Identification of mycorrhizal fungi in the rhizospher of Thymus daenensis and mycorrhization of this species with Glomus intraradices in green house conditions

Mycorrhizal fungi are essential element of farming systems and play an important role in improving the growth of plants. In this research, first, fungi were recognized mycorrhizal fungi in rhizosphere of Thymus daenensis in Tehran and Eyvan areas. In total, was seen nine species of this fungi that were belong to Glomus and Scutellospora genuses. In second, for the studing the effect of Gloums intraradices on shoot height, fresh and dry weight, nitrogen and polyamines content, inoculum containing spores and colonized roots with this fungi was introduces to plants that were grown in green house conditions. The percent of root length colonization was 47.71. No significant difference between control and treatment shoot dry weight and stem height were detected. But in terms of shoot fresh weight and nitrogen levels, this difference was significant and conjugated putrecine in treamtments was decresed.
