Sažetak
Fir forests in Croatia spread on the territory of selection forsts on the area of 220136 ha. Silver fir composes pure and mixed stands with spruce and beech. In Croatia, it is spread in the Dinaric region and in mountanious regions between the rivers Sava and Drava. Ecological constitution of Silver fir, despite its narrow ecological valency regarding water and temperature, has indigenously high competitive capacity in comparison with beech and spruce. The aim og this ressearch was to determine the level and variability of laboratory seed germination. Silver fir acorn samples were gathered in autumn 1995. Acorn were manually processed, seed was homogenized and average samples were taken for carrying out this research. The size of average seed samples, the manner of preliminary treatment and germination method were carried out accordng to ISTA methodology. Average values of gemination energy and gemination capacity were low. Average values of germination rate and germinaiton capacity were 14, 4% and 23, 4%, respectively, Average share of empty seed was 58, 4%. Increased share of empty seed directly influences diminished seed germination. The percentage of sick and rottten seed has significant impact on diminished seed gemination and it is 9, 7% on average, for all plots, so the protection of seed from pathogenic fungi has to be intesified.
