New information from a survey of truffles carried out in southern part of Poland in September 2007 is presented. The fruit bodies of Tuber aestivum, T. excavatum, T. rufum and one unidentified Tuber sp. were found. The soil chemistry of the five T. aestivum sites was analysed. Our inventory showed that T. aestivum prefers the mixed forest with host-trees(More)
This paper describes the specifics of forests on former farmlands in Poland and their protection as well as preventive measures taken. The review refers to polish literature on the threat by root rot caused by Heterobasidion annosum (Fr.) Bref. to pine and spruce plantations established on postagricultural lands on an area of more than 1400 000 ha. In(More)
• We investigated the influence of Thelephora terrestris, an ectomycorrhizal fungus, on the concentration of nitrogen in needles of Pinus sylvestris L. seedlings and their mycorrhizal structure within four seasons of growth. • Seedlings were grown in four treatments: (I) inoculated + 0.030 g N, (II) inoculated + 0.045 g N, (III non-inoculated + 0.030 g N,(More)
 The effects of exposure to helium-neon (He-Ne) or Argon (Ar) laser light (λ=632.8 nm and 514 nm, respectively) on the growth of Hebeloma mesophaeum mycelium in pure culture were studied. Growth rates were highest after exposure to the He-Ne laser (1×60 s)+Ar laser (2×60 s) and to the He-Ne laser for 3×30. Container-grown Pinus sylvestris (pine) seedlings(More)
 HPLC chromatographic analyses of some phenolic acids in phloem of 1-year-old shoots sampled from 32 trees of eight Polish provenances of Scots pine (Pinus sylvestris L.) growing under conditions of annosum root [Heterobasidion annosum (Fr.) Bref.] are discussed. Considerable quantitative and qualitative differentiation was found among individual trees. The(More)
Their hyphal structure, the common events of hybridization and horizontal gene transfer, as well as intimate associations with prokaryotes (including endobiotic bacteria) and cooperation with eukaryotes have made fungi very flexible at the genetic, physiological, and ecological levels. It is manifested with the fungal ability to perfectly exploit existing(More)
