Abstract
Abies nordmanniana seedlots, selected from provenances at various altitudes, were investigated. Cutting test showed that the filled seed percentage was relatively high among seedlots originated from the seed-stands of Artvin district in Turkey. Filled seeds percentage varied from 70% to 87% in the four seedlots. The seed of A. nordmanniane from the lower altitude (Ortakoy seedlot, 1600 m asl) showed a greater response to stratification treatment to overcome dormancy than did other seedlots from higher altitudes (Meydancik seedlot, 1950 m; Yayla and Velikoy seedlots, 1800 m). There were significant differences in germination among pre-treatments, seedlots and stratification temperatures. Polystimulin hormones had a large effect on enhancing the germination of all seedlots. Twenty-three days of cold-moist stratification in sand increased the percentage germination and germination energy. Stratification at 9 degrees C was more effective than stratification at 4 degrees C. A combination of polystimulin pre-treatment with 23 days of stratification gave the best results in terms of the percentage germination and germination energy. Germination was obtained in 87% Of filled seeds. which is the highest ratio yet obtained for A. nordmanniana.
