To examine the effect of crop growth enhancer bacteria on quantitative and qualitative yield of safflower, an experiment in randomized complete block design was conducted in eight levels with four replications. Bacterial factor consisted of control (absence of bacteria), AzotobacterChroococcum,AzospirillumBrazilians, Pseudomonas Fluorescens, AzotobacterChroococcum+Azospirillum Brazilians, Azoto...

Changes in root organization and colonization could be relevant for wheat’s (Triticum durum Desf.) response to F. culmorum-induced crown rot disease (FCR). We investigated the biocontrol biostimulant efficiency of seeds coated with T. harzianum T-22 (T-22) four tetraploid wheat seedlings (ancient Saragolle Lucana modern Creso, Simeto, Ciclope). In an vitro experiment, repressed culmorum myceliu...

The peanut stunt virus (PSV) causes yield losses in soybean and reduced seed quality due to seed mottling. The objectives of this study were to determine the phenotypic reactions of soybean germplasms to inoculation with two PSV isolates (PSV-K, PSV-T), the inheritance of PSV resistance in soybean cultivars, and the locus of the PSV resistance gene. We investigated the PSV resistance of 132 soy...

Šafářová D., Brázda P., Navrátil M. (2014): Effect of artificial dsRNA on infection of pea plants by Pea seedborne mosaic virus. Czech J. Genet. Plant Breed., 50: 105–108. The effect of direct application of artificial dsRNA molecules derived from the viral coat protein gene and the possibility of RNA interference induction leading to protection against Pea seed borne mosaic virus (PSbMV) have ...

BACKGROUND AND PURPOSE Intensive agriculture is practised in Taiwan, and compost application is very popular as a means of improving the soil physical properties and supplying plant nutrition. We tested the potential of inoculation with thermotolerant microorganisms to shorten the maturity and improve the quality of biofertilizer prepared by composting. METHODS Thermotolerant microorganisms w...

Soybean (Glycine max (L.) Merrill) is one of the most important food crops for human and animal consumption, providing oil and protein at relatively low cost. The least expensive source of nitrogen for soybean is the biological fixation of atmospheric nitrogen by the symbiotic association with soil bacteria, belonging mainly to the genus Bradyrhizobium. This study was conducted to assess the ef...

New cultivars of sorghum are being developed for increased food use, as livestock feed, and for the bioenergy industry by manipulation of secondary metabolic pathways through breeding. Previous work has suggested that such modifications may have an impact on cultivar response to fungal pathogens. We investigated four inoculation strategies that may be used in studies involving pathogens of sorg...

in order to study on the effect of nitrogen, vermicompost and nitroxin biofertilizer on growth indices and phenology of sesame a field experiment was carried out at behbahan in summer of 2009. treatments were arranged in a factorial experiment based on rcbd with three replications. three rates of nitrogen fertilizer (50, 75 and 100% of region recommended nitrogen rate,) as a first factor, three...

Meloidogyne hapla-resistant plants grown from cuttings and inoculated with M. hapla larvae were free of galls. However, 35 to 48% of the seedling intercross progeny of resistant genotypes that were inoculated in the germinated seed stage were galled. There was an inverse relationship between the age of plants grown from seed and the percentage of plants galled by M. hapla; the older the plants ...

The aflatoxin-producing fungus Aspergillus flavus is a causal agent of preharvest contamination of food commodities such as oil seed crops worldwide. Peanut, corn and cottonseed are among the oil seeds that are susceptible to aflatoxin contamination during invasion of these crops by A. flavus. Contamination of agricultural commodities with aflatoxins can result in serious economic hardships to ...
