Abstract: Using 3 cultivars of wampee (Clausena lansium), i.e. "Large chicken heart", "Small chicken heart" and "Round species" as experimental materials, differences of respiration rate, productive rate of ethylene and quality of wampee fruits as well as their changes during storage at room temperature (28±2℃) were investigated,. The results showed that the rate of edible fruit, contents of total soluble solids and Vc decreased significantly, and rate of weight loss and contents of soluble pectin and protopectin increased significantly. Content of titratable acidity decreased rapidly within 2 days and increased 2 days later. Respiration rate raised remarkably after 4 days of storage, but no respiration climax was observed, which suggested that wampee belonged to the non-respiration climacteric fruit. Respiration rate of "Large chicken heart" was much higher than that of "Small chicken heart" and "Round species" in the late period of storage. Ethylene productive rate of wampee fruits increased within 4 days of storage, and then "Large chicken heart" and "Small chicken heart" decreased apparently while "Round species" continued increasing.
