摘　　要：以新疆吐鲁番无核白葡萄为实验材料,研究SO2熏蒸对葡萄贮藏中葡萄腐烂率、落粒率和果梗褐变的影响。采用SO2发生器调整熏蒸浓度、熏蒸时间和间隔熏蒸时间,以达到既能够最大程度上抑制葡萄灰霉菌(Botrytis cinerea)孢子的萌发,又能控制SO2残留量在可食用的安全范围内。结果表明,常温下(25℃)采用SO2浓度100mg/L,8min熏蒸时间的处理在体外能够完全抑制葡萄的灰霉菌孢子;0℃条件下,采用200mg/L,8min熏蒸时间的SO2浓度,间隔8d能够明显抑制葡萄中灰霉菌的萌发,同时测得SO2残留的最大值为7.34mg/kg。Taking thompson seedless in Turpan,Xinjiang as experimental materials,the influence of SO 2 fumigation on the decay rate,fall grain rate,stem browing in grape storage period was investigated.The SO 2 generator was used to regulate fumigating concentration,fumigation time,interval fumigation time for not only inhibiting the germination of gray mold spores (Botrytis anerea ),but also controlling the residue of SO 2 within a safe range.The experimental results showed that the gray mold spores of grape could be in-hibited by SO 2 concentration 100 mg/L,for 8 min of fumigation in normal temperature.The germination of gray mold spores could be obviously inhibited by SO 2 concentration 200 mg/L fumigation time of 8 min in 0 ℃ conditions for interval 8 d,at the same time,the maximum value of SO 2 residue was 7.34 mg/kg.
