Mineralne, petrološke in geokemične značilnosti berilovih pegmatitnih žil J-JV Pohorja
Mihael Ravnjak, Nina Zupančič, Miloš Miler
Magistrsko delo
Oznake: granat;turmalin;tantalit;kolumbit;REE;kemična sestava;
Na območju Pohorja se v granodioritu, kremenovem monzogabbru in metamorfnih kamninah pojavlja veliko pegmatitnih žil. Na J–JV delu masiva smo določili makroskopske, mikroskopske in geokemične značilnosti berilovih pegmatitov. Namen naloge je ugotoviti povečane vsebnosti slednih prvin, minerale, ki s ...

Understorey species distinguish late successional and ancient forests after decades of minimum human intervention
Mirjana Šipek, Tim Ravnjak, Nina Šajna
Izvirni znanstveni članek
Oznake: forest community;successional forest;indicator plants;plant diversity;understorey;geophyte;Slovenia;ne zaključna dela;
The main species composition drivers in temperate deciduous forests are environmental conditions, a stand's age and the site history, e.g., the succession stage and past land use, as well as disturbance regime and current management. We compared plant species diversity and composition in late succes ...

Phenolic compounds of rose hips of some rosa species and their hybrids native grown in the south-west of Slovenia during a two-year period (2020–2021)
Nina Kunc, Metka Hudina, Gregor Osterc, Jože Bavcon, Blanka Ravnjak, Maja Mikulič Petkovšek
Izvirni znanstveni članek
Oznake: rosa;Rosa corymbifera;Rosa glauca;Rosa subcanina;Rosa gallica;phenolic compounds;HPLC;extraction;
The genus Rosa is very extensive and variable, so it remains very unpredictable and uninvestigated. This also holds true for values of secondary metabolites in rose hips, which are important for several purposes (human diet, protection of plants against pests, etc.). The aim of our study was to dete ...

Detailed metabolic characterization of flowers and hips of Rosa gallica L. grown in open nature
Nina Kunc, Metka Hudina, Maja Mikulič Petkovšek, Jože Bavcon, Blanka Ravnjak, Gregor Osterc
Izvirni znanstveni članek
Oznake: Rosa gallica;Rosa subcanina;bioactive compounds;petals;rosehips;HPLC;secondary metabolites;primary metabolites;
Our research aimed to investigate the primary and secondary metabolites of rosehips and petals of R. gallica in comparison with R. subcanina. R. gallica was chosen because it is still unexplored in terms of various bioactive substances and is strongly present in Slovenia. Given that roses are genera ...

Autochthonous rose hybrid Rosa pendulina X spinosissima overshines main genotype Rosa pendulina in the biochemical characteristics of their hips
Nina Kunc, Maja Mikulič Petkovšek, Metka Hudina, Jože Bavcon, Branko Vreš, Gregor Osterc, Blanka Ravnjak
Izvirni znanstveni članek
Oznake: šipek;Rosa pendula;Rosa pendulina X spinosissima;biokemične spojine;kemična sestava;Rosa pendulina;biochemical compounds;rose hips;
The medicinal value of rose hips largely depends on the contents of vitamin C and flavonoids. Rose hips contain more vitamin C than most fruits and vegetables. We were particularly interested in how the bioactive substances of rose hips are inherited from main rose species. The aim of the study was ...

Characterization of the Slovene autochthonous rose hybrid Rosa pendulina × spinosissima (Rosa reversa Waldst. and Kit) using biochemical patterns of the plant blossoms
Nina Kunc, Metka Hudina, Jože Bavcon, Branko Vreš, Zlata Luthar, Kristina Ilnikar, Maja Mikulič Petkovšek, Gregor Osterc, Blanka Ravnjak
Izvirni znanstveni članek
Oznake: autochthonous rose;HPLC-MS;flow cytometry;hybrids;phenols;Rosa pendulina;Rosa spinosissima;Rosa pendulina x spinosissima;
The Rosa genus is characterized by great variability and, consequently, they easily hybridize. The petals of R. pendulina, R. spinosissima and their hybrid Rosa pendulina x spinosissima, collected in western Slovenia, were included in the research. We performed morphometric analysis using keys to de ...
