20.500.12556/DKUM-78655 Analitične lastnosti nekaterih heirloom sort paradižnika. Analytical Properties of Certain Heirloom Tomato Varieties Heirloom sorte so komercialno manj zanimive sorte paradižnika, ki pa pridobivajo na veljavi, saj so dobro prilagojene lokalnim pridelovalnim razmeram in po lastnostih bolj raznolike. Analizirane so bile lastnosti 40 kultivarjev paradižnika, od teh 38 heirloom sort in dveh hibridov. Fiziološko zreli plodovi so bili umeščeni v osem vizualno določenih barvnih skupin (rdeči, roza, oranžni, beli, zeleni, rumeni, modri in črni). Izmerili smo jim velikost, maso, čvrstost in parametre barve (L*, a* in b*) ter s hitrimi laboratorijskimi testi vsebnost C-vitamina, suhe snovi in titracijskih kislin. Kultivarji se med seboj razlikujejo po parametrih barve, obliki in velikosti, vsebnosti suhe snovi in titracijskih kislin, medtem ko se po vsebnosti C-vitamina ne razlikujejo. Med rdečeplodnimi kultivarji ima največ C-vitamina 'Ded Moroz' (49,9 mg/100 g), vsebnost vitamina v obeh hibridnih kultivarjih 'Cherrola F1' (29,0 mg/100 g) in 'Mondial F1' (21,7 mg/100 g) je enaka vsebnosti v ostalih heirloom sortah (19,7–32,3 mg/100 g). Parametra vsebnost suhe snovi in C-vitamina nista v čvrsti korelaciji (rS = 0,304). Heirloom varieties are commercially less interesting varieties of tomatoes, but they are gaining in importance as they are well adapted to local growing conditions and more diverse in terms of characteristics. 40 tomato cultivars were analysed, of which 38 were heirloom varieties and two were hybrids. Physiologically ripe fruits were categorised in eight visually defined colour groups (red, pink, orange, white, green, yellow, blue and black) and their size, weight, firmness, and colour parameters (L*, a* in b*) were measured. Further analytical measurements were also performed via rapid laboratory tests for vitamin C content, soluble solids and titratable acids. The cultivars differed in colour parameters, shape and size, soluble solids content and titratable acids, while they did not differ in vitamin C content. Among red-fruited cultivars, ‘Ded Moroz’ had the highest vitamin C content (49.9 mg/100 g), the vitamin content in both hybrid cultivars 'Cherrola F1' (29.0 mg/100 g) and 'Mondial F1' (21.7 mg/100 g) was equal to the content in other heirloom varieties (19.7–32.3 mg/100 g). The parameters of soluble solids content and vitamin C were not in strong correlation (rS = 0.304). paradižnik heirloom sorte C-vitamin titracijske kisline suha snov Tomato Heiloom Varieties C-vitamin Titratable Acids Soluble solids true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2021-01-28 21:35:19 2021-02-10 09:57:31 2022-08-09 19:17:11 2021-02-11 03:27:40 2021 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:HS52AIRK MAG_Vogrin_Martina_2021.pdf MAG_Vogrin_Martina_2021.pdf 1 51E337DEB9A123CC8F2C864240F4104D 067de98e59b45a37fb7d8412aa87f21404ecbc5ee3e5dd2b587477faeaa88e62 1a7a7bee-7c12-11eb-bb7a-00155d0001ca 20.500.12556/dkum/82bd419b-ad2a-4b49-b56a-9771d1be791c https://dk.um.si/Dokument.php?lang=slv&id=148743 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
