Representatives of fluorescent pseudomonad strains were assessed for their antagonistic activity against the blackleg of potato pathogen, Pectobacterium carotovorum subsp. atrosepticum. Tested strains belonged mainly to Pseudomonas fluorescens Biovars III, IV and V and they could produce inhibition zone on PDA medium against P. c. subsp. atrosepticum ranging from 1.5-5.5cm. Six selected strains...

abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
fusarium root and foot rot of wheat is caused by the fungus gibberella zeae (fusarium graminearum). this disease causes significant yield loss under infested soil and favourable condition. the aim of this study was to evaluate the efficacy of selected fungus strains against the wheat soil-borne pathogen f. graminearum under greenhouse and field conditions. the most potent isolates were 3 isolat...
phytoremediation is a biological method by which plants are used to remove environmental pollution caused by toxic elements such as the accumulation of cadmium, copper, lead, chromium, etc. from soil. the arbuscular mycorrhizal fungi (amf) help the plant to increase uptake and translocation of low mobility nutrients and also micronutrients. in this research, arbuscular mycorrhizal inoculant was...
fusarium wilt of chickpea, caused by fusarium oxysporum f. sp. ciceris, is one of the most important diseases of this plant in iran. in order to control this disease biologically, fluorescent pseudomonas were isolated from the rhizosphere of chickpea plants and enumerated using king’s medium b (kb). antifungal activity of 80 bacterial isolates against fusarium oxysporum f. sp. ciceris was evalu...
