Seres A., Posta K., Bakonyi G., Nagy P., Kiss I., Fábián M., Répási V., Nosek J.N.: Collembola decrease the nitrogen uptake of maize through arbuscular mycorrhiza. Ekológia (Bratislava), Vol. 29, No. 3, p. 242-247, 2009.,There is little information on how AMF (arbuscular mycorrhizal fungi) functions are influenced by Collembola. In this experiment the question was addressed whether the presence of Collembola may decrease the nitrogen uptake of maize plant through AM-fungi system. A microcosm experiment was set up on the field. The microcosms were separated into two compartments by a screen of 42 pjn mesh size. A maize seedling was planted in one compartment of each microcosm. A mycorrhizal inoculum of Glomus mosseae and Gigaspora rosea was propagated into the soil. 15N marked ammonium sulphate was applied at a distance of 0.15 m from the plant in the root-free compartment of the microcosms with or without Collembola (Sinella coeca). Hyphal length, N and 15N content of the maize plants and the microbial biomass in the root-free compartment were significantly decreased in the presence of S. coeca. Presumably, Collembola destructed AMF hyphal network that led to decreased nitrogen uptake of plants.
