1. Imenšek, Nataša. Vsebnost skupnih fenolov v nekaterih vrstah bezga in njihovih križancih.

Degree: 2016, Univerza v Mariboru

V sklopu magistrskega dela smo analizirali vsebnost skupnih fenolov pri več kot 40 rastlinah bezga, med njimi so bili nekateri karakteristični genotipi črnega bezga (Sambucus nigra L.), modri bezeg (S. nigra ssp. cerulea (Raf.) R. Bolli), habat (S. ebulus L.) in nekateri medvrstni križanci, ki so vključevali javanski (S. javanica Blume), črni, rdeči (S. racemosa L.) in modri bezeg. Izvedli smo ekstrakcije vzorcev in s Folin-Ciocalteu reagentom določili vsebnost fenolnih spojin. S pomočjo molekulske absorpcijske spektrometrije (MAS) smo izmerili koncentracije skupnih fenolov v ekstraktih mladih listov, socvetij in plodov (jagod). Povprečno vrednost vsebnosti skupnih fenolov v posameznih delih bezgovih rastlin smo podali v mg GAE (ekvivalent galne kisline)/100 g vzorca. Rezultati so pokazali, da vsebujejo jagode povprečno 619 mg GAE/100 g vzorca (na svežo snov) oziroma 3159 mg GAE/100 g (na suho snov), listi 7074 mg GAE/100 g (na suho snov) in cvetovi 6631 mg GAE/100 g (na suho snov). Rezultati kažejo, da obstajajo glede na vsebnost skupnih fenolov velike razlike med posameznimi genotipi.

The aim of the presented research was to analyze the content of total phenolics in more than 40 elderberry plants. The analysis involved several characteristic genotypes of black elder (Sambucus nigra L.), blue elder (S. nigra ssp. cerulea (Raf.) R. Bolli), European dwarf elder (S. ebulus L.), and some interspecific hybrids involving Chinese elder (S. javanica Blume), black elder, red elder (S. racemosa L.) and blue elder. After the extraction of samples we determined the content of phenolic compounds using Folin-Ciocalteu reagent. We measured the concentration of total phenolics in the extracts of young leaves, inflorescences and fruits (berries) using molecular absorption spectrometry (MAS). The results were expressed in mg of gallic acid equivalent (GAE) per 100 g of sample. The results showed that the total phenolic content in berries was on average 619 mg GAE/100 g (based on a fresh matter) or 3159 mg GAE/100 g (based on dry matter), in leaves 7074 mg GAE/100 g (based on dry matter) and in inflorescences 6631 mg GAE/100 g (based on dry matter). There were statistically significant differences among studied genotypes.

2. Zafošnik, Irena. Reproduktivne značilnosti medvrstnega križanca Sambucus javanica x S. ebulus.

Degree: 2015, Univerza v Mariboru

V magistrski nalogi smo primerjali glavne morfološke lastnosti listov in reproduktivnih organov starševskih vrst (S. javanica 'ES' in S. ebulus) ter njunega medvrstnega križanca (S. javanica × S. ebulus). Ker je križanec sterilen, je bil eden od pomembnih ciljev raziskati vzroke sterilnosti na nivoju materinskih celic pelodnih zrn. Ugotovili smo, da so nekatere morfološke lastnosti križanca precej podobne morfološkim lastnostim starševskih vrst. Citološka analiza, ki je temeljila na opazovanju kromosomov mikrosporocit, je pokazala, da sta bila oba starša (S. javanica ES in S. ebulus) diploida z 2n = 36, medtem ko smo pri medvrstnem križancu opazili velike variacije v številu kromosomov in nepravilnosti v celični delitvi. Prisotna je bila anevploidija, in sicer od hiper-diploidije do hipo- in hiper-tri- in tetraploidije. Na podlagi citološke analize sklepamo, da je sterilnost medvrstnega križanca posledica anevploidije, ki je povezana z nepravilnostmi v mikro- in makrosporogenezi.

In the presented MSci thesis, we compared main morphological and reproductive characteristics of the parental species S. javanica 'EC' and S. ebulus, and their interspecific hybrid (S. javanica × S. ebulus). We also analyzed the reasons of reproductive sterility of the hybrid plants. It was found that some morphological characteristics of the hybrid plants were more similar to one or another parental species, whereas the others varied between the parental species. The cytological analysis based on microsporocytes showed that both parents (S. javanica and S. ebulus EC) were diploids with 2n = 36. The interspecific hybrid plants exhibited various types of aneuploidy (variations of the number of chromosomes such as hypo- and hipper- di-, three- and tetraploidy) as well as abnormalities in cell division. The investigation showed that sterility of interspecific hybrid plants was probably caused by aneuploidy and its association with irregularities in micro- and macrosporogenesis.
