Seed germination and seedling emergence in Hippophaë rhamnoides L.
Dendrobiology 2010, vol. 63: 53-58
Abstract: In contrast to earlier reports, in this study Seabuckthorn seeds collected from ripe fruits proved to be non-dormant. Most of them germinated quickly at high temperatures (e.g. cyclically alternating temperatures of 20~30°C daily for 16 and 8 hours, respectively). At lower temperatures (3~20°C), seeds did not germinate or germinatedslowly, but stratification at 3°C for 4-6 weeks increasedtheir germination rate to 90-100% within 2-3 weeks. Seedling emergence in the open nursery proved to be risky, even after 6-8 weeks of seed stratification, so spring sowing in the greenhouse (or plastic tunnel) is recommended.
