20.500.12556/DKUM-86719 Vpliv elektrolizirane oksidativne vode na sprejem mineralnih hranil pri visečih in pokončnih pelargonijah magistrsko delo Electrolyzed oxidative wateron the uptake of mineral nutrients in hanging and standing geraniums Pelargonije (Pelargonium) so bogato cvetoče, živobarvne rastline, ki ob primerni negi cvetijo neprekinjeno od maja do prvih jesenskih zmrzali. Ena izmed alternativ za namakanje rastlin je uporaba elektrolizirane oksidativne vode (EOW). Namen raziskave je bil preučiti vpliv EOW in termina vzorčenja na vsebnost makro‒hranilnih (K, Ca in Mg) in mikro‒hranilnih elementov (Zn, Cu, Fe in Mn) v listih dveh sort pelargonij. V ta namen smo rastline zalivali z vodo (kontrola), 0,1 % in 0,2 % raztopino EOW in vzorčili 63 dni od sajenja potaknjencev ter po 5 tednih rasti. Minerale smo v raztopinah po kislinskem razklopu vzorcev določili z atomsko absorpcijsko in emisijsko spektrometrijo. Zalivanje z 0,1 % in 0,2 % EOW je pozitivno vplivalo na privzem K in Ca pri obeh sortah pelargonij. V drugem terminu vzorčenja smo pozitiven vpliv 0,2 % EOW zaznali tudi pri privzemu Cu pri obeh sortah in Zn pri pokončnih pelargonijah, medtem ko na privzem Mn EOW ni imela vpliva pri nobeni sorti pelargonij. Negativen vpliv obeh koncentracij EOW se je pokazal pri privzemu Fe pri obeh sortah pelargonij v drugem terminu vzorčenja in Mg v prvem terminu vzorčenja. EOW bi lahko bila dobra alternativa za zalivanje potaknjencev pelargonij, ki jih vzgajamo z namenom prodaje sadik na tržišču. Pelargoniums (Pelargonium) are richly flowering, brightly coloured plants that bloom continuously from May until the first autumn frost, provided they are given the proper care. One of the alternatives for watering plants is the use of electrolyzed oxidative water (EOW). The aim of the research was to examine the impact of EOW and the sampling date on the content of macronutrients (K, Ca and Mg) and micronutrients (Zn, Cu, Fe and Mn) in the leaves of two pelargonium cultivars. For this purpose, the plants were watered with water (control), 0,1 % and 0,2 % EOW solution and sampled 63 days after planting the cuttings and after 5 weeks of growth. The minerals in the solutions were determined via atomic absorption and emission spectrometry, after the acid decomposition of the samples. Watering with 0,1 % and 0,2 % EOW had a positive effect on K and Ca uptake in both pelargonium cultivars. During the second sampling period, a positive impact of 0,2% EOW was observed in the uptake of Cu in both varieties and Zn in upright pelargoniums. However, EOW did not affect the uptake of Mn in any pelargonium variety. Conversely, both concentrations of EOW exhibited a negative influence on the uptake of Fe in both pelargonium varieties during the second sampling period, as well as on Mg during the first sampling period. EOW could be a good alternative for watering pelargonium cuttings intended for sale as seedlings on the market. pelargonije hranila elektrolizirana voda substrat korelacija pelargonium nutrient electrolyzed oxidative water substrat correlation true true false A.
