Effect strains of Mycorrhiza on root characteristic and concentration of phosphate, iron and zinc in cumin (Cuminum cyminum L.)

Symbiosis between plants and mycorrhizal fungus are very important for agriculture system and natural resource. In soil whit, less fertility mineral matter absorbed by Mycorrhiza can lead to improvement in growth that results increase in mycorhizal plant resistance in comparison whit non-mycorrhizal plants in stress condition. In order to test the influence of the strains of Mycorrhiza on root characteristic and nutriments on Cuminum cyminum L. an experiment was conducted based on completed design with three replications in western of Iran in 2009–2010 growing season. Strains of mycorrhiza including of Glomus fasciculatum, Glomus etanicatum, Glomus mosseae and Glomus intraradices. In these research traits as: root length, root length, root length/root dry weight ratio, total dry weight of colonization and concentration of phosphate, iron and zinc. Results of variance of analysis showed that strains of mycorrhiza had significant effected on studies characteristic, as Glomus fasciculatum had the highest root colonization, root dry weight, root length/root dry weight ratio. Strains of Mycorrhiza had significant affect on absorption of nutriments. Glomus fasciculatum had a more ability in absorption of phosphate, iron and zinc other then strains of mycorrhiza.
