41. Interakcije v mikorizosferi določajo dinamiko ogljika v ekosistemu bukovih gozdovTine Grebenc, Hojka Kraigher, 2009, original scientific article Abstract: Zaloga ogljika v gozdnih tleh je največji bazen terestičnih zalog organskega ogljika, njegova dinamika pa je vezana na talne, predvsem simbiontske organizme. Med najpomembnejše simbionte v gozdnih tleh, tako po vrstni kot funkcionalni pestrosti, sodijo ektomikorizne glive. V gozdnih ekosistemih v Sloveniji, v katerih prevladuje bukev, smo na osnovi morfoloških in molekularnih znakov identificirali večje število mikoriznih gliv in nekatere nove na kratko opisali. Na osnovi številčnosti posameznega tipa ektomikorize smo prvič izračunali prispevek tipa (vrste glive) ektomikorize k neposrednemu skladiščenju ogljika v ektomikorizi in v tleh v zgornjih plasteh tal (do globine 20 cm). Podatke o ogljiku, shranjenem v ektomikorizi, smo primerjali z modeliranimi količinami celotnega ogljika v gozdnih tleh, shematsko prikazali povezave in tokove ogljika ter pomen ektomikorize za dinamiko ogljika v gozdnih ekosistemih z bukvijo.

42. Identification of types of ectomycorrhizae on seedlings in a beech provenance trialMarjana Westergren, Tine Grebenc, Gregor Božič, Robert Brus, Hojka Kraigher, 2004, original scientific article Abstract: Root systems and types of ectomycorrhizae (ECM) were analysed on three 7-year-old beech seedlings (Fagus sylvatica L.) of three provenances (Val di Sella, Idrija, Nizbor) from an international beech provenance trial and on a naturally regenerated 5-year-old beech seedling from the same site (Kamenski vrh by Novo mesto). All short roots were mycorrhizal. In the sampled 20,302 root tips 49 % were non-turgescent and unidentifiable ECM. Twenty-two different types of ECM were identified, out of which 11 were successfully determined either to the species or genus level. All ECM were described by morphological and anatomical characteristics, basidiomycetes also by molecularmethods. ECM that was not successfully determined either to the species or genus level formed a new cluster in the Slovenian mycorrhizal molecular database. Species richness and percentage of vital ECM roots were highest for the provenance from Idrija (Slovenia). The results indicate that there might be differences between provenances regarding the abundance of ECM,which should be further studied.
