Vpliv fotooksidantov na zmanjšanje rasti in nastanek listnih poškodb pri plazeči detelji (Trifolium repens L.) : diplomska naloga = Impact of photooxidants on the growth reduction and appearance of leaf injuries of white clover (Trifolium repens L.) : graduation thesisPačnik, LeopoldaVse večje koncentracije fotooksidantov, posebej ozona so glavni vzrok za raziskavo o njegovem vplivu na rast in razvoj izbrabih vrst kmetijskih rastlin. Pri tem smo uporabili metodologijo ... mednarodnega programa IPC Crops. Kot mesta raziskave smo izbrali naslednji lokaciji, kjer so bile na voljo meritve ozona in podnebnih parametrov: Iskrba pri Kočevju, kot primer neonesnaženega ruralnega okolja in Ljubljano, kot mestno okolje. Zastopanost ozona smo na vseh lokacijah spremljali na podlagi pojavljanja tipičnih poškodb - listnih nekroz na izbranih sortah indikatorskih kmetijskih (fižol, sončnica, plazeča detelja) rastlin in na nekaterih, v bližini rastočih, samoniklih vrstah plevelov in travniških rastlin. Odziv izbranih indikatorskih rastlin na učinke ozona smo ugotavljali na osnovi pojavljanja tipičnih poškodb, meritev biomase in nekaterih fizioloških in biokemičnih parametrov, upoštevajoč navodila IPC Crops programa. Rezultate opazovanja pojavljanja listnih poškodb plazeče detelje smo poskusili prikazati v odvisnosti od ozona. V poskus je bilo vključeno tretiranje plazeče detelje s spojino EDU (etilendiurea), ki naj bi ščitila rastline pred ozonom. Raziskava je potrdila zelo velike koncentracije ozona, ter njegov škodljiv vpliv na rast in razvoj plazeče detelje, ter nekaterih drugih rastlin. EDU spojina ni pokazala popolne zaščite rastlin plazeče detelje.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
