20.500.12556/DKUM-16744 Nekateri problemi, povezani z oblikovanjem in karakterizacijo križancev vrtnic Study of basic problems related to the crossings and characterisation of rose hybrids Raziskava je potekala med leti 2006 in 2010 v kraju Šmarjeta in v Novem mestu. Glavni namen raziskave je preverjanje tehnike križanja in kalitev semen ter proučitev glavnih problemov, ki se lahko pojavijo pri vzgoji in karakterizaciji starševskih komponent ter njihovih potomcev. Pri starševskih rastlinah in potomcih smo proučevali barvo in obliko cvetov ter obliko čašnih listov. Analizirane so bile tudi nekatere kvantitativne lastnosti listov in trnavost. Raziskava je pokazala, da rastlinice lahko zacvetijo že v letu vznika, vendar barva in oblika cveta v prvem letu ne prideta do končnega izraza. Oblika čašnih listov je zelo variirala in najverjetneje ne bi bila uporabna za karakterizacijo posameznih genotipov. Med kvantitativnimi lastnostmi je bila največja variabilnost ugotovljena pri dolžini peclja lista, najmanjša pa pri dolžini bazalnega lista. Najbolj čvrste korelacijske povezave so bile ugotovljene pri dimenzijah listov. Pri analizi trnavosti smo ugotovili, da so bile razlike znotraj posameznih materialov prevelike in zato jih ni bilo mogoče uporabiti za opisovanje posameznih genotipov. The research was carried out between 2006 and 2010 in Šmarjeta and Novo mesto (southern part of Slovenia). The main purpose of this study was to examine the technique of hybridization and seed germination, and the main issues that may arise during upbringing and characterization of the parental material and their descendants. In the case of parental plants and their offsprings, we studied color and shape of flowers and shape of sepals. We also analyzed some quantitative characteristics of leaves and thorns (on the stems). The study showed that some plants may flower already in the year of germination, but the color and shape of a flower in the first year are not fully expressed. The shape of sepals and leaves were highly variable and could not be used for characterization of individual genotypes. Among the quantitative characteristics, the most variable was the length of leaf petiole, whereas the most uniform was the length of the basal leaflet. The strongest correlation was established between leaflet dimensions. Regarding thorns, the differences within individual materials were too high and therefore could not be used as descriptors for individual genotypes. vrtnice Rosa spp. križanje kvantitativne lastnosti roses Rosa spp. hybridization quantitative traits true true false Slovenski jezik Angleški jezik Diplomsko delo 2010-11-16 17:38:30 2010-11-30 14:40:14 2022-04-13 08:52:32 2023-12-21 03:15:28 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:AFLPEXUN UNI_Grnovic_Branka_2010.pdf UNI_Grnovic_Branka_2010.pdf 1 636957D24EA07AE965C09DA4ED49BD3B b0059b3c6b012deda1b074bff1b6b01f8df86d820123f507b7b47a7aa29bde1b b8543885-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/f6ecf704-0d8a-4a3b-a58c-c008411ba29f https://dk.um.si/Dokument.php?lang=slv&id=19133 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
