20.500.12556/DKUM-75337 Vpliv predhodne obdelave semena na kalitev tepk (Pyrus communis L.) The effects of Seed Pre-treatments on the Germination of Tepka (Pyrus communis l.) Namen diplomskega dela je bil ugotoviti, kako vplivajo različni načini hladne stratifikacije na kalitev tepk (Pyrus communis L.). Primerjali smo štiri različne načine hladne stratifikacije. Sveže nabrano seme smo hladno stratificirali v hladilniku z različnim časovnim obdobjem (60 in 90 dni), posušeno seme smo stratificirali v zmrzovalniku in sveže nabrano seme smo takoj posejali na prosto. Ugotovili smo, da ima način stratifikacije velik vpliv na kaljivost semen tepk. Semena, ki smo sejali na prosto so značilno bolje kalila v primerjavi z ostalimi obravnavanji. Pri setvi na prosto je vzkalilo 90 % posejanih semen, po 60 dnevni hladni stratifikaciji je vzkalilo 76 % posejanih semen, po 90 dnevni hladni stratifikaciji je vzkalilo 66 % in le 6 % posejanih semen je vzkalilo, če smo jih pred setvijo posušili in stratificirali v zmrzovalniku. The intention of the study was to find out how different methods of stratification influence the germination of Tepka (Pyrus communis L.). Four different cold stratifications were compared. Freshly harvested seeds were cold stratified in the refrigerator at different times (60 within 90 days), dried seeds were stratified in the freezer, and freshly harvested seeds were immediately set free. We have found that the stratification method has a great influence on the germination of bud seeds. The seeds sowed outdoors, germinated significantly better than the ones which underwent the other treatments. Outside sowing resulted in a germination of 90% of sown seed, after 60 days of cold stratification 76% of sown seed germinated, after 90 days of cold stratification 66% of seeds germinated and only 6% of the sown seeds germinated, provided they were pre-sown, dried and stratified in a freezer. / Pyrus communis / stratifikacija / generativno razmnoževanje Pyrus communis / stratification / generative reproduction true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-10-17 19:04:33 2019-10-28 10:17:30 2022-08-09 11:12:56 2019-12-10 08:32:54 2019 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:UMQZBI0K VS_Kosi_Valentina_2019.pdf VS_Kosi_Valentina_2019.pdf 1 8A8E71DC6BC04332335D5541A9440A76 55e159793edbc15187b786005b0ce72b87bb48f20dad2dd56c35f77b6bdf19fa 19799b56-7c11-11eb-bb7a-00155d0001ca 20.500.12556/dkum/82cb2017-e572-4e77-aedf-846b52ab706b https://dk.um.si/Dokument.php?lang=slv&id=139158 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
