Polifenolne snovi kot kazalniki nezdružljivosti različnih podlag (Prunus spp. L.) in kultivarjev češenj (Prunus avium L.) : doktorska disertacija = Polyphenols as indicators of incompatibility of different cherry rootstocks (Prunus spp. L.) and cultivars (Prunus avium L.) : doctoral thesisUsenik, ValentinaV raziskavi smo ugotavljali vpliv različnih podlag za češnje za polifenolni vzorec kultivarja. Proučili smo vsebnost polifenolnih snovi pri drevesih z znaki inkompatibilnosti in možnosti zgodnjega ... odkrivanja inkompatibilnosti med kultivarjem in podlago na osnovi analize polifelnolnih snovi. Vsebnosti polifenolnih snovi smo določali s HPLC analizo v floemu nad in pod cepljenim mestom, v floemu mladik in vejic ter v listih triletnih dreves cv. 'Lapins', ki so bila cepljena na podlage F 12/1, Gisela 4, Gisela 5, Gisela 195/20, Maxma 14, Pi-Ku 4/20, Edabriz, W 13, W 72, W 158, sejanec češnje in Colt ter pri cv. 'Big Lory', 'Summit' in 'Vega', cepljenih na podlago sejanec češnje. V floemu češenj smo določili: katehin, epikatehin, eriodiktiol 7-glukozid, p-kumarno kislino, genistein, dihidrovogonin 7-glukozid in prunin, v listih pa klorogensko kislino, eriodiktol 7-glukozid in rutin. Ugotovili smo, da so podlage vplivale na različen polifenolni vzorec kultivarja 'Lapins' v floemu nad in pod cepljenim mestom, v floemu mladik in vejic ter v listih. Koncentracije fenolnih snovi so bile različne med rastno dobo in mirovanjem. Ugotivili smo statistično značilne razlike v vsebnosti katehina, eriodiktiol 7-glukozida, dihidrovogonin 7-glukozida, p-kumarne kisline in prunina v floemucv. 'Lapinds' glede na različne podlage pod cepljenim mestom ter v vsebnosti genisteina nad cepljenim mestom. Drevesa cv. 'Lapins' , cepljena na podlage Gisela 4, Gisela 5, Gisela 195/20, Pi-Ku 4/20, Edabriz, W 13, W 72 in W 158 (heterogenske kombinacije) so imela manj katehina v floemu pod cepljenim mestom in manj katehina v mladikah in vejicah: več epikatehina v floemu nad in pod cepljenim mestom; več epikaterhina v floemu nad in pod vepljenim mestom; več eriodiktiol 7-glukozida v floemu pod cepljenim mestom; drugačno razmerje p-kumarne kislinein dihidrovogonin 7-glukozida nad in pod cepljenim mestom (večja vsebnost nad cepljenim mestom); več genisteina nad in pod cepljenim mestom; povprečno več prunina v floemu nad in pod cepljenim mestom ter več klorogenskekisline v listih kot homogenska kombinacija (cv. 'Lapins'/F 12/1). Višje vrednosti epikatehina, eriodiktiol 7-glukozida, genisteina, prunina in drugačno razmerje p-kumarne kisline ter dihidrovogonin 7-glukozida pri heterogenskih kombinacijah kaže, da lahko podlage za češnjo, ki so hibridi ali kloni različnih vrst iz rodu Prunus, vplivajo na hitrejši propad češnjevih dreves. Ugotovili smo, da so bile koncentracije epikatehina, eriodiktiol 7-glukozida, p-kumarne kisline, genisteina in dihidrovogonin 7-glukozida pri drevesih z znaki inkompatibilnosti (cv. 'Big Lory', 'Vega' in 'Summit') različne koncentracije fenolnih snovi zdravih dreves. Razlike so bile tudi v vsebnosti klorogenske kisline, eridiktiol 7-glukozida in rutina med listi dreves z znaki inkompatibilnosti in zdravimi drevesi.Type of material - dissertation ; adult, seriousPublication and manufacture - Ljubljana : [V.
