The optimum harvest period of nanguo pear was studied in this paper. The results showed that the soluble solids content of fruits was low, their respiration rate was very high and there was a short storage whether ambient temperature or cold storage in early harvest period. The soluble solids content of fruits was increased according to the expand of harvest period and not fit to long storage. The optimum harvest period was around 9 th, Sep. The better index of harvest period was firmness, soluble solids content, index of seed change color.
