20.500.12556/DKUM-54084 Vpliv uporabe bakrovih pripravkov na vsebnost tokoferolov in karotenoidov v plodovih paradižnika The effect of cooper sprays on the tocopherols in tomato fruits V okviru magistrskega dela smo raziskali vpliv uporabe bakrovih pripravkov na vsebnost ɑ-tokoferola in karotenoidov v zrelih plodovih treh sort paradižnika ′Paki′, ′Monro′ in ′Optima′. Poskus je bil zasnovan na polju dve leti zapored. Rastline so bile v vegetacijski dobi škropljene z različnimi barkrovimi pripravki. V ekstraktih liofiliziranih vzorcev smo določili vsebnosti ɑ-tokoferola, luteina, fitoena, β-karotena in likopena s HPLC/PDA/FD. Najnižje vsebnosti posameznih karotenoidov so bile izmerjene v sorti ′Monro′, medtem ko se sorti ′Optima′ in ′Paki′ v vsebnosti skupnih karotenoidov nista razlikovali. Od karotenoidov je bil najbolj zastopan likopen in je predstavljal 76–80 % vseh karotenoidov. Vsebnosti ɑ-tokoferola v letu 2011 so bile med 106 mg/kg SS (′Monro′) in 148 mg/kg SS (′Optima′) in v letu 2012 med 101 (′Optima′) in 106 mg/kg SS (′Paki′). Interakcija sorta in škropilni program je bila značilna, kar pomeni, da se je vpliv škropilnega programa na vsebnost karotenoidov in α-tokoferola po sortah razlikoval. The aim of the master thesis was to investigate the effects of the application of copper sprays on the content of ɑ-tocopherol and carotenoids in mature fruits of three tomato cultivars ′Paki′, ′Monro′ and ′Optima′. The field experiment was carried out in two consecutive years. During the growth period, the plants were treated with different copper sprays. In extracts of the freeze-dried samples, the contents of α-tocopherol and carothenoids were determined by HPLC/PDA/FD. The lowest concentrations of individual carotenoids were determined in ′Monro′, whereas there were no differences in the carotenoids levels between ′Optima′ and ′Paki′. Lycopene was present in much higher amounts than other determined carotenoids and represented 76 –80% of the total carotenoids. The contents of α-tocopherol in 2011 were between 106 mg/kg DW in ′Monro′ and 148 mg/kg DW in ′Optima′, whereas in 2012 they ranged from 101 mg/kg DW in ′Optima′ and 106 mg/kg DW in ′Paki′. The cultivar x spray programme interaction was significant for the contents of carotenoids and α-tocopherol. paradižnik (Lycopersicum esculentum) posamezni karotenoidi ɑ -tokoferol bakrovi pripravki tomato (Lycopersicum esculentum) individual carotenoids α - tocopherol copper sprays true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2015-08-20 16:24:07 2015-08-28 09:25:39 2022-06-04 03:10:34 2021-05-09 03:32:41 2015 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:Z8BZ6DDV MAG_Zalokar_Damjana_2015.pdf MAG_Zalokar_Damjana_2015.pdf 1 020AE73A5832E6CF6B58C9CCAAEA3C04 3ff4b6d8e6a48bcfa7edb9760981e3548c65be0b04982a8daa863bfc809966ef a1ea1630-7c07-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=79540 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
