this study was performed for evaluation of the qualitative traits of safflower (carthamus tinctorius l.) as affected by azotobacter and mycorrhizal symbiosis (host plant root symbiosis with the glomus fungi) as factorial experiment based on randomized complete block design with three replications in research farm of college of arak islamic azad university during growing season of 2011-2012. tre...

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...

Red clover, known for its estrogenic activity due to its isoflavones content (biochanin A, genistein, daidzein and formononetin), was inoculated with the arbuscular mycorrhizal fungus Glomus mosseae. Once the symbiotic fungus was well established, plants were harvested and we determined the root and shoot dry weight as well as the P-content. In roots and leaves the levels of biochanin A, genist...

The aim of this work was to evaluate the inoculation effect of two new endophytic diazotrophic bacteria and the interaction between arbuscular mycorrhizal fungi (AMF) and these bacteria on wheat plants. The experiment was carried out in a greenhouse with the two strains of diazotrophic bacteria, IAC11HT (Achromobacter insolitus) and IAC12HT (Zoogloea ramigera), and two AMF (Glomus sp. and Acaul...

Some plants can tolerate and even detoxify soils contaminated with heavy metals. This detoxification ability may depend on what chemical forms of metals are taken up by plants and how the plants distribute the toxins in their tissues. This, in turn, may have an important impact on phytoremediation. We investigated the impact of arbuscular mycorrhizal (AM) fungus, Glomus intraradices, on the sub...

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...

The potential of interactions between saprophytic and arbuscular mycorrhizal (AM) fungi to improve Eucalyptus globulus grown in soil contaminated with Zn were investigated. The presence of 100 mg kg 1 Zn decreased the shoot and root dry weight of E. globulus colonized with Glomus deserticola less than in plants not colonized with AM. Zn also decreased the extent of root length colonization by A...

introduction: drought stress is one of the main problems in agricultural productions in arid and semiarid regions such as iran. lack of water influences on most of plant physiological processes such as photosynthes, cellular development and uptake and transmission of nutrients in plants. some approaches such as selection of resistance cultivars to drought stress, and selection of dripped irriga...
