به منظور شناسایی فلور قارچی ریشه و طوقه گندم در استان زنجان، در طی سال زارعی 90-1389 از 58 مزرعه گندم کشت دیم و آبی استان زنجان نمونه برداری به عمل آمد که ارقام سرداری، آذر2، امید و الوند از جمله ارقام رایج کشت شده در این مزارع بودند. جهت جداسازی قارچ های آلوده کننده غیر سطحی (داخلی) قطعاتی از ریشه و طوقه ضدعفونی شده بوسیله هیپوکلریت سدیم 1-5/0 درصد روی محیط کشت های آگار دار قرار داده شدند و بر...

striga hermonthica is a parasitic weed which largely constrains maize and sorghum production in western kenya. the weed mostly invades small scale farms and depending on severity, it may cause damage ranging from 10% to complete crop failure thereby aggravating the food insecurity in that region. this study aimed at evaluating fungal isolates as possible biocontrol agents against the weed. fung...

During the meteorologically contrasting period of 2003-2005, the contamination of winter wheat, malt barley and fodder barley grain with micromycetes during grain harvesting and preparation for storage was investigated. Micromycetes of over 70 species ascribed to 16 genera were isolated and identified, the density of their populations in grain was determined. Micromycetes with a population dens...

A total of 34 species belonging to 21 genera of fungi were recorded on passion fruits of both pure and hybrid origin in Uganda, however, the pure type exhibited wider spectrum (28 species and 16 genera) than the hybrid type (21 & 15). Also, yeasts (unidentified and Rhodotorula mucilaginosa) were also encountered in high numbers. Moreover, the mean count of all mycobiota obtained from the pure t...

Because tillage promotes the germination of many weed species and freshly killed plant material favours the growth of microbial pathogens, we hypothesised that the incorporation of green crop residue should temporarily reduce weed seedling emergence relative to unamended soil. Soil with field-incorporated green crop residue was compared with non-amended soil in glasshouse experiments by sowing ...

Background and Purpose Keratinophilic fungi are among the important groups of fungi living in the soil. This study aimed to isolate and identify keratinophilic fungi from the soil of three Iranian islands, namely Greater Tunb, Abu Musa, and Sirri, located in the Persian Gulf using morphological and molecular (polymerase chain reaction) methods. Materials and Methods In this study, a total of ...
