Abstract
Maslačak (Taraxacum officinale Weber) je samonikla biljna vrsta sjeverne polutke. Zbog visoke sposobnosti akumulacije kemijskih elemenata, ispunjava sve uvjete za ispitivanje utjecaja zagađenja te se smatra dobrim bioindikatorom. U ovom radu opisano je istraživanje utjecaja poljoprivrednog zagađenja na biokemijske parametre maslačka što uključuje koncentraciju proteina, klorofila i karotenoida, sadržaj askorbinske kiseline i ukupnih topivih polifenola. Povećana koncentracija proteina u uzorcima prikupljenim na zagađenim lokacijama bila je popraćena smanjenjem ukupnih topivih polifenola i askorbinske kiseline te koncentracije karotenoida i klorofila. Nadalje, došlo je do povećanja ukupne antioksidativne aktivnosti kod uzoraka prikupljenih na zagađenim lokacijama. Metode analize glavnih komponenata i infracrvene spektroskopije Fourierovim transformacijama (FTIR) potvrdile su razlike rezultata dobivenih biokemijskim analizama. To ukazuje da su poljoprivredni zagađivači negativno utjecali na produkciju sekundarnih metabolita unatoč dobrom fiziološkom odgovoru te je maslačak pogodna biljna vrsta za ispitivanje utjecaja poljoprivrednog zagađenja i abiotičkog stresa.
Abstract (english)
Dandelion (Taraxacum officinale Weber) is a wild plant species of the northern hemisphere. Due to its high ability to accumulate chemical elements, it is a good species for the investigation of the impact of pollution and is considered a good bioindicator. This paper describes the impact of agricultural pollution on the biochemical parameters of dandelion, which include the concentration of proteins, chlorophyll and carotenoids, the content of ascorbic acid and total soluble polyphenolics. The increased protein concentration in samples collected at contaminated areas was accompanied by a decrease in total soluble polyphenolics, ascorbic acid, carotenoid and chlorophyll concentrations. Furthermore, there was a significant increase in total antioxidant activity in samples collected at contaminated sites. The principal component analysis and Fourier transform infrared spectroscopy (FT-IR) confirmed the differences in the results obtained by biochemical analyses. This indicates that agricultural pollutants have negatively affected the production of secondary metabolites despite the good physiological condition of the plants and that a dandelion is a suitable plant species for investigation of the impact of agricultural pollution and abiotic stress.
