Analiza sladkorjev, aminokislin in fenolnih spojin v nektarju izbranih avtohtonih medovitih rastlinskih vrst
Katja Malovrh, Jože Bavcon, Mitja Križman
Doktorska disertacija
Oznake: aminokisline;fenolne spojine;medovite rastline;nektar;sladkorji;
V raziskavi smo preučevali nektar dvanajstih avtohtonih medovitih rastlinskih vrst. Zanimala nas je količina izločenega nektarja in njegova sestava, predvsem sladkorji, aminokisline ter fenolne spojine. Preučili smo tudi vpliv dela dneva na nektar in vpliv abiotskih dejavnikov, kot so temperatura zr ...

Analiza globalne metilacije citozina v DNA pri različnih genotipih konoplje (Cannabis sativa) gojenih v pogojih in vivo in in vitro z metodo HPLC
Luka Bonin, Jana Murovec, Mitja Križman
Diplomsko delo
Oznake: globalna DNA metilacija;HPLC;konoplja;epigenetske spremembe;5-metilcitozin;
Konoplja (Cannabis sativa L.) je gospodarsko vse pomembnejša rastlinska vrsta, pri kateri mikropropagacija omogoča hitro pridobivanje enotnega rastlinskega materiala. Daljše gojenje in vitro lahko sproži epigenetske spremembe, med katerimi je osrednjega pomena globalna metilacija DNA. Namen naloge j ...

Izvirni znanstveni članek
Oznake: amino acids;environmental factors;Galanthus;Helleborus;nectar composition;nectar secretion;phenolic compounds;sugars;pollinators;
Floral nectar is mainly a reward in the form of food for pollinators. In early spring, when snow can still be present, pollinators have trouble finding food. The composition and productivity of nectar in flowers play an important role in a pollinator’s life. It is known that low temperatures and low ...

Oznake: črni trn;glog;nektar;fenolne spojine;blackthorn;hawthorn;nectar;phenolic compounds;
Crataegus monogyna Jacq. and Prunus spinosa L. are common spring-flowering species in Slovenia. They occur in large stands and sometimes overgrow in unmanaged meadows. They are known as an excellent source of nectar for bees and other pollinators. Phenolic compounds are known as antioxidant for both ...
