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.

감자의 장기안전저장법(長期安全貯藏法) 개발(開發)을 위하여 적정조사선량(適正照射線量)및 적정조사시기(適正照射時期)를 구명(究明)한 결과(結果)는 아래와 같다. (1) 품종간(品種間)에 차이(差異)는 있으나 수확후 $15{\sim}30$일(日) 사이에 방사선(放射線)을 조사(照射)할때는 12.5krad의 선량(線量)이 적당하고, 수확후 45일(日) 이후에 조사(照射)할때는 15krad 정도의 조사(照射)가 필요(必要)하며, 가급적 수확후 휴면기간(休眠期間)중 빨리 조사(照射)하는 것이 유리하다고 본다. (2) 적정조사선량(適正照射線量)에서의 조사구(調査區)는 무처리구(無處理區)에 비(比)해 물리적성질(物理的性質)이 우수(優秀)하였으며, 방사선조사(放射線照射) 후(後) 자연저온저장고(自然低溫貯藏庫)에 저장(貯藏) 함으로서 무처리구(無處理區)보다 저장기간(貯藏期間)을 4개월이상(個月以上) 연장시킬수 있었다.
