Materials are divided into three groups by different maturity, with or without stems of the winter jujube, using infrared CO2 analyzer mensurate the respiration rate changes in different parts of winter jujube, while the winter jujube were completely coated with Vaseline(with stems and peel coated) and semi-coated(with peel coated) and untreated. The results show that: the respiration rate of untreated winter jujube with or without stems has a slow upward trend as winter jujube’s maturity increased; The respiration rate of the winter jujube with stems is significant (P <0.05) compared with that of the winter jujube without stems; the proportion of respiration rate of stems of with stem winter jujube is about 40%,that of peel is about 60% ,so the main respiration channel of winter jujube with stems is the peel; the proportion of respiration rate of stems of without stems winter jujube is about 75%,that of peel is about 25%, so the main respiration channel of winter jujube without stems is the stem; as the winter jujube stems falling off, the main respiration channel may transferred from peel to stem.
