Abstract: [Objective and Method]The present experiment was carried out to screen the suitable temperature for Jiashi Muskmelon 1℃,2℃ and 3℃ to study the post-harvesting respiration tate ethylene production,soluble solids content,total sugar content,total acid content,hardness,pulp cell membrane permeability, etc.[Result]The result showed that in the storage process, soluble solids content and total sugar content of Jiashi Muskmelon had dropped slightly, total acid content had dropped obviously in the middle and late storage process; Under 1 ℃,it can maintain hardness of Jiashi Muskmelon,delay the time of respiration peak,reduce respiration rate,last out the lower electrical conductivity,inhibit cell senescence and reduce decay. [Conclusion]Under lower temperature, it is of great importance to devote every effort to maintain the surface of Jiashi Melon.
