摘要： 本文叙述了钴—60辐照处理苹果在贮藏保鲜过程中的一些生理效应,试验结果表明:辐照处理能有效的抑制内源乙烯的产生,从而延长苹果的贮藏期.辐照剂量在0.3—1.0KGY时,辐照剂量与苹果的乙烯释放速率、产生乙烯的总量呈负相关(r=-0.986),使辐照处理的苹果,贮藏了八个多月后,外观与品质变化不大.辐照处理对苹果的蛋白质、还原糖、纤维素、酸度等营养成份没什么影响.

Abstract: This paper describes some physiological effects on apples irradiated with gamma ray in storage process. Experiment results indicate that irradiation can inhibit production of ethylene, which, in turn, can postpone the ripening and senility of apples. Therefore storage life of irradiated apples is longer than non-irradiated apples. There is a negative correlation both between the dose of irradiation and the rotal amount of ethylene and between the dose of irradiation and the rates of ethylene release. The quality and appearance of irradiated apples stored after for eight months have no significant variation. The irradiation has little effect on apples in such nutritional contents as protein, raducing sugar, cellulose and acidity.
