take-all disease of wheat (gaeumannomyces graminis var. tritici) (ggt) is one of the most destructive root diseases in the world. it has not been introduced resistant genotype against this disease. in this study, 416 genotype of bread wheat, received from different location of iran and other countries, were evaluated to take-all (t-41 isolate) in greenhouse conditions. root dry weight, shoot dr...

An experiment was conducted to investigate the effects of zinc application and salinity stress (0, 33, 66 and 99 mM NaCl) on some morphological and physiological parameters of soybean (Glycine max L., var. Williams). Results showed that zinc application improved shoot length, root fresh and dry weight and shoot fresh and dry weight under all salinity treatments. The catalase (CAT), ascorbate pe...

in order to the study of the salinity effects on seed germination and effecting parameter of fennel (foeniculum vulgare) was conducted a factorial experiment in a completely randomized design with two factors and three replications. factor a was 10 ecotypes, including; sardasht, saghghez, kerman, tabriz,sabzevar, rome, khusf, bojnoord, mashhad and shabestar and factor b was five concentrations ...

In order to investigate the effect of drought and salinity stress on caper plant (Capparis spinosa), a factorial experiment including two factors consisting of drought and salinity levels based on randomized complete block design (RCBD) with five blocks were carried out at College of Agriculture, Shiraz University, Shiraz, Iran. After pretreatment, seeds were germinated in petri dishes and then...

in the present study, the effect of two species of amf, glomus mosseae and glomus intraradices, alone and in combination, was evaluated on the growth criteria, chlorophyll content, and root rot disease caused by fusarium solani f. sp. pisi, on chickpea (cicer arietinum l.) under greenhouse conditions. chickpea seeds were sown into pots containing 100 g of amf inoculum (more than 1,000 propagule...

drought, high and low tempratures are the most important abiotic stresses in chickpea cultivation. improving plant root characteristics (root length and root volume) is one of the ways to increase drought tolerance in chickpea. mycorrhizal symbiosis increases drought resistance of host plants through different mechanisms. to study the effects of water stress and mycorrhizal fungi inoculation on...

in order to evaluate the effects of beneficial free living bacteria (azotobacter chroococcum and azospirillum brasilense) compared to different nitrogen fertilizer levels on yield and yield components of barley (hordeum vulgare cv reyhan) a field experiment was conducted at research station college of agriculture, ferdowsi university of mashhad in 2007-2008. the experiment was arranged in a ran...
