Cupressus lusitanica Mill. is a multipurpose tree species with a high potential for wood production in Brazil. The main objective was to evaluate methods to dormancy break to promote seed germinationin C. lusitanica. The following treatments were used: T1 (intact seeds); T2 (soaking in water for 24 hours); T3 (soaking in water for 36 hours); T4 (stratification on 4 °C for 30 days); T5 (immersion in water for 8 hours + stratification on 4 °C for 30 days); T6 (immersion in water for 8 hours + stratification on 4 °C for 20 days); T7 (immersion for 12 hours + stratification on 4 °C for 20 days); T8 (soaking in hot water at 80C for 5 minutes); T9 (sulfuric acid soaking for 5 minutes). It was evaluated the percentage and germination speed (IVG). The resultsweresubmitted to ANOVA andmeanswere comparedusingthe Skott-Knott. The treatments T5, T2 and T7 showedhighergermination, and T7 higherspeedofgermination, thesecanberecommended for overcomingseeddormancyof C. lusitanica.
