars. has good milling quality. was registered (Reg. No. 7561) by the Variety Registration Office, Canada Food Inspection Agency, on 3 July 2014.

Light-induced coleoptile stimulation and mesocotyl suppression in etiolated Avena sativa (cv. Lodi) has been quantitated. Etiolated seedlings showed the greatest response to light when they were illuminated 48 to 56 hours after imbibition. Two low-irradiance photoresponses for each tissue have been described. Red light was 10 times more effective than green and 1,000 times more effective than f...

Naturforsch. 44c, 12—18 (1989); received November 25, 1988 Microheterogeneity, Pest Sequence, Phytochrome Denaturation, Protein Conformation Phytochrome from etiolated oat seedlings (Avena sativa L.) was investigated by “native” gel electrophoresis and by isoelectric focusing. At pH 8 . 8 the Pfr form migrate...

The genus Avena comprises four distinct genomes organized in diploid (AA or CC), tetraploid (AABB or AACC) and hexaploid species (AACCDD), constituting an interesting model for phylogenetic analysis. The aim of this work was to characterize 45S rDNA intergenic spacer (IGS) variability in distinct species representative of Avena genome diversity-A. strigosa (AA), A. ventricosa (CvCv), A. erianth...
