Analiza sladkorjev, aminokislin in fenolnih spojin v nektarju izbranih avtohtonih medovitih rastlinskih vrst : raziskovalni podatki, obravnavani v doktorskem delu

Malovrh, Katja (author)

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 zraka ter prsti, vlažnosti prsti in zraka ter UVB sevanje. Vzorce nektarja smo pridobili z metodo s kapilarami in pranja cvetov v naravnem okolju v Ljubljani ter okolici. Preverili smo, ali sta obe metodi zbiranja nektarja res zanesljivi in uporabni za globoke ter plitve cvetove in ugotovili, da je metoda s kapilarami bolj zanesljiva, ampak z manjšimi omejitvami pri plitvih cvetovih.

• Title: Analysis of sugars, amino acids, and phenolic compounds in nectar of selected native melliferous plant species : research data underlying the doctoral dissertation

Abstract

In this study, we investigated the nectar of twelve native melliferous plant species. We focused on the quantity of secreted nectar and its composition, particularly sugars, amino acids, and phenolic compounds. We also examined the effect of time of day on nectar as well as the influence of abiotic factors, such as air and soil temperature, soil and air humidity, and UVB radiation. Nectar samples were collected using capillary tubes and by washing flowers in their natural environment in Ljubljana and its surroundings. We evaluated whether both nectar collection methods are reliable and suitable for deep and shallow flowers, and found that the capillary tube method is more reliable, although it has some limitations when used with shallow flowers.
