Ekofiziološke značilnosti glive Cenangium ferruginosum Fr. na borih : doktorska disertacija = Ecophysiological characteristics of the fungus Cenangium ferruginosum Fr. on pines : doctoral dissertationJurc, DušanOpravljene so bile morfološke anaize konidiomov in apotecijev glive Cenangium ferruginosum, spremljan je bil razvoj simptomov bolezni in razvoj trosišč na vejah črnega bora. Glive običajno obiskuje ... anamorf v stromah že v februarju, vedno pred razvojem teleomorfa. Apoteciji sproščajo askospore do konca junija.Dolžina odmrlih delov vej, na kateri so rasli apoteciji, je povprečno merila 45 cm. Iz kvadratnega milimetra himenija se je na uro sporstilo med 2100 in 2800 askospor. Pomanjkanje vode v gojišču zmanjša rast micelija glive C. Ferruginosum bolj kot rast micelija Sphaeropsis sapinea in Naemacyclus niveus, ne raste pri dostopni vodi aW 0,95 in slabše raste pri aW 1 kot pri aW0,995. Rast gliv S.Sapinea in Phialaphora hoffmanii v atmosferi različnih koncentracij terpenskih ekstraktov borovih iglic iz treh podvrst črnega bora (Bled - Slovenija, Ceveni in Korzika - Francija) se ni razlikovala od kontrol brez terpenskega ekstrakta. Gliva C. ferruginosum pa je v atmosferi z največjokoncentracijo terpenov iz podvrste P. nigra ssp. Austriaca (Sloveniija), iz katere je bila izolirana, rasla najhitreje. Krošnja črnih borov na šestih poskusnih ploskvah so imele pozimi leta 2001/2002 povprečno 17% odmrlih iglic zaradi sušenja vej. Opravljene so bile izolacije iz 1575 koščkov skorje 525 odmrlih vej in iz 576 koščkov 192 zdravih vej. Iz odmrlih vej je zraslo 68 taksonov in določenih je bilo 35 vrst, iz zdravih vej je zraslo 14 taksonov in določenih je bilo 5 vrst. Odmiranje vej je v največji meri povzročila glivea S. sapinea (izolirana iz 64,4% okuženih vej). Domnevamopa, da so ob močni suši sposobne povzročiti odmiranje vej še naslednje izolirane glive: Hormonema dematioides, C. ferruginosum, Truncatellahartigii, Phomopsis occulta, Alternaria alternata in Trichoderma viride. Endofitno je od patogenov v skorji prosotna gliva H. dematioides. Število izolacij glive C. ferruginosum se je na splošno ujemalo s številom najdenih vej z apoteciji te glive.Type of material - dissertation ; adult, seriousPublication and manufacture - Ljubljana : [D.
