Twenty isolates of Trichoderma harzianum wereisolated from the rhizosphere of healthy pistachio plants from different localities of Kerman Province, Iran.Five isolates with high antagonistic activity in in vitro assays against Verticillium dahliae (the causal agent of pistachio wilt), were investigated for their effect on the defense enzymes, peroxidase (PO), phenyl alanine-ammonia lyase (PAL) ...
Twenty isolates of Bacillus species obtained from livestock manure composts and cotton-waste composts were tested for their antagonistic effects in vitro against three green mold pathogens of mushrooms (Trichoderma harzianum, T. koningii, and T. viridescens). However, there exists a possibility Bacillus species may have antagonistic effects against mushrooms themselves, and thus the same 20 iso...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...

having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
The selection of saprotrophic antagonist fungi strains the Trichoderma genus by indicators cellulolytic and antagonistic activity for promising destructors in composting solid cellulose-containing municipal waste to obtain organic fertilizer was carried out. High (64,89–68,98 %) established asperellum D-11 (the basis biological preparation Fungilex, L) sp. L-3 component microbiological inoculan...
abstract the present study was conducted to investigate the effectiveness of a rather newly developed method in language teaching that is the use of paragraph reading task and whole reading task and their effects on improving efl learner’s speaking ability. to fulfill the purpose of the study, first 90 participants studying their course at sa eedi high school in tehran were chosen by means of ...
saprophitic pseudomonas species are root-colonizing bacteria that can improve plant health. efficient exploitation of these bacteria in agriculture requires knowledge of traits that enhance ecological performance in the rhizosphere. some pseudomonas fluorescens strains present biocontrol properties, protecting the roots of some plant species against plant pathogens. these bacteria induce system...
trichoderma species are among important antagonists of plant pathogenic fungi. the main purpose of this study was to evaluate the biocontrol potential of native trichoderma spp. isolates from sugar beet fields against phytophthora drechsleri and p. cryptogea, the causal agents of phytophthora root rot of sugar beet. during 2007–08, 85 isolates of trichoderma spp. from sugar beet fields in eight...
