Biodiversity of types of ectomycorrhizae in a norway spruce stands on PokljukaVilhar, Urša, 1977- ...V majhni vrzeli domnevno avtohtonega smrekovega sestoja na Pokljuki (Triglavski narodni park) smo proučevali tipe ektomikorize na smreki. Vzorce tal smo jemali na 33. zvezdasto razporejenih vzorčnih ... ploskvicah s sondo prostornine 274 ml iz globine 0-18 cm. Iz vsakega vzorca smo izločili vse koreninice smreke, jih prešteli, ter na kratko opisali prisotni tip ektomikorize. Izračunali smo Indeks bogastva vrst (d) in Shannonov indeks pestrosti (H). Zanimal nas je vpliv ekoloških dejavnikov (svetlobnih razmer, naravnega pomlajevanja, zastiranja vegetacije) na porazdelitev tipov ektomikorize. Od skupno 50.000 korenin smreke je bilo približno 1 % nemikoriznih, 63 % je bilo nedoločljivih, pretežno starih tipov ektomikorize ter 36 % določljivih ektomikoriznih korenin, ki so skupaj tvorile 27 tipov ektomikorize. Predstavljenih je 16 kratkih opisov za do sedaj neopisane tipe ektomikorize. Shannonov indeks pestrosti za tipe ektomikorize (3,13) je visok glede na pestrost vegetacije (1,7). Ugotovili smo negativno korelacijo direktnega sončnega sevanja s tipom ~Piceirhiza cornuta. Difuzno sončno sevanje je v negativni odvisnosti s tipom Cortinarius sp. (obtusus tip) in v pozitivni odvisnosti s tipom Inocybe sp.. Zastiranje pritalne vegetacije je v pozitivni odvisnosti s tipom Piceirhiza gelatinosa, skupno zastiranje vegetacije pa je v pozitivni odvisnosti s tipom Elaphomyces sp.Source: Zbornik gozdarstva in lesarstva = Research reports : forest and wood science & technology. - ISSN 0351-3114 (Št. 75, 2004 [i.e. 2005], str. 71-85)Type of material - article, component partPublish date - 2004Language - englishCOBISS.SI-ID - 1437094
