Abstract: The respiration rate,storage quality,lignin and total phenol contents of Annona squamosa L.(AP cultivar)storaged on different temperatures(4 and 25 ℃)were investigated. Cell structure of Annona squamosa L. before and after storage was observed and analyzed. The results showed that the firmness decreased rapidly,the weight loss rate increased obviously,and the soluble solids and soluble protein content decreased significantly at 25 ℃. However,the firmness decreased slowly at 4 ℃,and the weight loss rate was only 5.21% on the 14th day,the soluble solids and soluble protein content increased first and then decreased. Many pores on the cell surface of the fruit were observed at both temperatures,lignin granules were deposited along the inside of the cell wall land an entirely lignified cell has been formed. The lignin content increased during different storage temperatures,but the lignin content at 25 ℃ increased by 44.47% on the fifth day,while just increased by 30.48% at 4 ℃. The total phenolic content increased first and then decreased at 25 ℃,while initial increased,then declined and increased again at 4 ℃. The respiration rate at 25 ℃ achieved a climacteric peak on the second day,reached by 600.23 mg/kg·h,however,the storage at 4 ℃ could effectively inhibit the respiratory rate of the fruit. Conclusion:Low temperature storage can significantly inhibit the respiratory intensity of Annona squamosa L. and delay the lignification process of fruit cell,which is more conducive to retain of postharvest quality of the fruit.
