Abstrakt
The study describes the effect of soil moisture availability on mycorrhizal development and mycorrhizas vitality on Scots pine seedlings in bare root nursery. Seedlings grown under nursery conditions on sandy soil, were subjected to different watering regimes: 1– dry regime (non-watered), 2 – wet regime. Higher percentage of ectomycorrhizal short roots that had better vitality possessed seedlings from wet regime. Irrespective of treatment the same fungi were engaged in mycorrhizal colonization in both treatments with the exception of ectomycorrhizas of Cenoccum geophilum that were found only on seedlings from dry treatment. The content of ergosterol in seedling roots was the index allowing to determine the vitality of mycorrhizas.
