以江苏省泰兴市地方品种为材料，采用钴－６０辐照新技术，对不同辐照时期、辐照剂量、包装、前处理和贮藏条件等因素进行试验。结果表明，新收获银杏果仁，经一定包装后，保鲜剂量０２ｋＧｙ较好，种胚已充分后熟的银杏，则需采用灭菌贮藏剂量３ｋＧｙ。辐照后常温贮藏，３个月保鲜效果在９５％以上，辐照前处理有一定保鲜效果。
Taking Taixing City, Jiangsu Province, as a material, the cobalt-60 irradiation technology was used to test the factors such as irradiation duration, irradiation dose, packaging, pretreatment and storage conditions. The results showed that the newly harvested ginkgo nuts, after a certain package, the preservation of the amount of 0 2kGy good, embryo has been fully ripe ginkgo, you need to use the sterilization storage dose 3kGy. Storage at room temperature after irradiation, 3 months preservation effect of more than 95%, pre-irradiation treatment has a certain effect of preservation.
