This thesis is focused on mycorrhizal symbiosis in greengrocer production, shows general information about anatomy and distribution of mycorrhizal symbiosis. Summarized interesting scientific knowledge refers to the importance of the nutrient element, morphological changes and mycorrhizal metabolism which has the benefits in greengrocery and in seedlings propagation. In this work is also used good microscopical technologies, especially pictures which was taken by microscope. Thank to this was showed precise details of mycorrhiza anatomy and I can more clarified the all results of colonization rate. The practical part was focused on the study of the fungal colonization which had influence or not on selected vegetables. The aim was to evaluate the positive morphological development of the plants in mycorrhizal substrates and statistically confirm or not significant result.

Dynamics of carbon and phosphorus flows in arbuscular mycorrhizal symbiosis Mgr. Tereza Konvalinková (doctoral thesis) Abstract Arbuscular mycorrhizal fungi (AMF) are widespread and highly specialized root symbionts, which gain all of their carbon (C) from the hosts, supplying plants with mineral nutrients (particularly with phosphorus, P) in return. This thesis focuses on the size and flexibility of C and P flows in arbuscular mycorrhiza in relation to environmental conditions, in particular to light and P availability. The indications that the symbiotic flows are regulated actively by both partners are discussed. The main findings are presented as a compilation of separate scientific works (two research articles, one review and one book section). A glasshouse experiment has shown that both mycorrhizal benefits and mycorrhizal colonization of medic (Medicago truncatula) by an AMF species (R. irregularis) decline along the gradient of decreasing light intensity. Interestingly, morphological adaptation of medic to the long-term light deprivation was boosted by mycorrhiza, probably because of C demand of AMF and due to the improved nutrition of the mycorrhizal plants. On the other hand, sudden 6-day shading caused rapid decline of shoot P content of mycorrhizal plants, accompanied with the accumulation of P...
