%X <p>Needle fascicles of Scots pine (<em>Pinus sylvestris</em> L.) were rooted in a standard Jacobsen’s germination apparatus. The apparatus was found to be suitable for rooting at least on laboratory scale. The best rooting substrate was living <em>Sphangnum</em>, which remained sufficiently moist in the germination containers throughout the experiments. In a comparison of various growth substrate treatments, the best result was obtained with a combination of IAA (100 mg/l) and thiamine (5 mg/l). The rooting percentage using these growth substances with <em>Sphagnum</em> as the rooting medium was in the first experiment 30 and in the second 48.</p>
