20.500.12556/DKUM-16179 VSEBNOST KOVIN V RAZLIČNIH SORTAH JAGOD PRIDELANIH NA EKOLOŠKI IN INTEGRIRANI NAČIN A comparison of metal concentration in different varieties of strawberries grown according to organic and integrated production techniques. Leta 2009 smo odvzeli vzorce štirih sort jagod 'St.Pier', 'Elsanta', 'Sugar Lie' in 'Thuchampion' z namenom primerjati vsebnosti K, P, Mg, Fe, Mn, Cu in Zn v jagodah, pridelanih na ekološki in integriran način. Po ekstrakciji talnih vzorcev in po mikrovalovnem razklopu jagod, smo koncentracije kovin določili s spektroskopskimi tehnikami. Jagode, pridelane na integriran način, so pri vseh sortah vsebovale več K, P in Mg. Vrednosti Cu so bile višje pri ekološko pridelanih jagodah sorte 'Thuchampion'. Mn in Fe pa sta bila povečana v vseh sortah jagod, pridelanih na integriran način. Vzorci zemlje iz integrirane pridelave imajo višjo vsebnost Zn, K in P, kar je verjetno posledica gnojenja z NPK gnojili, vzorci zemlje iz ekološke pridelave pa so imeli višje vrednosti Cu, Mn, Mg in Fe. Rezultati so pokazali statistično pomembne razlike med sortami glede na način pridelave, glede na sorto pa so bile statistično pomembne razlike v vsebnosti vseh kovin z izjemo Zn. In 2009 we took samples of four strawberry varieties, i.e. 'St.Pier', 'Elsanta', 'Sugar Lie' and 'Thuchampion' with the aim to compare the contents of K, P, Mg, Fe, Mn, Cu and Zn in strawberries grown according to integrated and organic production techniques. After extracting soil samples and microwave digestion of strawberries, the concentrations of metals were determined by spectroscopic techniques. All varieties of non-organically grown strawberries contained higher levels of K, P and Mg. The Cu content was higher in organically produced 'Thuchampion' variety. The Mn and Fe concentrations were higher in all varieties in integrated production. Soil samples from integrated production contained higher levels of Zn, K and P, probably due to N-P-K fertilizers, while soil samples from organic production contained higher levels of Cu, Mn, Mg and Fe. According to production techniques, there were statistically significant differences in all varieties, while according to varieties we observed statistically significant differences in the contents of all metals, except for Zn. jagode / kovine / način pridelave strawberries / metals / production techniques true true false Slovenski jezik Angleški jezik Diplomsko delo 2010-10-04 10:39:00 2010-10-15 08:46:24 2022-04-13 07:56:14 2023-12-20 03:12:55 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:KZ97NV6L UNI_Brdnik_Janja_2010.pdf UNI_Brdnik_Janja_2010.pdf 1 BAC418EAEB89FF7C63BDA34AA4502D65 0420e7b9774ac76b4d14fb35939c43335f1c55e75b02ad398839beca6c13438c 8a9a5494-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/a741990b-225a-4e6b-88d4-ac3cd2487cee https://dk.um.si/Dokument.php?lang=slv&id=18201 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
