Opis:: This study describes the effect of watering on the mycorrhizal development and growth of Scots pine seedlings in a bare root nursery. Seedlings of Scots pine, grown under nursery conditions on natural soil (loamy sand) and soil + litter, were subjected to two different watering regimes for five months. During this time, measurements of soil water potential were made. Seedlings grown in natural soil and subjected to drought conditions were of significantly greater shoot height and volume and they had one mycorrhizal morphotype more than watered seedlings. However, irrigated seedlings subjected to excessive watering possessed greater mycorrhizal colonization: 46% on natural soil and 72% on soil + litter, while non-irrigated seedlings had 36% and 67% levels of mycorrhizal colonization, respectively.

Opis:: Thelephora terrestris(Erhr.) Fr. is a very common ectomycorrhizal symbiont (ECM) in conifer trees, however the role of this ubiquitous fungus in nurseries and Scots pine plantations is still unknown. It is described as tolerant of high nitrogen availability and therefore was taken into consideration as an important ECM partner of seedlings, particularly after replanting on post agricultural land. In laboratory the seedlings of Scots pine (Pinus sylvestris L.) were inoculated with T. terrestris(Tt/IBL/2) or not inoculated (control) and grown in containers in two different regimes of nitrogen fertilization (4g N x kg-1and 6 g N x kg-1). Next year these seedlings were outplanted in post agricultural land and 6 months later, the number and identity of some mycorrhizas were studied. It was found, that mycorrhizal abundance was higher in the inoculated treatments than in non-inoculated ones. PCR RFLP analysis confirmed share of two different isolates of Thelephoraengaged in mycorrhizal symbiosis. Part of mycorrhizas had the same pattern of RFLP as the isolate used to inoculation. Similar results were obtained in second year of experimental study in the field what confirmed the persistence of artificially introduced T. terrestrisin post agricultural soil as an important component of the ECM community.
Sadzonki sosny zwyczajnej Pinus sylvestrisL., mikoryzowane grzybnią Thelephora terrestris i nie mikoryzowane (kontrola) hodowano w laboratorium w dwóch wariantach nawożenia (4g N x kg-1 and 6 g N x kg -1) a po roku wysadzono na gruncie porolnym. W ciągu dwóch sezonów wegetacyjnych badano stan ilościowy i jakościowy mikoryz oraz określono tożsamość partnera grzybowego. Wyższą ogólną liczbą mikoryz charakteryzowały się sadzonki sztucznie mikoryzowane. Analiza DNA grzybowego przeprowadzona metodą PCR RFLP wykazała, że na badanych korzeniach mikoryzy T. terrestristworzone były przez dwa izolaty Thelephora; izolat użyty do inokulacji siewek (Thelephora I) i izolat obecny w glebie (Thelephora II). Mikoryzy tworzone z udziałem inokulowanej grzybni obecne były na korzeniach jeszcze w dwa lata po wysadzeniu sadzonek na gruncie porolnym i stanowiły 30% udziału, podczas gdy mikoryzy autochtoniczne Thelephora II – 70%.

Opis:: Fungi belonging to the genus Tuber establish ectomycorrhizal symbioses with shrubs, trees and some herbaceous plants. Some Tuber species, for example, T. melanosporum, T. magnatum, T. aestivum are economically important because they produce edible fruiting bodies with a distinctive taste and flavor. Our concept of truffle ecophysiology is dominated by the symbiosis with deciduous hosts, such as: Quercus spp., Fagus sylvatica, Castanea sativa, Corylus spp., Carpinus betulus, Ostrya carpinifolia, Betula verrucosa, and Tilia spp., whereas the real range of hosts in nature seems to be much wider. Moreover, interactions between Tuber mycelium and plant community could be more complex than just forming the ectomycorrhizal symbiosis. Here we show our inventory of plants and soils at six truffle’ sites in the southern part of Poland (Nida Basin and Przedbórz Upland). The aim of this study was to widen our understanding of ecological factors affecting Tuber spp., in the context of pioneering stage of research on truffles in Poland. We hope our findings will have a practical application and will help to choose suitable soils for truffle orchards.
