Transformed root cultures of three nonmycotrophic and one mycotrophic plant species stimulated germination and hyphal growth of the vesicular-arbuscular mycorrhizal fungus Glomus etunicatum (Becker & Gerd.) in a gel medium. However, only roots of the mycotrophic species (carrot) supported continued hyphal exploration after 3 to 4 weeks and promoted appressoria formation by G. etunicatum.

Nutrient composition and yield of soybean [Glycine max (L.) Merr] seeds are heritable traits affected by environmental factors. This study determined the effects of arbuscular-mycorrhizal (AM) fungi on seed protein, lipid, and phosphorus (P) composition and yield in soybean grown under a high nitrogen (N) regime. Plants were grown in pot cultures without AM fungi in P-fertilized (+P) or unferti...

Effect of constant and diurnally fluctuating temperatures on arbuscular mycorrhizal (AM) fungi [Glomus etunicatum (GE) and Gigaspora margarita (GM)] infection and the promotion of infected seedling growth through asparagus-AM fungus symbiosis were investigated. 1. At constant temperatures, spore germination rate became maximum at 25 •Ž in GE, and at 25•Ž and 30•Ž in GM. Hyphal growth was enhanc...

Arbuscular mycorrhizal fungi (AMF) are widely distributed in nature. They live in the roots of higher plants, in a symbiotic relationship. In this study, five commercial species of yams (Dioscorea spp.) were inoculated with six species of AMF, Glomus clarum, G. etunicatum, G. fasciculatum, Gigaspora sp., G. mosseae, and Acaulospora sp., in field cultivation conditions to investigate the influen...

to evaluate the effect of arbuscular mycorrhizal fungi under water deficit stress on linseed, a field experiment was conducted as split-plot in rcbd design with three replications at the research station of faculty of agriculture at shahrekord university in 2013. water deficit stress at four levels of no stress, mild, medium and severe stress as main factor and inoculation with glomus intraradi...

in this research the effects of mycorrhizal symbiosis and irrigation intervals on growth indices and grain yield of two sorghum cultivars was studied. field experiment was laid out as a split plot factorial based on randomized complete block design with three replications. irrigation intervals as main factor in three levels (7, 14 and 21days) and factorial combination of two sorghum cultivars (...

The production of inoculum is one of the hindrances in the large scale application of arbuscular mycorrhizal fungi (AMF). The objective of this work was to evaluate the effect of nutrient solutions with or without TrisHCl buffer, on sporulation of AMF. The experiment was carried out in a greenhouse, using a substrate with sand and vermiculite (1:1 v/v). Fifty spores of Gigaspora margarita, Scut...
