摘要/Abstract

摘要：

以夏橙、纽荷尔脐橙和椪柑等柑橘类果实为试验材料，使用次氯酸钠和二氯异氰尿酸钠（DCCNa）进行浸果处理，测定果实腐烂率、失重率、可溶性固形物和可滴定酸含量，统计果面微生物变化并通过接种试验观察不同消毒剂对果实采后病害的防治效果，探究DCCNa对柑橘采后预处理的广谱消毒效果。结果表明，与对照相比，DCCNa处理后，夏橙、纽荷尔脐橙、椪柑果实腐烂率分别降低8.70%、5.36%和7.67%；纽荷尔脐橙与椪柑果面微生物减少68.09%和52.49%，接种后青霉病与酸腐病病斑直径分别降低17.47%和11.36%，不同消毒剂处理对果实可溶性固形物与可滴定酸含量变化均无明显影响。综上，DCCNa能在保持柑橘品质的同时显著降低采后腐烂率，控制果实采后病害，具有柑橘采后预处理广谱杀菌应用潜力。

Abstract:

‘Valencia’oranges，‘Newhall’navel oranges，and‘Ponkan’mandarins were used as experimental materials and treated with sodium hypochlorite and sodium dichloroisocyanurate（DCCNa）by immersion. The fruit decay rate，weight loss rate，soluble solids content，and titratable acid content were measured. Changes in microbial populations on the fruit surface were recorded，and inoculation experiments were conducted to evaluate the efficacy of different disinfectants against postharvest diseases. The results showed that DCCNa treatment significantly reduced the fruit decay rates by 8.70%，5.36%，and 7.67% in‘Valencia’oranges，‘Newhall’navel oranges，and‘Ponkan’mandarins，respectively，compared to the control. The microbial populations on the surface of‘Newhall’navel oranges and‘Ponkan’mandarins decreased by 68.09% and 52.49%，respectively. After inoculation，the lesion diameters of blue mold and sour rot were reduced by 17.47% and 11.36%，respectively. Treatments with different disinfectants had no significant effects on the soluble solids content or titratable acid content of the fruits. In summary，DCCNa can significantly reduce the postharvest decay rate of citrus fruits while maintaining their quality，inhibit the occurrence of postharvest diseases，demonstrating great potential as a broad-spectrum disinfectant for the postharvest pretreatment of citrus.
