| Abstract | ||
| A field survey of three regions in Salah Al-din governorate Tikrit. Al-Dour and Baiji was conducted during February, March and April of the year 2010 to determine genera/species of Vesicular Arubscular Mycorrhiza(VAM) fungi and the percentage of mycorrhizal infection on wheat (Triticum aestivum) barley (Hordeum vulgare) and alfalfa( Medicago sp.), It was noticed that there was a difference in VAM infection ratio from site to site and from month to month , The highest VAM infection ratio 44.4% was recorded in alfalfa plants(as average of sites and monthes) whereas in barley and wheat was 43.3 and 34.5% , respectively.Tikrit region was superior on other regions, VAM infection percentage in Tikrit site was 48.9% compared to 42.2 and 31.1% in Al-Dour and Baiji regions, respectively.The results showed that the higher VAM infection percentage was 46.7% in April followed by 39 and 31.1% in March and February, respectively. G.mossea and G.pulvinatum in addition to four isolates related to Glomus genus including Glomus sp.1. Glomus sp.2. Glomus sp.3 and Glomus sp.4 and two isolates related to Entrophospora and Gigaspora were isolated from all regions surveyed. The results showed that Glomus genus was the most common in all of the studied regions. while Gigaspora sp. was the less common. The highest spore number (5.40 spores /10g soil) was for G.mossea from alfalfa plant. The results showed that the Tikrit region had given the highest spores count (6.7 spores /10g) compared to Al-Dour (3.98 spores /10g ) and Baiji (3.08 spores /10g) in all studied months. In April the highest spores count in all surveying study regions from all host plants was 8.25, 7.63 and 8.75 spores /10g of wheat, barley and alfalfa plants in Tikrit region, respectively. | ||
