FACTORS AFFECTING THE VESICULAR-ARBUSCULAR INFECTION AND MYCORRHIZAL DEPENDENCY OF THIRTEEN WHEAT CULTIVARS

Variability in colonization of arbuscular mycorrhizal fungi and its effect on mycorrhizal dependency of improved and unimproved soybean cultivars.

Breeding selection of germplasm under fertilized conditions may reduce the frequency of genes that promote mycorrhizal associations. This study was developed to compare variability in mycorrhizal colonization and its effect on mycorrhizal dependency (MD) in improved soybean genotypes (I-1 and I-2) with differential tolerance to drought stress, and in unimproved soybean genotypes (UI-3 and UI-4)...

ARBUSCULAR MYCORRHIZAL FUNGI OF WHEAT FIELDS IN THE GOLESTAN PROVINCE

For identification of arbuscular mycorrhizal fungi (AMF), in the late springs of 2004 and 2005, wheat fields in the GolestanProvince (northeast of  Iran near the Caspian sea) surveyed and root cores sampled. After extraction of AMF spores and staining roots, 19 AMF identified as follow: Entrophospora infrequens, Glomus caledonium, G. clarum, G. constrictum, G. deserticola, G. eburneum, G. etuni...

Production of vesicular-arbuscular mycorrhizal fungus inoculum in aeroponic culture.

Bahia grass (Paspalum notatum) and industrial sweet potato (Ipomoea batatas) colonized by Glomus deserticola, G. etunicatum, and G. intraradices were grown in aeroponic cultures. After 12 to 14 weeks, all roots were colonized by the inoculated vesicular-arbuscular mycorrhizal fungi. Abundant vesicles and arbuscules formed in the roots, and profuse sporulation was detected intra-and extraradical...
