Arbuscular mycorrhizal fungi (AMF) establish beneficial symbiotic associations with plants, enhancing their nutrient uptake, growth, and stress tolerance. The present study was aimed to investigate AMF spore density, species composition, colonization patterns, correlation of these indices soil physicochemical parameters at four vineyards located in one the most important grape-producing regions...

improved pasture establishment in plants, especially in arid and semi-arid is very important application of biological fertilizers in pasture can be considered as a useful approach. that is one of the sources of the symbiotic fungus.. the purpose of the present study was to investigate the possibility of enhancing seedling establishment and growth rate of bromus kopetdaghensis under natural hab...

the effects of arbuscular mycorrhizal (am) fungi on growth and phosphorus (p) inflow into two species of clover plant with different root morphology were studied. the experiment was arranged as a randomized complete block design consisting of a 2×3×3 factorial combination of two clover species (trifolium alexandrinum l. and trifolium pratense l.), three mycorrhiza states (without mycorrhiza, gl...

Attractions between like-charged polyelectrolytes have been observed in a variety of systems (W.M. Gelbart, R.F. Bruinsma, P.A. Pincus, V.A. Parsegian, Phys. Today 53, September issue, 38 (2000)). Recent biological examples include DNA, filamentous viruses, and F-actin. Theoretical investigations on idealized systems indicate that counterion correlations play a central role, but no experiments ...

Among closely related citrus genotypes growing in high phosphorus (P) orchard soils, there is a tendency for less mycorrhizal-dependent (M-dependent) species to have lower rates of root colonization than more M-dependent species. We hypothesized that the less M-dependent the citrus species the more limited is their carbohydrate (CHO) allocation to the M fungus. In a glasshouse study at low and ...

Bark beetles play an important role as agents of natural renovation and regeneration in coniferous forests. Several studies have documented the metabolic capacity of bacteria associated with the gut, body surface, and oral secretions of these insects; however, little is known about how the bacterial community structure changes during the life cycle of the beetles. This study represents the firs...

In order to study the effects of drought stress and mycorrhiza fungi on establishment rate and some growth-morphological traits ofZiziphora clinopodoides, pot experiments were conducted as factorial design based on a completely randomized design at the research greenhouse of agricultural faculty, Ferdowsi University of Mashhad in 2014; pots were combined as four levels of drought stress includi...

Arbuscular mycorrhizal fungi (AMF) and plant growth promoting rhizobacteria (PGPR) have been proposed as biofertilizers for sustainable agriculture. Nevertheless, many of the delivery approaches these beneficial microorganisms disadvantage limited applicability. The study aim was to evaluate fertilizing potential seed coating with microbial fertilizers on yield parameters maize sorghum. Field t...

influence of arbuscular mycorrhizal fungi (amf) (glomus etunicatum, g. intraradices and glomus versiforme) and external phosphorus supplement (8 and 35 mg p kg-1 soil) on leaf p, zn, cu and fe nutrition of 4-month-old tea(camellia sinensis) was studied in an glass house pot experiment. the highest leaf p concentration (up to 59.43% increase) was found in g. versiforme inoculated seedlings gro...
