| 摘 要： | 以新疆木纳格葡萄为原料,在CK对照组和3个不同剂量(0.4、1.2和2 kJ/m2)UV-C照射,贮藏于-1 ℃环境中,研究四种处理对木纳格葡萄可溶性固形物、可滴定酸含量呼吸强度、腐烂率落粒率、好果率等采后贮藏品质的影响。结果表明:采用1.2 kJ/m2 UV-C间隔性(15 d)照射的木纳格葡萄,贮藏期结束保持7.7%的低腐烂率,落粒率为12.51%,好果率为86.6%,同时保持较高的可溶性固形物和可滴定酸含量,分别为16.54%和0.37%,更好地保持了果实的品质。

| Abstract: | Xinjiang Munage grape was irradiated with CK control group and three different doses of 0.4, 1.2, 2 kJ/m2 UV-C, which was stored at -1℃.The effects of four treatments on postharvest storage qualities such as soluable solid content, titratable acidity, respiration intensity, decay rate, fruit dropping rate, good fruit rate of Munage grape were studied.The results showed that the 1.2 kJ/m2 UV-C interval (15 d) irradiation of Munage grape at the end of storage period maintained a low decay rate of 7.7%, a fruit dropping rate of 12.51% and good fruit rate of 86.6%, while maintaining a high soluable solid content and titratable acidity, 16.54% and 0.37%, having better fruit quality. |
