Povezanost morfoloških potez s potencialnimi alelopatskimi učinki kobulnic (Apiaceae) : magistrsko delo = Relation between morphological traits and potential allelopathic effect of umbellifers (Apiaceae) : master of science thesisMujdrica Rožman, AlenkaZaradi bogate zastopanosti evolucijsko zaokrožene in izredno divergirane skupine kobulnic na stičišču Srednje Evrope, Dinaridov in Alp ter Sredozemlja (Slovenija) smo se odločili poiskati povezavo ... med funkcionalnimi tipi in ekološkimi strategijami (izmerjenimi na osnovi morfološko-funkcionalnih potez) ter alelopatskim potencialom. Raziskava temelji na 41 izbranih vrstah kobulnic in proučevanju 13 morfološko-funkcionalnih potez teh rastlin in njihovimi alelopatskimi potenciali. Vzorčenje rastlin je potekalo na območju celotne Slovenije. Rezultati kažejo, da so izbrane kobulnice povečini hemikriptofiti (82,9 %), trajnice (73,2 %), prevladuje listnato ozelenelo steblo (92,6 %), so brez pritlik (85,3 %), povečini niso dlakave (60,9 %), največ jih zacveti v juniju (36,5 %) in juliju (46,3%) in večina konča cvetenje avgusta (51,2 %). V povprečju cvetijo 2 (39 %) ali 4 (34,1 %) mesece. Povprečne vrednosti SLA kažejo trend zviševanja z višino kobulnic. Povprečne vrednosti LDMC pokažejo trend zniževanja vrednosti LDMC z višanjem višine izbranih kobulnic. Korelacija pri visokih, srednje visokih in nizkih kobulnicah med vrednostjo LDMC in SLA kaže podoben trend nižanja vrednosti LDMC z naraščanjem vrednosti SLA. Rastlinskim vrstam smo določili 5 od 19 funkcionalnih tipov CSR- strategij: CR (39 %), C/CR (37 %), C (17 %) SC in S/SC v sledeh. Na osnovi naše raziskave lahko povzamemo, da imajo visoke kobulnice (120-180 cm) z velikimi listi C/CR-, CR- ali C- strategijo in potencialni alelopatski učinek. Nizke kobulnice (30-80 cm) z majhno listno povšino imajo CR- in CS- strategijo. Za te rastline ne moremo trditi, da nimajo potencialnega alelopatskega učinka. Alelopatski testi vodotopnih in hlapljivih substanc so pokazali, da imajo kobulnice povečini alelopatske učinke. Kobulnica Bupleurum veronense je edina, kateri nismo dokazali alelopatskih učinkovin. Potencialni alelopatski učinek pri kobulnicah lahko povežemo z odvisnostjo od višine rastlin, njihovo življenjsko obliko in življenjskim ciklom. Na zaviranje rasti drugih rastlin najbolj vplivajo kobulnice, ki so CR- strategi.Type of material - master's thesis ; adult, seriousPublication and manufacture - Maribor : [A.
