20.500.12556/DKUM-16087 VPLIV KLIMATSKIH IN AGROTEHNIČNIH DEJAVNIKOV NA KALITEV IN VZNIK OLJNIH BUČ The effect of climatic and agricultural factors on germination and emergence of oil pumpkins Toplota, svetloba, vlaga in tip tal so ključni dejavniki za kalitev in vznik rastlinic. Z namenom, da bi preverili vpliv teh dejavnikov na kalitev oljnih buč v primerjavi z jedilnimi, sta bila postavljena dva eksperimenta v rastni komori in eden v rastlinjaku. Proučen je vpliv toplotnega režima (12, 14, 16 °C), svetlobe (temno 0 ur, pol svetlo 12 ur ter svetlo 24 ur), vlage (40 % PK in 100 % PK) in tal (glinena ilovica in peščena ilovica) oz. substrat na odstotek živokalečih semen in maso rastlinic. Rezultati kažejo, da bučevkam odgovarjajo topla tla (vsaj 18 °C), kalitev v temi in 100 % PK. Zaradi omejene kalitve pri nižjih temperaturah je obvezno sejati več semen na setveno mesto in kasneje redčiti, substratu pa dodati glinene delce. Pri zasnovi je potrebno upoštevati tudi specifične zahteve vrste semena. Temperature, light, humidity and soil type are key factors for germination and emergence of seedlings. In order to examine the influence of these factors on the germination of oil pumpkins in comparison with garden pumpkins, two experiments were placed in a growth room and one in a greenhouse. The factors examined were the impact of the temperature regime (12, 14, 16°C), light (dark 0, half-light 12 and light 24), moisture (40% field capacity and 100% field capacity (FC)) and soil type (clay loam and sandy loam) and the substrate on the percentage of live seed emergence (PLSE) and seedlings mass, respectively. The results show that cucurbits like warm soil (at least 18°C), germination in darkness and 100% FC. Due to limited germination at lower temperatures it is required to sow more seeds on planting site, thin the plants later on and add clay particles to the substrate. When designing, specific requirements of seed species should also be taken into consideration. oljna buča kalitev vznik klimatski dejavniki oil pumpkin germination emergence temperature true true false Slovenski jezik Angleški jezik Diplomsko delo 2010-09-30 09:15:43 2010-10-15 09:42:36 2022-04-13 07:51:32 2023-12-20 03:16:32 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:4KV7XSMU VS_Mihelic_Matjaz_2010.pdf VS_Mihelic_Matjaz_2010.pdf 1 EC7FA0F5C68664C635D1C40235814F7D d8bc534ff65e9efd055d8fd38f117252d5e3a88476d385e14ea1f8cbebcc5163 995389b1-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/8371ff2a-ddc1-4a04-ae25-f2f040f3ede8 https://dk.um.si/Dokument.php?lang=slv&id=18301 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
