Abstract: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.

Title:The effect of climatic and agricultural factors on germination and emergence of oil pumpkins
Abstract: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.
