20.500.12556/DKUM-64245 VPLIV KISIKOVE PLAZME NA KALIVOST PŠENICE INFLUENCE OF OXGEN PLASMA ON WHEAT GERMINATION Uporaba kisikove plazme v kmetijstvu je nova, alternativna tehnika, posledično je raziskav o vplivih na kalitev in zgodnjo rast rastlin relativno malo, informacije so pogosto nepopolne. V rastni komori smo proučevali vpliv kisikove plazme na parametre kalivosti (delež kalečih semen (Kt), hitrost kalitve (H) in skupno hitrost kalitve (Hs)), morfološke lastnosti kalečih rastlin (število korenin (Rn), dolžino posamezne seminalne korenine (Rd), skupno dolžino koreninskega sistema (Rt) in dolžino plumule (Pd) ter mase rastlin (koreninski sistem in plumula) dveh sort ozimne pšenice 'Apache' in 'Bezostaja1'. Vzorce semen smo s kisikovo plazmo obdelali na štiri različne načine: glow (G) režim pri 200 W, 5 s in 30 s ter afterglow (AG) režim pri 600 W 3 s in 5 s. Za primerjavo smo uporabili s plazmo neobdelano seme in seme izpostavljeno le vakuumu in plinu. Rezultati kažejo, da izbrani sorti različno reagirata na plazemsko obdelavo. Pri sorti 'Apache' je, v primerjavi z neobdelanim semenom, viden pozitiven učinek plazme predvsem po obdelavi semena pri AG režimu za 3 s (H in Hs) ter pri AG režimu za 5 s (Rd, Rt, Rs, Pf, Ps). Pri sorti 'Bezostaya 1' so učinki plazemske obdelave manj izraženi: obdelava ima negativen učinek na parametre kalitve, pozitivni učinki so zabeleženi po obdelavi pri G režimu (Rd in Rt). Glede na rezultate lahko sklenemo, da je učinek plazme na zgodnjo rast in razvoj rastlin v veliki meri odvisen od lastnosti sorte in ne zgolj vrste, kar pa je v literaturi nezadostno raziskano. The use of oxygen plasma in modern agriculture is a new and alternative technique. Studies dealing with the impact of oxygen plasma on seed germination and early plant growth are rare and often contradictory. In this thesis, the influence of oxygen plasma on the following parameters was investigated: parameters related to germination (percentage of germinated seeds (Kt), speed of germination (H), speed of accumulated germination (Hs)) and parameters related to morphological properties (number of roots (Rn), the length of each single root (R), the total length of the root system (R) and length of plumula (Pd)). The experimental work was based on two different common wheat varieties ('Apache' and 'Bezostaya 1'). In terms of oxygen plasma treatment, the wheat seeds were exposed to glow (G) position (energy 200 W, time of exposure 5 and 30s) and afterglow (AG) position (energy 600 W, time of exposure 3 and 5 s). For the control group, un-treated wheat seeds and wheat seeds which were exposed just to vacuum and gas were used. The results show that the oxygen plasma treatment has a significant impact on the varieties. In comparison with the control group, the positive impact of the oxygen plasma treatment on the variety 'Apache' was observed in the AG position at 3 s (H and Hs) and AG position at 5 s (Rd, Rt, Rs, pf, Ps). In the case of the 'Bezostaya 1' wheat variety, the statistical differences are not highly significant, and the oxygen plasma treatment has a negative impact on germination. A positive impact was determined in the G position (Rd and Rt). According to the obtained results, it can be concluded that the effect of plasma on plants' early growth and development largely depends on the characteristics of the variety and not only on the species, which is presently an insufficiently researched area. kisikova plazma pšenica kalitev morfološke lastnosti oxigen plasma wheat germination morphological characteristics true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-09-24 17:41:10 2016-10-11 07:13:10 2022-07-05 03:06:38 2019-07-11 13:55:15 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:DCWALUFR VS_Vajsman_Ana_2016.pdf VS_Vajsman_Ana_2016.pdf 1 841BFAA039B6F44B59F97D33B019ABBE f0eb26f03c85fa82cc245fe24ca625ab3afb6641b1563c792774ed61f4c2af92 af3b5e02-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=106739 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
