Abstract: The"NO.4Xindan"cucumbers were treated with 33?37?42℃for 24h respectively;then was stored in2℃.The respiration rate,chilling i njury index,membrane electric conductivity,fresh hardness,weight lo ss and malondialehyde(MDA)content,chlorophyll content,titr atable acid(TA)and total soluble solids(TSS)were as-sayed in storage.The results showed that heat treatment could inhibit th e occurrence and development of CI,maintain stability of membrane,retard the increasing of membrane electric conductivity and MDAcontent,an d maintain good quality of cucumber.T he coefficient of correlation of quality and physiological indexes were ana-lyzed for low temperature storage of cucumber.The treatment of 37℃was th e best method of hot treatments for inhibiting cold injury.

Key words: cucumber, heat treatment, chilling injury, physiological change
