in order to investigate the effect of mycorrhizal fungi and phosphorus fertilizer on concentration of leaf nutrients and photosynthetic pigments of bean (phaseolus vulgaris l.) in condition of irrigation with saline water, an experiment was conducted based on completely randomized design with three replications in greenhouse of bahonar university of kerman, iran during 2010. the studied factors...

We monitored the development of intraradical and extraradical mycelia of the arbuscular mycorrhizal (AM) fungi Scutellospora calospora and Glomus intraradices when colonizing Plantago lanceolata. The occurrence of arbuscules (branched hyphal structures) and vesicles (lipid storage organs) was compared with the amounts of signature fatty acids. The fatty acid 16:1omega5 was used as a signature f...

The presence of actinorhizas and arbuscular mycorrhizas may reduce plant stresses caused by adverse soil conditions. A greenhouse experiment was conducted using a sediment with a high pH, resulting from the disposal of waste originated at an acetylene and polyvinylchloride factory, in which Black alder (Alnus glutinosa) seedlings were inoculated either with Glomus intraradices BEG163 (originall...

Abundant data on the effect of flavonoids on spore germination, hyphal growth and root colonization by AMF are available. Moreover, the flavonoid pattern in mycorrhizal roots changes, thus flavonoids have been suggested as arbuscular mycorrhizal signalling compounds. In our work we studied the accumulation of flavonoids in roots of Medicago sativa i) after the exposure of uncolonized roots to s...

The interaction among Glomus intraradices, Meloidogyne incognita, and cantaloupe was studied at three soil phosphorus (P) levels in a greenhouse. All plants grew poorly in soil not amended with P, regardless of mycorrhizal or nematode status. In soil amended with 50 mug P /g soil, M. incognita suppressed the growth of nonmycorrhizal plants by 84%. In contrast, growth of mycorrhizal plants inocu...

The excessive use of agrochemicals in the field to increase production and counteract negative effects caused by biotic abiotic factors has led a deterioration soil fertility, plus an increment impacts on environment human health. Therefore, application beneficial microorganisms as bioinoculants is eco-friendly alternative agrochemicals. Plant growth-promoting bacteria fungi have been effective...

• Root carbon (C) partitioning in two host plant species colonized by one of three arbuscular mycorrhizal (AM) fungal species was investigated. • Split-root systems of barley ( Hordeum vulgare ) and sugar maple ( Acer saccharum ) were inoculated on one side with one of three AM fungi. Leaves were labelled with 14 CO 2 3 wk after inoculation. Plants were harvested 24 h later and the root systems...
