Aim: The basic aim of this thesis was to disentangle phosphorus status-dependent and -independent effects of arbuscular mycorrhizal fungi (AMF, Glomus hoi) on the components of plant growth: morphology and assimilation rates, in perennial ryegrass (Lolium perenne L.). Materials & Methods: In a first experiment, I assessed phosphorus response functions of leaf and plant morphological components ...

The benefits of AMF and GPRB of available N and P t o p o t a t o were examined in pot experime n t containing clay loam soil and fertilized with organic matter. Mycorrhizal colonization of potato plants was over whelmed by bacterial inoculation. Results indicated inoculation with GPRB s trains and AMF increased shoot, root and total dry weight of potato plants s ignifican t ly c ompared with s...

ziziphus spina-christi are distributed in arid and semi-arid regions of world. most of these areas are subjected to soil salinity. so, the aim of this study was to find out the effects of different nacl concentrations on z. spina-christi seedlings growth, in the presence of a number of single and dual amf inoculums, to provide some information about possible effects of amf under salinity condit...

this study was conducted to determine the effects of arbuscular mycorrhizal fungi (glomus mosseae and glomus intraradices) symbiosis on mineral uptake of two pistachio cultivars (pistacia vera cv. qazvini and pistacia vera cv. badami-riz-zarand) grown in the greenhouse under different drought stress levels. drought stress (ds) reduced the mycorrhizal colonization in both cultivars as well as nu...

Forty-one soil and root samples from the rhizosphere of some dominant plants of deserts of Semnan province (NE Iran) were collected and examined in this survey. No mycorrhizal symbiosis was found in 24% of the collected plants, while in 76% of them mycorrhizal symbiosis was detected as fungal structures in roots or AMF spores in soils. The highest degree of colonization (76%) was found near the...

Arbuscular mycorrhizal fungi (AMF) are crucial for plants growing on marginal soils, especially those with a very high dependence AMF; one of them is few roots, such as cassava. This study aimed to identify the AMF associated cassava in six locations Manokwari Regency, West Papua, Indonesia. The research was carried out using an observation method and purposive sampling at 6 locations. Soil sam...

Arbuscular mycorrhizal fungi (AMF) represent a monophyletic fungal lineage (Glomeromycota) that benefits terrestrial ecosystems worldwide by establishing an intimate association with the roots of most land plants: the mycorrhizal symbiosis. This relationship results in an improved acquisition of nutrients (e.g., phosphate and nitrates) from the soil by the plant partners and, in exchange, allow...

BACKGROUND Nanoparticles are produced and used worldwide and are released to the environment, e.g., into soil systems. Titanium dioxide (TiO2) nanoparticles (NPs), carbon nanotubes (CNTs) and cerium dioxide (CeO2) NPs are among the ten most produced NPs and it is therefore important to test, whether these NPs affect plants and symbiotic microorganisms that help plants to acquire nutrients. In t...

The effect of four different arbuscular mycorrhizal fungi (AMF) on the growth and lipid peroxidation, soluble sugar, proline contents, and antioxidant enzymes activities of Zea mays L. was studied in pot culture subjected to two temperature regimes. Maize plants were grown in pots filled with a mixture of sandy and black soil for 5 weeks, and then half of the plants were exposed to low temperat...
