black stem is one of the most important fungal diseases of sunflower which is caused by phoma macdonaldii. this research was conducted to clarify the interactions between a few breeder lines and wild-type accessions of sunflower with seven isolates of phoma macdonaldii, the causal agent, under controlled conditions. the experiment was carried out in randomized complete block design with three r...
to identify the high yielding lines with optimal characteristics, 40 recombinant inbred lines derived from a cross between ‘norstar’ (winter wheat) and ‘zagros’ (spring wheat) cultivars were examined using a randomized complete block design with three replications in 2014 at the research station of faculty of agriculture, university of tabriz, iran. the measured characters consisted of peduncle...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
introduction during the last decades interest in organic production of seed specially for medicinal plants take into consideration because of higher quality of organic products (hermes, 2010). seed germination is one of the principal stages in the plant life cycle and seeds with higher quality and vigour resulted in more pronounced seedlings growth and development. therefore, investigation of a...
