Abstract

Samonikle užitne rastline so bogat vir bioaktivnih snovi, ki so pomembne za zaščito in pravilno delovanje našega organizma. Veliko bioaktivnih snovi je antioksidantov in zmanjšujejo tveganje za raka, kardiovaskularne in druge kronične bolezni. V magistrski nalogi smo za preučevano rastlino izbrali smrdljivi regrat (Aposeris foetida (L.) Less.), ki je v Sloveniji vedno bolj znana in uporabljana t. i. »divja hrana«. V naši raziskavi smo želeli ugotoviti ali je smrdljivi regrat primeren za kmetijsko pridelavo in ali lokacija izvora semena vpliva na rast in razvoj rastlin. Opravili smo vse vrtnarske postopke od vzgoje sadik do pobiranja pridelka. V laboratoriju smo v rastlinah gojenega smrdljivega regrata izmerili vsebnosti bioaktivnih snovi (klorofil a, klorofil b, neoksantin, violaksantin, zeaksantin, anteraksantin, lutein, α-karoten, β-karoten, α-, γ, δ-tokoferol in fenolne snovi). Smrdljivi regrat smo gojili v treh različnih tehnologijah pridelave: na hidroponu, na tleh v rastlinjaku in na prostem. Pri pridelavi rastlin se je v našem primeru za najboljšo izkazala tehnologija gojenja na hidroponu. Ugotovili smo, da ima tehnologija gojenja velik vpliv na vsebnost bioaktivnih snovi v gojenem smrdljivem regratu, izvor semena pa pri večini bioaktivnih snovi nima vpliva na njihovo vsebnost v rastlinah. Gojeni smrdljivi regrat smo primerjali z rezultati raziskav samoniklega smrdljivega regrata in druge zelenjave. Ugotovili smo, da imajo gojene rastline smrdljivega regrata večje vsebnosti α-tokoferola, neoksantina, violaksantina, anteraksantina, luteina in VAZ in manjše vsebnosti klorofila in β-karotena v primerjavi s samoniklim smrdljivim regratom. Smrdljivi regrat je primeren za kmetijsko pridelavo, s čimer bi bil bogat vir koristnih bioaktivnih snovi dostopen večji populaciji ljudi.

Secondary title: Introduction of odorous pig salad (Aposeris foetida (L.) Less.) to agricultural production
Secondary abstract: Wild edible plants are a rich source of bioactive compounds which are important for the protection of human body. some of them are even vitally important. Most bioactive compounds are antioxidants, which prevent cancer, cardiovascular disease and other cronic diseases. In our study, the odorous pig salad (Aposeris foetida (L.) Less.), a wild edible plant, which is well known in Slovenia was used. The aim of the study was to investigate its growth and response to the agricultural production system, from sowing to seedlings development to harvesting. We made an analysis of phytochemicals (chlorophylls a and b, carotenoids neoxanthin, antheraxanthin, violaxanthin, zeaxanthin, lutein, α-carotene and β-carotene, tocopherols α, δ and γ and phenolic compounds) and compare the results of the cultivated odorous pig salat with the wild odorous pig salat and some other vegetables. Three production systems were used for plant cultivation: the hydroponic floating system, growing plants in soil in greenhouse and outdoors. In our study the hydroponic floating system showed the best results. The agricultural technologies had a significant impact on the content of bioactive compounds in our plants, while the impact of location of seed origin was not significant. In cultivated plants, a higher content of α-tocpherol, neoxanthin, violaxanthin, antheraxanthin, lutein and VAZ was confirmed, while in wild Aposeris foetida (L.) Less. a higher content of chlorophyll and β-carotene was found. To summarize, the odorous pig salat is suitable for agricultural production and is an excellent source of beneficial substances in human diet.
