Wiederaufforstungsmaßnahme, Ektomykorrhiza, Symbiose, Isolation, Inokulation, Pinus thunbergii
The aim of the present investigation was the development of a model system for an improvement of a reforestation of extreme sites. As extreme locations here in particular, waste dumps, rubble and eroded locations in South Korea were considered. Two domestic Pinus species (Pinus thunbergii and Pinus densiflora) of South Korea and as mycobionts Pisolithus tinctorius, Suillus bovinus and Rhizopogon roseolus were selected. As soil substrates mainly forest soil, sand, and rubble were tested. Additionally, compost was used as an additive to improve the used soil substrates. In particular it was checked, with which tree species and which mycorrhiza an optimal plant growth and a good mycorrhizal formation can be obtained. A special emphasis became from mycorrhizal fungi in this case on optimization of an isolation means for the extraction of suitable pure cultures, mycorrhizal roots from the field and put the choice of the suitable symbiosis partners. In order to be able to judge the effect of soil parameters onto the development of the mycorrhiza and onto the plant growth, different soil parameters were determined as well as carried out a nutrient and pollutant analysis in the shoot and roots of mykorrhizal and non-mycorrhizal plants. The developed model system proved itself suitable for the processing of the performed question formulations. It also showed the effect of the mycorrhizal formation in the experimental approaches to the inoculation as well as the optimal combination are recognizable at that between the symbiosis partners. A precise and optimized selection of mycorrhizal fungi could lead to an improved growth of woods on extreme sites.
