This experiment studied physiological and bio-chemical changes of Pingguo pear durint storage period.The result showed that low temperature obviously delayed many changes during maturity.Its respiration intensity was very low,within 210 mg CO2/kgh and only 23 mg CO2/kgh during later storage period.The ethylene production of Pingguo pear was extremely low,less than 0.5 L/kgh.Ethylene acted importantly on Pingguo pear after ripening,affected changes of many substances.Pingguo pear could preserve its hardness and vitamin C content during storage time.
