一、愈伤水果和蔬菜在采收过程中很难避免机械损伤 ,愈伤是伤口处周皮细胞的木栓化过程 ,一般需要高温多湿的环境条件。例如 :马铃薯采后在１８．５℃下保持２～３天 ,然后放在７．５～１０℃和９０%～９５%的相对湿度下１０～１２天可完成愈伤。愈伤的马铃薯比未愈伤马铃薯的 First, callus fruits and vegetables in the harvest process is difficult to avoid mechanical damage, callus is wound at the periosteal cells of the cork process, generally require high temperature and humidity of the environmental conditions. For example, the potato is preserved at 18.5 ° C for 2 to 3 days after harvest, and then callus is completed within 10-12 days at 7.5-10 ° C and 90-95% relative humidity. Potato callus is harder than callus
