“…When comparing seed lots FSS >2.7 mm and FSS >2.7 mm + dis , seed disinfection increased grain yield by 300 kg ha -1 . This yield improvement is comparable with the results presented previously in other Nordic studies (Tahvonen et al 1995, Johnsson et al 1998). CCS and FSS >2.7 mm + dis attained a slightly lower grain protein concentration (%) as compared with other seed lots (Table 2).…”

Seed viability and vigour play important roles in seedling emergence, plant stand establishment and yield potential. The majority of cereal fields in Finland are typically sown with farm saved seed (FSS). If the quality of the seed is not known, there can be insidious yield reduction. This research was conducted to study the effects of seed quality on seedling emergence rate, seedling number and yielding capacity. The study comprised three-year field experiments conducted during 2007-2009, established at three sites: Jokioinen, Nousiainen and Ylistaro. Spring barley cultivars Saana (2007) and Annabell (2008)(2009) were sown at rate of 500 germinating seeds m -2 . Five seed lots were included as treatments: farm saved seed (FSS); downgraded seed <2.5 mm (FSS <2.5 mm ); upgraded seed >2.7 mm (FSS >2.7 mm ); upgraded seed >2.7 mm with disinfection (FSS >2.7 mm + dis ); and commercial certified seed with disinfection (CCS). Up-and down-graded seed lots (FSS <2.5 mm , FSS >2.7 mm , and FSS >2.7 mm + dis ) all originated from the FSS. Seedling emergence rate was measured from the time when coleoptiles started to break through the soil surface. The number of seedlings (3 × 1 m row per plot) was recorded at five-day intervals four times from the same rows. Plots were harvested at physiological maturity and grain yield (kg ha -1 ), hectolitre weight (HLW, kg) single grain weight (SGW, mg) and grain protein content (%) were recorded. Seed lots of CCS and FSS >2.7 mm + dis enhanced seedling emergence rate and increased the number of plants compared with other treatments. These two seed lots also produced the highest grain yield and had the lowest grain protein. Seed quality had an apparent effect on plant stand establishment and grain yield. A seed lot effect was evident despite identical targeted sowing rates that took into account germination rate and seed weight. Therefore, differences in seedling emergence and yielding capacity were likely outcomes of variation in seed vigour among the five treatments.

“…It is possible that the root exudates of carrot lack some characteristics necessary for the prolifération of S. griseoviridis. The efficacy of S. griseoviridis seed dressing on barley and spring wheat against foot rot disease was investigated by Tahvonen et al (1994) who demonstrated that wheat yields can be increased by seed dressirigs more efficiently than those of barley. Juhnke et al (1987) tested the rootcolonization ability of bacteria on wheat in fields and found that compared to other rhizobacteria, Streptomyces species were poor colonizers.…”

Les actinomycètes représentent une grande proportion de la biomasse microbienne du sol et ont la capacité de produire une large variété d’antibiotiques et d’enzymes extracellulaires. Plusieurs souches d’actinomycètes s’avèrent capables de protéger les plantes contre des maladies. Cette revue se penche sur le potentiel des actinomycètes comme (a) source de composés agronomiques, (b) agents stimulant la croissance des plantes et (c) agents de lutte biologique. La revue donne aussi des exemples de lutte biologique contre les agents phytopathogènes bactériens et fongiques par l’utilisation d’espèces d’actinomycetes déjà disponibles sur le marché ou qui le seront probablement au cours des prochaines années.Actinomycetes represent a high proportion of the soil microbial biomass and have the capacity to produce a wide variety of antibiotics and of extracellular enzymes. Several strains of actinomycetes have been found to protect plants against plant diseases. This review focuses on the potential of actinomycetes as (a) source of agroactive compounds, (b) plant growth promoting organisms, and (c) biocontrol tools of plant diseases. This review also addresses examples of biological control of fungal and bacterial plant pathogens by actinomycetes species which have already reached the market or are likely to be exploited commercially within the next few years

“…Evidence for production under more natural conditions was difficult to obtain, possibly due to problems associated with adsorption of the antibiotics to clays and the very small amounts likely to be produced in oligotrophic environments such as soil (43). Streptomycetes have been recommended for the biocontrol of fungal root and seed pathogens (15,37) but are better known as prolific producers of commercially important clinical antibiotics (22).…”

Actinomycetes were isolated from soybean rhizosphere soil collected at two field sites in Brazil. All the isolates were identified as Streptomyces species and were screened for streptomycin production and the presence of two genes, strA and strB1, known to be involved in streptomycin biosynthesis in Streptomyces griseus. Antibiotic resistance profiles were determined for 53 isolates from cultivated and uncultivated sites, and approximately half the strains were streptomycin resistant. Clustering by the unweighted pair group method with averages indicated the presence of two major clusters, with the majority of resistant strains from cultivated sites being placed in cluster 1. Only representatives from this cluster contained strA. Streptomycetes containing strA and strB1 were phenotypically diverse, and only half could be assigned to known species. Sequence comparison of 16S rRNA and trpBA (tryptophan synthetase) genes revealed that streptomycinproducing streptomycetes were phylogenetically diverse. It appeared that a population of streptomycetes had colonized the rhizosphere and that a proportion of these were capable of streptomycin production.
