摘 要 ：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。

Abstract:In trials from.1978 to 1984 Jonathan apple (Mains domestics Borkh ) fruit were irradiated at doses of 0,24,49,73,97 and 146 krad and then stored in cooled house with natural ventilation.The dose rate was 44 rad/min.Four to seven replications were used for each treatment.Daring the seven-year test period about 5 tons fruit had been treated.Seven-year trial showed that the incidence of Jonathan spot could be significantly reduced by irradiation.The incidence of irradiated fruit was 5% while that of control was 55%.Appropriate radiation dosage was 49-73 krad.Irradiation did not affect fruit taste quality and chemical components.
