Abstract:The garlic bulbs (Allium sativum L.) after harvest were stored at low temperature (1 - 5 ℃), ambient temperature and high temperature (35 ℃), and the subsequent effects of storage on physiological and biocheAncal changes were examined. Respiratory rate, protein and vitadrin C contents gradually increased as the storage period of garlic bulbs progressed at ambient temperature, while sugar and dry matter contents decreased markedly after 2 months of storage, and the germs of garlic bulbs began to sprout. Controlled atmosphere storage (O2 2 - 5%, CO2 8 --10%) at low temperature(1 - 5 ℃) obviously inhibited the germination of garlic bulbs which did not sprout after 8 months of storage, and about 95% of garlic bulbs observed were in good condition. The storage at high temperatue in combination with polyethylene packaging also showed a similar effect.
