自1978至1985年对红玉苹果进行了~(80)Coγ射线辐照试验,辐照剂量为24、49、73、97和146krad,剂量率为44rad/min。每处理重复4—7次,果实辐照后置自然通风库贮藏。七年共处理红玉苹果5吨多。试验结果表明:用~(60)Coγ射线辐照红玉苹果,能十分明显地降低其斑点病的发病率,对照果发病率为55%左右,辐照果为5%左右;比较适宜的辐照剂量为49-73krad;适宜剂量辐照对果实风味和化学成份没有不良影响。 ~ (80) Coγ-ray irradiation experiments were conducted on apple ruby ​​from 1978 to 1985 at radiation doses of 24, 49, 73, 97 and 146 krad at a dose rate of 44 rad / min. Repeat 4-7 times for each treatment, the fruits are irradiated and stored in the natural ventilation warehouse. Seven years co-processing ruby ​​apple more than 5 tons. The results showed that the incidence of spot disease was significantly reduced by ~ (60) Coγ-ray irradiation, the incidence of control fruit was about 55% and the irradiation fruit was about 5%. Appropriate radiation According to the dose of 49-73krad; appropriate dose of radiation on the fruit flavor and chemical composition without adverse effects.
