Abstract: To investigate the changes in allicin content in various organs of garlic （Allium sativum L.） during the seedling, germination, differentiation, and expansion stages under different cultivation methods,two types of garlic were used as materials for soil and hydroponic experiments, respectively,and the HPLC method was used to determine the allicin content in roots, bulbs, and leaves of garlic plants under two different cultivation methods. The results showed that during the emergence, germination, and differentiation stages, the allicin content in the roots of both garlic plants under soil cultivation showed a trend of first decreasing and then increasing, while under hydroponic cultivation, the allicin content in the roots of both garlic plants remained basically unchanged; under soil cultivation, the allicin content in the bulbs of two garlic plants showed a trend of first decreasing and then increasing, while under hydroponic cultivation, the allicin content in the bulbs of two garlic plants showed a trend of first increasing, then decreasing, and then increasing; under soil cultivation, the allicin content in the leaves of both garlic plants showed a decreasing trend, while under hydroponic cultivation, the allicin content in the leaves of both garlic plants showed an increasing trend. In summary, there were differences in the changes of allicin content in various organs of garlic plants at different growth stages under two cultivation methods,during the germination and differentiation stages, the allicin content in different tissues of two types of garlic grown in hydroponics was higher than that grown in soil,and during the emergence, germination, and differentiation stages, the allicin content in the leaves of both garlic plants was higher than that in other organs under hydroponic conditions.
