stratification-2 trial. Germinations were observed in the nursery at the 20.0-27.9% soil moisture level in the control and in the stratification-1 trials, but germinations were observed at 44.0-51.9% soil moisture level in the stratification-2 trial. While no germinations were observed in the greenhouse after the 60.0-67.9% soil moisture level in the stratification-2 trial, germinations were observed after the 76.0-83.9% soil moisture level in the control trial and after the 84.0-91.9% soil moisture level in the stratification-1 trial. In the nursery no germinations were observed after the 60.0-67.9% soil moisture level in the stratification-1 and in the stratification-2 trials, but germinations were observed at the 76.0-83.9% soil moisture level in the control trial (Figure 4). ANOVA test results showed that there were no significant differences (p<0.05) between germination percentages according to the sowing environment, pretreatment, soil moisture levels, sowing environment*soil moisture level and pretreatment*soil moisture level interactions (Table 6). Mean germination time – Prosječno vrijeme klijanja While the average germination time was determined as 18 days in the control trial in the greenhouse, it was determined as 10 days in the stratification-1 trial and 9 days in the stratification-2 trial. In the nursery, the mean germination time was determined as 19 days in the control trial, as 25 days in the stratification-1 trial and as 9 days in the stratification-2 trial. It has been determined that the mean germination time in the greenhouse (12 days) was shorter than the mean germination time in the nursery (18 days). In addition, obtained results showed that stratification and sowing time have a positive effect on the mean germination time in the greenhouse. DISCUSSION AND CONCLUSIONS RASPRAVA I ZAKLJUČCI In the germination trials, higher average germination percentages were obtained in the greenhouse compared to the nursery after the control and stratification-2 process, while the average germination percentages obtained after the stratification-1 process were realized at the same rate in both greenhouse and nursery. In many studies in the literature, it is stated that higher germination percentages were obtained in the germination studies performed in maples and in some other species in the greenhouse compared to the germination trials carried out in the nursery (Göktürk et al. 2007; Özana 2019; Erdo&287;an Genç and Üçler 2020a; Erdo&287;an Genç and Üçler 2020b). Therefore, it is possible to state that the sudden environmental factor |
