To evaluated the effect of low temperature storage on quality of fresh shoot of Sedum sermentosum, weight loss, Hunter L, a and b value, chlorophyll, water content, and general appearance were investigated during storage at 20, 10, and $5^{circ}C$. Just after harvesting, fresh shoots ($10{pm}2cm$ length) were stored with wrap film (linear LDPE)-packaged condition using the Styrofoam dish ($20{ imes}10cm$, which 40 fresh shoots per dish). The fresh weight of 40 shoots was gradually decreased according to days after storage and higher storage temperature. The weight loss of fresh shoots showed significant difference (8.7-25.3%) between just before storage and 10 days after storage, and the degree of weight loss was more severer in higher storage temperature. Wanju local strain showed the lowest weight loss, and the most severe case was Pohang local strain. SPAD value related to chlorophyll content was rapidly decreased after 4 and 6 days at 20 and $10^{circ}C$ storage, respectively. It was slowly decreased according to days after storage at $5^{circ}C$. Yellowish color in bottom leaves of shoot appeared after 4, 6 and 8 days at 20, 10, and $5^{circ}C$ storages, respectively. Hunter L and a values were gradually increased after storage, and it showed significant difference between just before storage and 10 days after storage. The total rate of discoloration over 50% or decay shoot was largely increased as higher temperature. It was significantly correlated to the water content of fresh shoot among local strains $(P{leq}0.01)$. The freshness of shoot after storage was maintained in order of Wanji, Gunsan, Wando and Pohang local strain. The results indicated that the freshness was maintained for 8 days after $5^{circ}C$ storage, when the fresh shoot was stored with wrap film-packaged condition.
