scarification
Quick Summary
Scarification is a horticultural technique used to break seed dormancy, primarily when a seed has a hard, impermeable seed coat that prevents water and gas exchange, thus inhibiting germination. This process can be achieved through mechanical means, such as scratching or shaking seeds with an abrasive material, or chemically, by dipping seeds in strong acids or organic solvents. Scarification is a crucial step in seed propagation for certain plants, ensuring they can germinate under favorable conditions. Seed propagation itself is a common and cost-effective method for plant reproduction, offering a convenient way to store plants and start them disease-free, though it can lead to genetic variation in cross-pollinated species.12

In chemical scarification, seeds are dipped into strong sulfuric acid, organic solvents such as acetone or alcohol, or even boiling water. In mechanical scarification, they may be shaken with some abrasive material such as sand or be scratched with a knife.
