| dc.description.abstract | I examined the effect of Frankia spp. and ectomycorrhizal fungi on green alder (Alnus viridis ssp. crispa), growing in nutrient-poor soil and saline conditions. The first experiment involved inoculating green alder growing in low fertility soil with three species of ectomycorrhizal fungi (Lactarius torminosus, Lactarius theiogalus, Hebeloma crustuliniforme) alone or in combination, with and without Frankia spp. on. Frankia spp. inoculation significantly increased plant performance compared to non-Frankia treatments. However, nodulated plant total biomass decreased with an increasing number of fungi. The second experiment examined the effect of Hebeloma crustuliniforme and Frankia spp. on green alder exposed to 0, 50 and 100 mM NaCl. Frankia spp. inoculation showed significant increase on plant performance but Hebeloma crustuliniforme did not. Plant mass, root:shoot ratio, nodule allocation and total nitrogen fixation decreased with NaCl exposure. A decrease in root:shoot ratio caused by salt was more moderate in nodulated plants compared to non-nodulated plants. | en_US |
