Sažetak
European beech is the most common tree species of forest vegetation in Croatia. In established experimental plots within seed stands of Forest administrations Ogulin, Karlovac, Bjelovar and Požega in 2016, beechnuts were collected from five selected trees in each plot. Nets for collecting the beechnuts were placed at 1 m above ground covering whole projection area of their crowns. Seeds were collected four times in the period from September to November. The goal of this study was to analyse beechnuts quality and quantity due to different seed stands. Seed analyses were performed in the Laboratory for Seed Testing of the Croatian Forest Research Institute. 1000 seed weight (TSW), moisture content and viability were assessed. All analyses were performed with regard to collection time. ISTA methods were used for testing seed quality. Statistical analyses were generated using SAS/STAT software. The results of descriptive statistics showed that the largest mean beechnut yield was in population Bjelovar (97.62 kg), while the smallest in the population Ogulin (28.42 kg). The average TSW was the highest in population Ogulin (283.6 g) and the lowest in population Požega (192.2 g). Moisture content of freshly collected beechnuts of last beechnuts collecting varied from 17 to 35 %. Viability was tested by biochemical test - the Topographical Tetrazolium Test and the best result was in population Ogulin (72%). This work has been fully supported-supported in part by Croatian Science Foundation under the project (8131).
