摘要：This paper presents results of experiments lasting over 3 years (2006 - 2008) to determine the best stratification cnditions for overcoming dormancy in the seeds of the wayfaring tree (Viburnum lantana), European euonymus (Euonymus europaeus) and European bladdernut (Staphylea pinnata). The experiments compared the effects of different pre-sowing treatments (stratification) on seed germination, specifically different combinations of duration and temperature of warm (10, 15, 20 or 30°C depending on species) and cold (4°C) stratification periods. Total period of stratification renged from 3 to 6.5 months. The effect of seed soaking in detergent (in 10 ml/l solution for 3 days at 4°C) and removing of the fleshy pulp (aril) before stratification on germination of seedling emergence of Euonymus seeds were also investigated. Germination of stratified seeds sown in spring was compared to field emergence of non-stratified seeds or fruits sown immediately after summer or autumn collection.
