seed dormancy has a critical role in ecological adaptation of wild plant species such as hordeum spontaneum, a wild relative of barley. in this study, 192 ecotypes of hordeum spontaneum maintained in national plant gene bank of iran (npgbi) originating from different climatic zones of the country were evaluated. morphological, phenological and physiological traits were recorded in the field. af...

Breeding of grain crops for phytoimmunity in the FSBSU FASC Northeast is carried out conditions natural and artificial epiphytotics. Every year, more than 1000 samples winter rye, spring soft wheat, barley oats their own breeding from VIR collection are studied. In studies conducted on snow mold, root rot, powdery mildew, brown stem rust, septoria blight, fusarium head ergot; wheat – loose smut...

Diversity within a crop of self-pollinating species can provide advantages in sustainable farming, including the ability to adapt environments. However, few results proving benefits various and climatic conditions are available. Our aim was find differences between heterogeneous homogeneous materials determine if crossing has advantage over mixing. We compared essential traits twelve spring bar...

The binding of asymmetrical and optically pure tridentate ligands (L = 1(S) and 1(R)) containing one carboxylic group and 2-naphthyl as an antenna to lanthanide ions (M = La(iii) and Eu(iii)) was studied in CH3CN, showing the successive formation of M:L, M:L2 and M:L3 stoichiometric species in solution. The europium complexes EuL3 were also synthesised, structurally characterised and their phot...

Sooty blotch and flyspeck (SBFS), a disease caused by a complex of fungi, results in substantial economic losses for commercial growers of sweet persimmon (Diospyros kaki L.) in Korea. However, many species causing SBFS in Korea have not been identified and sources of inoculum are uncertain. Based on mycological characteristics, pathogenicity, and molecular data, the causal fungi were identifie...

The most common bacterial diseases of mushrooms are the brown blotch caused by Pseudomonas tolaasii and ginger ‘gingeri’. Protection against infections consists in ensuring an appropriate microclimate cultivation rooms. aim study was to assess severity symptoms depending on amount irrigating water mushroom cultivation. crop infected with a suspension cells as equivalent application 2.6 × 107 10...

The acidic exopolysaccharides (EPSs) from 63 strains of mushroom production-associated fluorescent pseudomonads which were mucoid on Pseudomonas agar F medium (PAF) were isolated, partially purified, and characterized. The strains were originally isolated from discolored lesion which developed postharvest on mushroom (Agaricus bisporus) caps or from commercial lots of mushroom casing medium. An...

Ringspot symptoms in European mountain ash (Sorbus aucuparia L.), fig mosaic, rose rosette, raspberry leaf blotch, pigeonpea sterility mosaic (Cajanus cajan) and High Plains disease of maize and wheat were found to be associated with viruses that share several characteristics. They all have single-stranded multipartite RNA genomes of negative orientation. In some cases, double membrane-bound vi...

Two new species of the gobiid genus Cabillus, C. nigromarginatus sp. nov. and Cabillus nigrostigmus sp. nov. are described. Cabillus nigromarginatus (from Rodrigues, Western Indian Ocean) is distinguished from congeners by having 18-20 pectoral-fin rays; predorsal area naked; two scales with enlarged ctenii ventrally and dorsally at the caudal-fin base; head with anterior and posterior oculosca...
