description The evaluation of the diversity of silver fir (<i>Abies alba</i> Mill.) populations and the reproductive traits of the trees are of great importance for the conservation of genetic resources and forest management. Therefore, important reproductive characteristics of <i>A. alba</i> from seven Romanian provenances, considered as different geographical populations, were evaluated. Significant differences between the provenances were observed for the female cones, seed morphology, and germination. Due to the relatively low germination of silver fir seeds, germination tests were conducted to identify treatments that can stimulate the germination capacity. Thus, the seed germination capacity was determined using four different stimulation treatments and the data were compared with those of untreated seeds, designed as the control. Considerable differences were recorded not only depending on the seed provenances, but also regarding the treatments applied to stimulate germination (Atonik biostimulator, scarification, acetone, H<sub>2</sub>SO<sub>4</sub>). The biostimulator seed treatment gave the highest germination percentage, while sulfuric acid caused the lowest germination. The research also revealed that not all the forest seed sources provide high-quality reproductive material. Furthermore, for some of the seed resources, even the germination stimulation treatments did not result in adequate germination. The findings are pertinent and valuable for identifying suitable forest populations as seed sources, as well as for their use in silver fir reforestation programs.
