root colonization by antagonist bacteria has been considered as a prerequisite for a successful biocontrol. for an effective suppression of plant disease, an efficient and fast colonization is necessary to prevent the establishment of pathogen on the root system. colonization of canola root by strain utpf86 were investigated with and without rhizoctonia solani ag-4, under greenhouse conditions....

Common mycorrhizal network (CMN) allows nutrients and signals to pass between two or more plants. In this study, trifoliate orange (Poncirus trifoliata) and white clover (Trifolium repens) were planted in a two-compartmented rootbox, separated by a 37-μm nylon mesh and then inoculated with an arbuscular mycorrhizal fungus (AMF), Diversispora spurca. Inoculation with D. spurca resulted in format...

in the course of the present study, samples were taken from the non-defoliant strain of verticillium dahliae (ss-4) from infected olive groves in toshan area in southern gorgan. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and after identification was reaned on tomato seedlings cv. rutgers. during the study, one-year-old seedlings of olive cultivars zard...

to evaluate the effect of arbuscular mycorrhiza (glomus mosseae) under salt stress on physiological and some nutrient absorption in new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with three replications (three pots for each replication) in greenhouse in shahrekord university in 2014. treatments were inoculation of substrate with three levels of arb...

with the aim to examine lead tolerance of populus nigra (clone 62/154) in symbiosis with arbuscular mycorrhizal fungi, a greenhouse experiment was carried out in a factorial randomized complete scheme with two factors 1) fungal inoculation in 4 levels (control, inoculation with glomus mosseae, inoculation with g. intraradices and inoculation with g. mosseae + g. intraradices) and 2) lead in 4 l...

to evaluate the influence of arbuscular mycorrhizal inoculation on growth, yield and minituber production of potato plantlets, a pot experiment was conducted using a factorial based on completely randomized design with four replications. the factors were mycorrizal inoculation (non-inoculated and inoculated with glomus mosseae, glomus etunicatum and mixed of them) and two potato cultivars (agri...

the present study examined the effects of mycorrhizal fungus glomus sp. on pistachio growth parameters and root-rot disease of pistachio seedlings under greenhouse conditions. the experiment was conducted in factorial arrangement based on completely randomized design with six replications. examined factors included: levels of glomus inoculation (with (m1) and without inoculation (m0) and two le...

in this research the effect of two species of arbuscular mycorrhizal fungi, glomus mosseae and glomus intraradices on root knot nematode, meloidogyne javanica was investigated and in different treatments the effects of this interaction on parameters of plant growth , nematode infection and mycorrhizal development were evaluated.shoot fresh and dry weight significantly increased in mycorrhizal t...

This study proposed a rapid method to quantify the colonization rate of arbuscular mycorrhizal fungi (AMF) in plant roots. The method involved the use of an image analysis software (WinRHIZO Pro). The colonization rate is defined as the ratio of the fungal body to the plant root area in a micrograph. Three seedlings of Chengiopanax sciadophylloides, a woody species that accumulates radiocesium,...
