Scarification is used to achieve what effect on seeds?

• A. Hydration
• B. Stratification
• C. Gestation
• D. Scarification

Answer: (D)

Scarification targets seeds with a hard, protective coat and works by breaking or weakening that coat. When the seed coat is disrupted, water and gases can enter more easily, allowing the seed to hydrate and begin germination. In other words, the purpose is to overcome physical dormancy caused by a tough coat, enabling germination. Hydration happens as a result, while stratification is a different dormancy-breaking method that uses cold exposure, and gestation isn’t a relevant term here.
