Scarification
The process of scratching or softening the hard seed coat to allow water and gases to penetrate, which triggers germination.
Также говорят: seed coat treatment, mechanical abrasion, nicking
Scarification is essential for seeds with dormant, impermeable coats that prevent moisture uptake. By creating small openings in the seed coat, growers mimic natural weathering processes, significantly increasing the germination rate.
Methods include mechanical abrasion (using sandpaper or filing) or chemical treatment (soaking in mild acids). The choice depends on seed size and durability.
Common mistakes include aggressive mechanical action that reaches the internal embryo or improper chemical exposure times. Always perform a test batch to determine the appropriate intensity for specific seed lots.
