研究不同温度对采后石榴品种‘净皮甜’果实品质和某些生理指标影响的结果表明:在5℃条件下贮藏的石榴,其果实中可溶性固形物含量、总糖含量和可滴定酸含量可以得到保持,果皮的相对电导率和褐变指数升高速率减慢,果实的呼吸速率和腐烂率下降,抗坏血酸氧化酶(AAO)和多酚氧化酶(PPO)活性受到抑制,过氧化物酶(POD)和过氧化氢酶(CAT)活性保持相对较高水平。贮藏120d的果实品质良好,保鲜效果也较好。
The effects of different temperatures on postharvest pomegranate sweet peel quality and some physiological indexes were studied. The results showed that the pomegranate stored at 5 ℃ contained soluble solids content, total sugar content and titratable acid content The relative electrical conductivity and browning index increased slowly, the respiration rate and decay rate decreased, the activities of ascorbic acid oxidase (AAO) and polyphenol oxidase (PPO) were inhibited, while the peroxidase (POD) and catalase (CAT) activity remained relatively high level. The quality of the fruits stored for 120 days is good and the preservation effect is also good.
