stratification-2 trial. In the nursery, the highest germination percentages were obtained as 23% at the 57.0-62.9% relative air humudity level in the stratification-1 trial, as 20% at the 63.0-68.9% relative air humidity level in the control trial and as 8.5% at the 75.0-80.9% relative air humudity level in the stratification-2 trial. While no germinations were observed after the 87.0-92.9% air humidity level in the control and in stratification-2 trials in the greenhouse, germinations were observed after the relative air humidity level of 87.0-92.9% in the stratification-1 trial. In the stratification-2 trial, no germination was observed up to the 69.0-74.9% relative air humidity level both in the greenhouse and in the nursery, but germinations were observed in the greenhouse at the 39.0-44.9% relative air humidty level in the control trial and at the 51.0-56.9% relative air humidty level in the stratification 1 trial. No germination was observed in the nursery up to the 45.0-50.9% relative air humidity level in the control and in the stratification-1 trial. Moreover, no germination was observed in the nursery after the 81.0-86.9% relative air humidty level in the stratification-1 trial. However, germinations were observed in the nursery after the 81.0-86.9% relative air humidty level in the control and in the stratification-2 trials (Figure 3). ANOVA test results showed that there were no significant differences (p<0.05) between germination percentages according to the relative air humidity levels, sowing environment*relative air humidity and pretreatment*relative air humidity interactions. On the other hand, significant differences were found between germination percentages according to the pretreatments (Table 5). Soil moisture and germination percentage – Vlažnost tla i postotak klijavosti The highest germination percentages in the greenhouse were obtained as 34.7% at the 60.0-67.9% soil moisture level in the control trial, as 12.5% at the 44.0-51.9% soil moisture level in the stratification-1 trial and as 15.5% at the 36.0-43.9% soil moisture level in the stratification-2 trial. In the nursery, the highest germination percentages were obtained as 29.3% at the 36.0-43.9% soil moisture level in the control trial, as 26.5% at the 20.0-27.9% soil moisture level in the stratification-1 trial and as 8% at the 60.0-67.9% soil moisture level in the stratification-2 trial. No germinations were observed in the greenhouse until the soil moisture reached to the 36.0-43.9% level in the control trial. However, germinations were observed in the greenhouse at the 20.0-27.9% soil moisture level in the stratification-1 trial and at the 28.0-35.9% soil moisture level in the |
