摘  要:
以盛花期后145 d左右的黄金梨果实为材料,比较了近冰点温度与1.5℃低温对梨果实贮藏及货架期品质的影响,以期找出延长黄金梨贮藏的适宜温度。结果表明,-1~0℃的近冰温在黄金梨贮后100 d和160 d及其出库后20℃的货架期间均能有效地保持果实果柄新鲜度,降低果实腐烂率,延缓硬度、可溶性固形物(SSC)、可滴定酸(TA)和总酚含量下降,减少乙醇和丙二醛(MDA)生成,抑制呼吸强度和乙烯释放,抑制多酚氧化酶(PPO)的活性。比较不同温度与不同贮藏时间效应的结果表明,-1~0℃近冰温贮藏较之1.5℃贮藏黄金梨可以更好的保持其商品品质。因而,黄金梨的贮藏温度以-1~0℃近冰温贮藏为宜。

摘  要:
Whangkeumbae pear picked about 145 days after full blooming was used to investigate the effects of near freezing temperature and 1.5 ℃ low temperature on fruit quality after storage and shelf-life to determinate the appropriate storage temperature for Whangkeumbae pear.The results indicated that-1 ℃~0 ℃ treatment kept fruit petiole fresh,decreased de-cay index,delayed the drop in firmness,soluble solid content and titratable acidity,decreased ethanol production and MDA content,inhibited respiration and ethylene release,decreased the activity of PPO,whether at 100 d and 160 d after storage or shelf-life at 20 ℃ for 7 d.Comparison of the effects of different temperature treatments showed that the effects of-1 ℃~ 0℃ treatment on Whangkeumbae pear quality was better than that of 1.5 ℃ treatment.Thus,-1 ℃~ 0 ℃ was the appropriate temperature for Whangkeumbae pear storage.
