Abstract :

The purpose of this study is to determine the effects of vegetative and liquid inoculum applications ofLactarius pyrogalus, an ectomycorrhizal mushroom associated with hazelnut (Corylus avellana), on thegrowth of hazelnut seedlings. In the study, 7 different inoculum applications were examined and 5seedlings were grown for each application. At the end of the cultivation period of 3 months,ectomycorrhizae formation and plant growth in the seedlings were evaluated. Ectomycorrhizalformation was observed in all inoculum applications, except for non-inoculated seedlings in the controlapplication. Plant height, stem diameter, root length, root wet and dry weight, shoot wet and dry weight, total plant dry weight, root:shoot ratio, root and shoot dry matter content in seedlings belonging todifferent inoculum applications were determined. The effect of different inoculum applications on allother properties examined except for root:shoot ratio and shoot dry matter content was found statistically significant. When the plant growth parameters and mycorrhizal inoculation efficiency (MIE) were evaluated together, the best results were obtained from the application which wasmoistened with without sugar Modified Melin-Norkrans (MMN) nutrient medium and used vegetativeinoculum. As a result, it was determined that inoculation made by using different inoculums of L.pyrogalus provided positive contributions to the growth of hazelnut seedlings.
