We investigated the changes of qualities and chemical contents in garland chrysanthemum (chrysanthemum coronarium L. var. spatiosum Bailey.) during storage, and among difference of cultivate varieties and cultivate seasons of same varieties. 1) The apparent quality of garland chrysanthemum kept after 7 days when stored at 10 degrees C. Decreasing rate of carotene content were comparative suppressive during storage at 10 degrees C. But the ascorbic acid content lost by 28.9% after 3 days and by 50% after 5 days. 2) The highest carotene content in 12 cultivate varieties was 4,800 mu-g/100 g f.w. and the lowest was 2,700 mu-g/100 g f.w. But the total ascorbic acid content were little difference among 12 cultivate varieties. 3) The carotene content were closely among different cultivate seasons of same cultivate varieties. The highest total ascorbic acid content was 34 mg/100 g f.w. and the lowest was 17 mg/100 g f.w. High temperature condition during summer season suppressed the increasing of the ascorbic acid content in garland chrysanthemum. 4) The garland chrysanthemum which were bought from shops were lower carotene and the total ascorbic acid content than just harvesting. Two component contents and the appearance quality were decreasing through marketing
