Ginseng seed stratification (개갑 처리) is an essential process for enhancing seed germination by overcoming dormancy. Ginseng seeds naturally exhibit deep dormancy, requiring specific treatments to break it and improve germination rates. The stratification process typically involves cold treatment at around 2°C for varying periods, with common durations being 30 to 90 days, depending on the seed's physiological state.
Research shows that the most effective stratification periods for Panax ginseng involve treatments of 60 to 90 days, where seeds begin to germinate more significantly compared to shorter durations. For example, seeds treated for 90 days at 2°C showed a germination rate of 14.6%,...
