Abstract
V magistrski nalogi smo v poljskem poskusu ocenili fitoremediacijski potencial dveh sort navadne konoplje, 'Tisze' in 'Future 75'. Izbrali smo tri poskusne lokacije v Celjski kotlini z različno stopnjo onesnaženosti tal s svincem, cinkom in kadmijem: v kraju Medlog (kontrolna lokacija, neonesnažena s Pb in Zn, malo onesnažena s Cd), v kraju Babno (srednje onesnažena lokacija) in v kraju Bukovžlak (najbolj onesnažena lokacija). Pred setvijo smo na vsaki lokaciji odvzeli združene vzorce tal in določili osnovne pedološke parametre (pH, delež organske snovi in rastlinam dostopna hranila) ter vsebnost Pb, Zn in Cd v tleh. Seme smo z Wintersteigerjevo sejalnico posejali junija 2017, na 18 m2 površine. Poskus smo izvajali v štirih ponovitvah, žetev smo opravili oktobra 2017. Izmerili smo biomaso vsakega rastlinskega dela posebej (korenine, seme, socvetja, ločeno stržen in povrhnjica, pri dvospolni sorti 'Tisza' ločen stržen in povrhnjica tudi po spolu) in privzem kovin v rastlinske dele. Najpogosteje smo največjo koncentracijo Pb, Zn in Cd pri obeh sortah izmerili v socvetjih, sledijo korenine in semena, najmanjši privzem Pb, Zn in Cd je pri obeh sortah v stržen in povrhnjico. V eni rastni dobi fitoremediacija z navadno konopljo še ni učinkovita, v več letih pa bi lahko uspešno očistili malo onesnažena tla.

Title:The use of hemp (Cannabis sativa L.) for phytoremediation of soil polluted with heavy metals in Celje valley
Abstract:
In a master's thesis, in a field experiment, we evaluated the phytoremediation potential of two varieties of hemp (Cannabis sativa L.), 'Tisza' and 'Futura 75'. We selected three experimental locations in the Celje valley with different levels of soil contamination with lead, zinc and cadmium: Medlog was control location, not contaminated with Pb and Zn and slightly contaminated with Cd. In Babno, soil was medium contaminated and in Bukovžlak soil was the most contaminated with Pb, Zn and Cd. Before sowing we took soil samples from each location and determinate the basic pedological parameters (pH, organic matter content, nutrients available to plants) and lead, zinc and cadmium content in the soil. The seeds were sown with the Wintersteiger seeder in June 2017 on an 18 m2 large area. The experiment was performed in four replicates. The harvest was carried out in October 2017. We measured the biomass of each plant part separately (roots, seeds, inflorescences, separately pith and epidermis, in the two genders variety 'Tisza' separately pith and epidermis also by gender) and metal uptake by plant. Most often, the highest concentrations of Pb, Zn and Cd in both varieties were measured in inflorescences, followed by roots and seeds. The lowest uptake of Pb, Zn and Cd is in both varieties the pith and epidermis. In one growing season, phytoremediation with hemp (Cannabis sativa L.) is not effective yet, however, in a few years slightly contaminated soil could be successfully cleared with hemp.
