Hypericum adenotrichum Spach. (Hypericaceae, Clusiaceae) is an endemic species to Turkey, which is one of the commonly used species in pharmacological research. We studied seed germination characteristics. The effects of dry storage (3, 9, 12 month), moist chilling (3, 6, 9, 12 month), scarification (H₂SO₄, sand paper), tap water, hormone (250, 500, 1000 ppm GA₃), different temperature (15/10, 20/10 and 25/15 °C) and light (photoperiod, darkness) treatments on seed germination of H. adenotrichum seeds collected from subalpine belt of Uludağ Mountain were examined. Favourable germination temperature for H. adenotrichum is 20/10 °C and no light is required for the seed germination. Seeds of species have physiological dormancy. GA₃ without any other treatment was not successful enough to break the dormancy status alone. Scarification by sulphuric acid and 1000 ppm GA₃ combination is the most effective way for germination of H. adenotrichum seeds. Germination requirements of H. adenotrichum have not been studied previously and the data obtained could be used in the ex-situ protection of H. adenotrichum.

金丝桃属植物。金丝桃科（Hypericaceae, Clusiaceae）是土耳其的特有种，是药理研究中常用的种之一。我们研究了种子发芽特性。干贮（3、9、12个月）、湿冷（3、6、9、12个月）、松土（H ₂ SO ₄、砂纸）、自来水、激素（250、500、1000 ppm GA）的影响₃ )，研究了不同温度（15/10、20/10 和 25/15 °C）和光照（光周期、黑暗）处理对从 Uludağ 山亚高山带收集的H.adenotrichum种子萌发的影响。腺曲霉的适宜发芽温度是 20/10 °C，种子发芽不需要光照。物种的种子具有生理休眠。没有任何其他治疗的GA ₃不足以成功打破休眠状态。硫酸和 1000 ppm GA ₃组合的松土作用是使腺曲霉种子发芽的最有效方法。以前尚未研究过腺曲霉的萌发要求，获得的数据可用于腺曲霉的异地保护。
