hormone promoted the germination in 8-w pre-chilled seeds and increased the germination percentage. There was a distinctive difference between the germination percentage for the 8-w pre-chilled and non-pre-chilled seeds (Figure 2).
DISCUSSION AND CONCLUSIONS
RASPRAVA I ZAKLJUČCI
The seed cones of Syrian juniper are the largest of any juniper species(Yaltırık, 1988). In present study, the average cone length and diameter was found 22.49, 20.86 mm, respectively. In another study (Sobierajska et. al., 2016), average cone length and cone diameter of J. drupacea for 12 populations was found 20.54 and 19.18 mm, which were relatively similar to our results. The average number of seeds extracted from the cones was 2.2. There wasn’t a statistical difference between the provenances in terms of cone length, diameter and seed number. In other two studies the average seed number was 2.1 (Gültekin et al., 2005) and 2.3 (Gürlevik and Gültekin, 2008).
In this study the average 1000-seed weight was found 44.66 g for three provenances.1000-seed weight generally occurs between 10-90 g depending on the species and provenances (Bonner, 2008). In J. virginiana L. and J.occidentalis
