Respiration characteristics and quality changes in broccoli as affected by high CO₂ treatment was investigated. Broccoli florets were exposed to high CO₂ (≒ 100%) for 0, 3, 6 and 10 h at room temperature (about 26℃) and then stored at room temperature. The respiration and ethylene productions were decreased remarkably by all treatments except control treatment during storage period. Ascorbic acid content in broccolis florets exposed to high CO₂ was decreased rapidly compared to that in control treatment. After 2 days of storage, yellowing appeared rapidly in the control and in the 3 h high CO₂ treatments.
