Abstract

In order to determine the optimun condition for the long term storage of potatoes by irradiation combined with natural low temperature, the dose range and irradiation time after harvesting of two varieties were investigated. Although optimum dose of potatoes and was different according to the variety 12.5krad seemed optimum untill 15-30 day after harvesting and 15krad was for later than 45 day after harvesting. The sooner the irradiation was efficient after harvesting. Optimum dose irradiated group were better in change of sprouting, rotting, weightloss and shrivelling and was extended the storage period more than four months compared with control at natural low temperature storage room.
