معرفي پنج گونه گلوموس از قارچهاي ميكوريز آربوسكولار ايران

Five Glomus species of arbuscular mycorrhizal fungi from Iran

Glomus species are most common arbuscular mycorrhizal fungi symbiont with roots of field crops and fruit trees. These fungi improve water and nutrient elements absorption. therefore increase growth and yield of plants. In order to collecte and identify these fungi, roots and soils were collected from wheat, barley, corn, sorghum fields and few jujube orchards located in Khorasan, Semnan, Tehran and Khuzestan provinces. Glomus species symbiont with their roots were studied and identified in trap and pure pot cultures. Five Gloinu.s species were identified as follow: Glorious claraideum (in 11% of samples), G. clarum, G. dominikii* and G. coronatuni* (each in 1% of samples ) and G. elunicatu, (in 2% of samples). All of these fungi are new for mycoflora of these plants in Iran and two species, which remark with aristics, are new for mycorrhizal flora in Asia. Morphological characteristics, taxonomy, mycorrhizal associations and distribution of these species are illustrated.
