Struktura ektomikoryz i parametry biometryczne sosny po wysadzeniu na gruncie porolnym

The focus of the research was on the effect of inoculation with the ectomycorrhizal fungus Thelephora terrestris on changes in mycorrhizal structure and growth parameters of Scots pine (Pinus sylvestris L.) seedlings. Before planting on post−agricultural land, the seedlings were grown under laboratory conditions for six months, at two different nitrogen fertilization rates [Hilszczańska, Sierota 2006a]. Mycorrhizae formed by T. terrestris dominated in the mycorrhizal structure during two growing seasons after planting irrespective of the growth variant applied. However, their higher percentage was detected in seedlings artificially inoculated with T. terrestris mycelium. The inoculation did not limit mycorrhiza formation by other mycorrhizal fungi. No significant differences in parameter values were found between inoculated and non−inoculated seedlings.
