Ectomycorrhizal structure on scots pine seedlings inoculated with choosen mycorrhizal species and out planted in post agricultural and marginal land
The effect on quantity and quality of ectomycorrhizas after inoculation of Pinus sylvestris L. with three ectomycorrhizal (ECM) basidiomycetes: Suillus luteus (isolate 5409 IBL), Boletus pinicola (isolate 5406 IBL) and Hygrophorus olivaceoalbus (isolate Mykoflor), and possibility to increase mycorrhizal diversity on roots were investigated in soil of post-agricultural land. Five months after inoculation and planting seedlings inoculated with B. pinicola had 95% of all mycorrhizas on roots, and presence of 6 morphotypes was identified. Seedlings inoculated with S. luteus and H. olivoceoalbus had about 78% mycorrhizas and 5 morphotypes. Non-inoculated seedlings possessed also 5 morphotypes, but a smaller number of mycorrhizas – about 64%. On marginal land two different kinds of seedlings were planted: 1– bare-rooted and 2–containerised. Although differences were not statistically significant, greater number of mycorrhizas possessed seedlings from treatment 2. Morphotypes formed by Thelephora terrestris fungus colonized 80% of fine roots on seedlings from treatment 1, and 20% on seedlings from treatment 2. Results indicate that used fungi are worth further investigating to ascertain if they can promote pine growth.
