Vpliv feritnih nanodelcev na rast rdeče ptujske čebule : diplomsko delo

Košir, Tjaša (author), Vogel-Mikuš, Katarina (mentor)

V diplomskem delu nas je zanimalo, kako različne koncentracije feritnih nanodelcev vplivajo na dolžinski prirastek korenine, genotoksičnost, oksidativni stres in viabilnost koreninskih celic po 4., 8., in 12. dnevni izpostavljenosti pri rdeči ptujski čebuli. Če zanemarimo meritve oksidativnega stresa, lahko zaključimo, da je vodovodna voda dober gojitveni medij in negativna kontrola strupenosti pri ocenjevanju vpliva feritnih nanodelcev na rdečo ptujsko čebulo. Raztopina 100 mg/L nano-Fe₂O₃ negativno vpliva na rast korenin in je strupena, medtem ko so suspenzije 0,1, 1 in 10 mg/L nano-Fe₂O₃ manj strupene.

• Title: Effects of ferrite nanoparticles on growth in ptuj red onion

Abstract

In the thesis we were interested in how the different concentrations of ferrite nanoparticles affect the length of the root outgrowth, genotoxicity, oxidative stress and viability of the root cells after 4, 8, and 12 days of exposure in Ptuj red onion. If we overlook the oxidative stress measurement, it can be concluded that the tap water is a good growth medium and negative control of toxicity in assessing the impact of ferrite nanoparticles on red ptuj onions. A solution of 100 mg/L nano-Fe₂O₃ negatively influences the growth of roots and is toxic, while the suspensions 0,1, 1 and 10 mg/L nano-Fe₂O₃ are less toxic.
