Nematofavna njivskih tal Slovenije in vpliv gostiteljskih rastlin na biopotencial in morfometrijske značilnosti Pratylenchus crenatus Loof, 1960 = Nematofauna of field soil in Slovenia and the effect of host plants on the biopotential and morphometrical characteristics of Pratylenchus crenatus Loof, 1960 : doktorska disertacija : dissertation thesisUrek, GregorPopulacijska dinamika Pratylenchus crenatus Loof, ki smo jo spremljali v njivskih tleh v letih 1993 in 1994, je bila močno razgibana, saj se je v sušnem obdobju obeh preučevanih let zelo zmanjšala, ... narastla pa je v spomladanskem in jesenskem obdobju. Nagel porast populacijske gostote v tleh so med letom povzročili tudi posamezni agrotehnični ukrepi, ki so prisilno vplivali na imigracijo P. crenatus iz korenin v tla. V sklopu preučevanja nematofavne njivskih tal Slovenije smo na podlagi morfološko anatomskih znamenj ogorčic izločili in taksonomsko razvrstili 86 rodov, od katerih jih je bilo šest fitofagnih (Basiria, Beleodorus, Miculenchus, Quinsulcius, Sakia, Zygotylenchus), devet plenilskih (Brachoncholus, Cobbonchus, Iotonchus, Nullonchus, Seinura, Tobrilus, Triplonchium, Tripyla, Tygronchus), trije fungivorni (Neopsilenchus, Neotylenchus, Nothotylenchus), osem rodov, ki jih nismo mogli razvrstiti v nobeno trofično skupino (Chromadora, Protorhabditis, Brestiania, Chronogaster, Monhystera, Monochromadora, Odontolaimus, Paraplectonema), in dvanajst rodov iz skupine Dorylaimid (Amphidorylaimus, Aporcelaimus, Doryllium, Labronema, Longidorella, Lordellonema, Nygellus, Oxydirus, Prodorylaimus, Thorneella, Thornenema, Tylencholaimellus), novih za naše ozemlje. Določili smo tudi 56 vrst fitofagnih ogorčic, od katerih jih je bilo 31 prvič ugotovljenih v obdelovalnih tleh Slovenije. Vse določene vrste in rodove smo vgradili v zoogeografski sistem razvrščanja, ki temelji na UTM mreži. V obdelovalnih tleh Slovenije smo ugotovili 9 Pratylenchus vrst: P. penetrans, P. pratensis, P. crenatus, P. thornei, P. neglectus, P. scribneri, P. pseudopratensis, P. convallariae, P. hexincisus, od katerih jih je bilo šest novih za naše ozemlje. Pri ugotavljanju vpliva gostiteljskih rastlin na biopotencial P. crenatus smo ugotovili, da pšenica, koruza, ajda, navadna ogrščica, breskova dresen, navadni repik, hudoletnica in navadna milnica statistično značilno vplivajo na populacijsko gostoto P. crenatus. Najboljši gostitelj je bila hudoletnica, najslabši pa pšenica. Pri preučevanju vpliva prekinitve rasti gostiteljskih rastlin smo ugotovili, da njihova vitalnost oziroma hiranje statistično značilno vplivata na populacijsko gostoto P. crenatus v koreninah oziroma tleh. Gostiteljske rastline: ajda, navadna ogrščica in breskova dresen, na katerih so se prehranjevale ogorčice, so statistično značilno vplivale na dolžino in širino P. crenatus ter na parametre: O/I, w. st., m. b., a, b, bl, S in Ž. Različne talne reakcije statistično značilno vplivajo na nematopopulacijski sestav v tleh. Bolj kisla tla so v naših poskusih bolj ustrezala P. crenatus in v poskusu uporabljenim fitofagnim ogorčicam, manj kisla oziroma nevtralna tla pa so bila primernejša za bakteriotvorne ogorčice. Na populacijo ogorčic v tleh je vplival tudi tip tal. Ugotovili smo tudi neposredni vpliv P. crenatus Loof., Gibberella zeae /Schw./ Petch. = Fusarium graminearum Schwabe in Thanatheporus cucumeris /Frank./ Donk. = Rhizoctonia solani Kühn na vsebnost N, amonijskega in nitratnega dušika ter amonijskih in nitratnih ionov v koruzi, vpliva na ostale makro in mikroelemente pa nismo ugotovili.Type of material - dissertation ; adult, seriousPublication and manufacture - Ljubljana : [G.
