20.500.12556/DKUM-13706 VEGETATIVNO RAZMNOŽEVANJE TOPOLOV (Populus spp.) S POTAKNJENCI VEGETATIVE REPRODUCTION OF POPLAR SPECIES (Populus spp.) WITH CUTTINGS Raziskava je bila opravljena na treh vrstah topolov: črnem topolu (Populus nigra L.), belem topolu (Populus alba L.) in trepetliki (Populus tremula L.). Namen diplomskega dela je bil proučiti ukoreninjenje potaknjencev topolov glede na okolje koreninjenja, termin potikanja in vrsto uporabljenega substrata. Zeleni in pololeseneli potaknjenci so bili večinoma nabrani v okolici celjske regije in Žalca. Koreninjeni so bili v šestih terminih (od junija do septembra) v okolju meglenja in neposrednega prekrivanja s polietilensko folijo v industrijskem in lastnem substratu. Uspeh koreninjenja je bil odvisen od okolja koreninjenja, termina in substrata. Kot najprimernejši čas za razmnoževanje črnega in belega topola so se pokazali zgodnejši poletni termini. Pri črnem topolu smo v drugem terminu v okolju neposrednega prekrivanja s polietilensko folijo z uporabo Klasmannovega — industrijskega substrata dosegli 100-odstotno ukoreninjenost, pri belem topolu pa v prvem terminu 85,4-odstotno ukoreninjenost potaknjencev v enakem substratu in okolju. Trepetlika se je najbolje ukoreninila v prvem terminu v okolju meglenja pri uporabi lastnega substrata. The research was done on three species of Populus L.: black poplar (Populus nigra L.), white poplar (Populus alba L.) and aspen (Populus tremula L.). The purpose of diploma work was to investigate the rooting of the cuttings according to the enviroment of rooting, the term of cutting and a type of substrate. Green and half wooden cuttings were mostly picked up in the region of Celje and Žalec. They were rooted in sixth terms (from june to september) in the enviroment of mist and directly covered with polyethylene film, cultured in industrial and own made substrate. The success of rootting was dependent of enviromental rooting, term and substrate. As the most appropiate time of reproduction for black and white poplar were being shown the early summer terms. At black poplar we reached in second term, directly covered with polyethylene film and the use of Klasmann – industrial substrate, 100% rooted cuttings, and at white poplar we reached in the first term 85,4% percentage rooted cuttings in the same substrate and enviroment. Aspen was the most well rooted in the first term under the enviroment of mist and the use of own made substrate.
