1982年,八个Euvitis葡萄品系(2个栽培种和6个选择的品系)在0°±0.5℃、无SO_2发生器条件下分别贮藏4、6、7和8周;而在有SO_2发生器的,以聚乙烯薄膜为衬里的起皱迭嵌的5.7升卡纸板船运箱里,分别贮藏4、8、12,16和20周.从浆果外观看,无SO_2贮藏4周后的葡萄比SO_2贮藏8周后的葡萄要差.用SO_2处理贮藏16周后,8个品系中有4个其外观仍与贮藏前具有同一等级.总的来说,无SO_2处理条件下浆果风味可以保留7周多;而用SO_2处理的可以保留12周多.无SO_2~-处理的,在贮藏8周期间,8个品系中有6个烂果达23～60%;相比之下,有SO_2处理,贮藏16周烂果仅3%或更少.由SO_2引起的药害为0～59%.但引起浆果风味及外观变差其程度上超出保鲜要求的仅有两例.在SO_2处理条件下,8个品系贮藏12周后,浆果还很好;据评定Suffold Red品系较为突出,加SO_2贮藏20周后,浆果外观及浆果风味与贮藏前一样,烂果仅3.5%.
In 1982, eight Euvitis grape lines (2 cultivars and 6 selected lines) were stored at 0 ° ± 0.5 ° C for 4, 6, 7 and 8 weeks without SO 2 generator respectively; whereas in the presence of SO 2 generator The polyethylene film-lined crumpled 5.7-liter cardboard shipping boxes were stored for 4, 8, 12, 16 and 20 weeks, respectively. From the berry appearance, After 8 weeks of storage, SO_2 had a poorer grapes, and after 16 weeks of storage with SO_2, 4 out of the 8 lines still had the same level of appearance before storage. In general, the berry flavor without SO_2 could retain 7 While those treated with SO 2 could be preserved for more than 12 weeks.Without SO 2 2- treatment, 6 out of the 8 cultivars reached 23-60% during 8 weeks of storage.Compared with SO 2 treatment , And 16% of the rotten fruits stored for 16 weeks had only 3% or less of the damage.Esophageal damage caused by SO_2 was 0 ~ 59%, but only two cases caused the flavor and appearance of the berries to go beyond the requirements of preservation.Under the condition of SO_2 treatment, 8 After 12 weeks of storage, the berries were still very good. Suffold Red lines were judged to be more prominent. After 20 days of storage with SO_2, berry appearance and berry flavor were just 3.5% of that of the fruits stored before storage.
