Fresh-keeping Technology of Peach, Plum and Apricot during Storage

It is because of the hard core in the fruit that there is a double S-shaped growth curve during growth. Peach, plum and apricot fruits have high respiratory intensity; they all have respiratory peaks, so they all belong to respiratory jump fruits, which determines that they have basically similar storage and transportation fresh-keeping measures. However, with different tree species and varieties, the storage and transportation techniques used are different. Peaches and plums are general.
