Rubus ODORATUS

Sowing and germination

seeds are sown in autumn or spring. When sowing in spring, a two-stage stratification is required: 3 months warm at +20+30°C, then at least 3 months cold at +2+5°C; seed germination improves under the influence of preliminary scarification, treatment with concentrated sulfuric acid for 20-60 minutes or 1% sodium hypochlorite solution for 7 days. Seed germination is low.
