Effect of symbiosis of several mycorrhiza arbuscular fungi species on some quality ‎and physiological indices of potted lisianthus flower ‎(Eustoma grandiflorum ‘Matador Blue’)‎

This experiment established to investigate the effect of symbiosis of three mycorrhizal arbuscular fungi (Glomus intraradices,Glomus mosseae, Glomus howei) on growth and quality of dwarf lisianthus flower (Eustoma grandiflorum ‘Matador Blue’). The experiment carried out as factorial based on completely randomized design with three factors, mycorrhizal arbuscular fungi, concentration and bed culture in three replications. The results showed that mycorrhizal increased fresh and dry weight of aerial parts and roots, and plant height and number of buds. Chlorophyll concentration and nitrogen content also increased significantly with increasing mycorrhiza content compared to control. Generally, mycorrhiza application increased P and N content in pot lisianthus leaves. According to the results, incubation of medium with mycorrhiza significantly could improve the nutritional conditions of pot lisianthus and improve the vegetative and generative traits too.
