mycoflora of iranian maize harvested in the main production areas in 2000.maize is one of the most important cereals produced in, and imported into, iran. the incidences of seed-borne fungi were determined in iranian maize harvested in 2000 from four major production areas with different climatic conditions, namely fars, khuzestan, kermanshah and mazandaran provinces. this is the first study to compare the mycoflora of maize in the aforementioned areas. mycological analyses showed a predominance of fusarium species (38.5%), followed by aspergillus species (8.7%), rhiz ...200415487329
fumonisin production by fusarium species isolated from freshly harvested corn in iran.fifty-one strains of fusarium verticillioides and f. proliferatum isolated from corn collected from four different geographic areas in iran, namely fars, khuzestan, kermanshah and mazandaran (an endemic oesophageal cancer (oc) area) were evaluated for their ability to produce fumonisins b1 (fb1), b2 (fb2) and b3 (fb3) in corn culture. fumonisin levels were determined by high-performance liquid chromatography. all tested strains of f. verticillioides and f. proliferatumproduced fumonisins within ...200515750730
incidence of fusarium verticillioides and levels of fumonisins in corn from main production areas in iran.a total of 52 corn samples collected in 2000 from four main corn production provinces of iran (fars, kermanshah, khuzestan, and mazandaran) were analyzed for contamination with fusarium verticillioides and fumonisins (fb(1), fb(2), fb(3), and 3-epi-fb(3)). the mean incidence of f. verticillioides (percent of kernels infected) for these four areas was 26.7, 21.4, 24.9, and 59.0%, respectively. the incidence in mazandaran was significantly (p < 0.05) above that of the other areas. all samples from ...200616881726
isolation and identification of atrazine-degrading bacteria from corn field soil in fars province of this study several agricultural fields with a long history of atrazine application in fars province of iran have been explored for their potential of atrazine biodegradation. after several subculturing for a period of 300 days acclimation, leads to an enhancement of atrazine biodegradation rate. a successful enrichment culture with a high capability for atrazine degradation was obtained (88%). a combination of enrichment culture technique, in a basal salt medium containing atrazine and carbon ...200719069990
