Summer truffle (Tuber aestivum), also known as Burgundy truffle, is getting interest in Poland in terms of cultivation as a promising incentive for rural areas. Yet the occurrence of the fungus in wider scale in our country has been confirmed in the last decade. Ecological factors that determine the occurrence of T. aestivum are rather well known in the Mediterranean region, whereas such knowledge...
Ectomycorrhizal communities associated with Pinus sylvestris growing on dry coniferous forest habitat after the fire were studied. In order to investigate the fire effect on ectomycorrhizal fungi and changes of soil parameters in the upper (0−15 cm) soil layer three study plots were established: 1 – the control, 2 – fire zone left for artificial renewal (with the economic method of renewal) and 3...
Edible forest mushrooms are one of the most important non−wood products and their economic importance is constantly growing. Only in Poland, the value of collected mushroom is estimated to about 740 million PLN a year. Such species as Boletus sp., Lactarius sp. or Tuber sp. are the most valuable non−wood forest products. Wild species, a great part of which are ectomycorrhizal fungi, not only play...
In this paper we discuss the data on presence of truffles (Tuber spp.) in Polish literature and culture through the ages. The aim of this article was to give the historical data on truffles as well as the new ones together with the ongoing research on that ultimate fungi. Study concerning widely understood history of and research on truffles in Poland was based on review of literature dating back...
Microorganisms commonly inhabit all environments in which they can survive. The number of bacteria in soil depends on its structure, moisture and nutrient content, and ranges from a few hundred to several thousand per gram of soil. Qualitative and quantitative composition of bacteria mainly depends on physico−chemical agents, soil and vegetation cover, the content of biogenic elements, but also on...
Celem prezentowanych badań było oznaczenie aktywności enzymów wydzielanych do podłoża przez dwie formy trufli letniej: Tuber aestivum i Tuber uncinatum Vittad. W pracy wykazano, że T. aestivum i T. uncinatum uwalniają do podłoża hodowlanego białka enzymatyczne o aktywności: lakazy, proteazy, lipazy oraz celulazy i ksylanazy. Analiza aktywności enzymatycznej w płynnych hodowlach obu form trufli letniej...
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...
An assessment of ectomycorrhizal fungi associated with Pinus sylvestris L. growing on abandoned post−agri− cultural soil was performed. The seedlings were growing at three different treatments of soil amendments (harvest residue, bark compost and sawdust). As a control treatment, the soil without any amendments was used. The comparison of ectomycorrhizal structure done ten years after the application...
Ectomycorrhizal communities associated with Pinus sylvestris L. saplings growing on abandoned post agricultural soils were studied. 1-year-old seedlings inoculated with either Suillus luteus Fr. or Thelephora terrestris (Ehrh.) Fr. had been outplanted on three sites. We investigated the long-term effect (6 and 8 years after outplanting) of inoculation on ectomycorrhizal composition and species richness...
