| 目的 为了研究不同保鲜剂组合对无核白葡萄采后贮藏品质的影响。方法 以无核白葡萄为实验材料，选取CT2 4包+CT5 1包、CT2 2包+CT5 1包、CT2 2包+CT5 1包+O3 10.7 mg/L 1h和CT2 2包+CT5 1包+ClO2 3 mg/L 1h等4种保鲜剂组合处理葡萄，每隔15 d测定呼吸强度、腐烂率、可溶性固形物、可滴定酸、硬度、还原糖、多酚氧化酶活性和抗坏血酸酶活性等各项指标。结果 在温度(-1±1)℃的贮藏条件下，在4种处理中，随着贮藏时间的延长，采用CT2 2包+CT5 1包处理后效果较好，在贮藏75 d后，CT2 2包+CT5 1包+O3 10.7 mg/L 1 h处理组果实的呼吸强度为4.16 mg/(kg•h)，腐烂率为30.3%，可溶性固形物质量分数为20.83%，可滴定酸质量分数为0.86%，硬度为4.16 kg/cm2，还原糖质量分数为15.62%，多酚氧化酶活性为0.41 U/(min•g)，抗坏血酸酶活性为18.42 U/(min•g)，明显优于其他3种处理。结论 CT2 2包+CT5 1包+O3 10.7mg/L 1h处理能够较好地延长葡萄的贮藏期，维持果实的贮藏品质。 |

| The work aims to study the effect of different preservative combinations on the quality of post-harvest storage of Thompson Seedless Grape. This experiment used Thompson Seedless Grape as test materials and selected four preservative combinations including CT2 (4 packs) +CT5 (1 pack), CT2 (2 packs) +CT5 (1 pack), CT2 (2 packs) +CT5 (1 pack) +O3 (10.7 mg/L) 1h and CT2 (2 packs) +CT5 (1 pack) +ClO2 (3 mg/L) 1h to treat the grapes. The respiratory intensity, rotting rate, soluble solid content, titratable acid, hardness, reducing sugar, polyphenol oxidase activity, ascorbate and peroxidase activity and other indicators were measured every 15 days. Under the storage conditions of (-1±1)℃, in the 4 treatments, with the extension of storage time, the effect was better after the treatment with CT2 (2 packs) +CT5 (1 pack). After 75 days of storage, in the group of CT2 (2 packs) +CT5 (1 pack) +O3 (10.7 mg/L) 1h treatment, the fruit's respiration intensity was 4.16 mg/(kg•h), the rotting rate was 30.3%, the soluble solid mass fraction was 20.83%, the titratable acid mass fraction was 0.86%, the hardness was 4.16 kg/cm2, reducing sugar mass fraction was 15.62%, PPO activity was 0.41 U/(min•g), and APX activity was 18.42 U/ (min•g), obviously better than the other three treatments. Therefore, the CT2 (2 packs) +CT5 (1 pack) +O3 (10.7 mg/L) 1h treatment can better prolong the storage period of the grapes and maintain the quality of the fruit storage. |
