Background and Purpose: Pedunculate oak mortality and the success of regeneration are governed by changes in hydrological conditions. Excessive quantities of water in lowland forest ecosystems lead to site waterlogging. This event is assumed to have an unfavourable effect on forest trees and mycorrhizal symbiosis in the soil. The goal of research was to determine the impact of excessive substrate humidity and inoculation on the growth of pedunculate oak seedlings. Materials and Methods: Research involved inoculated and noninoculated pedunculate oak seedlings growing in a glasshouse in substrates with two different humidity levels. The inoculum of ectomycorrhizal fungus Laccaria bicolor S238 was made in a mixture of alainate and humus. Seedling diameters at root and at ha half height and heights of seedlings were analysed. Results: The height of pedunculate oak seedlings growing in an excessively humid substrate was 50% lower and the diameters at the root smaller in comparison with seedlings growing in favourably humid substrate. No significant differences in the heights of inoculated and non-inoculated pedunculate oa seedlings growing in the same humidity conditions were found. There were significant differences in diameters at the root in excessively humid substrate, but not in normal humidity conditions. No differences were found in diameters at half height. Conclusion: The growth of pedunculate oak seedlings and the ectomycorrhizal inoculation were considerably impacted by unfavourable hydrological conditions |
