바늘(Allium Sativum L.)의 저장중(貯藏中), 발아(發芽)로 인(因)한 손실(損失)을 억제(抑制)하고 저장기간(貯藏期間)을 연장(延長)할 목적(目的)으로 한국산(韓國産) 마늘에 $^{60}Co-{\gamma}$선(線)을 조사(照射)하여 실온(室溫)에 저장(貯藏)하고 발아억제(發芽抑制), 성분변화(成分變化) 및 부패균(腐敗菌)에 미치는 ${\gamma}$선(線)의 영향(影響)을 조사(調査)하였다. 1. 무안산(茂安産) 마늘의 후면기간(休眠期間)은 당진산(唐津産)에 비(比)하여 짧고, 발아기(發芽期)가 발랐다. 2. 양품종간(兩品種間)의 ${\gamma}$선(線)에 대(對)한 저항성(低抗性)에는 차이(差異)가 있음을 인정(認定)하였다. 3. 10Kard에서 양품종(兩品種) 다같이 종전(宗全) 발아억제(發芽抑制)가 가능(可能)하여, 당진산(唐津産)은 5krad에서도 그 효과(效果)를 인정(認定)할 수 있었다. 4. 조사구(照射區)에서 수분(水分) 및 중량(重量)의 감소율(減少率)이 낮았다. 5. 300Krad까지의 선량내(線量內)이서는 당함량(糖含量)의 증감(增感)에 큰 영향(影響)이 없었다. 6. Aspergillus niger와 Aspergillus aliaceus는 300Krad 조사(照射)에서 거의 발아(發芽)가 없었다.
In order to inhibit sprouting of garlics during the storage period and the extend their storage life, garlics were irradiated by gamma-rays $(Co^{60})$ and kept at room temperature. The effects of gammaradiation on sprouting inhibition, chemical contents during storage, and spoilage molds were investigated and the results are as follows. 1. Garlics obtained from Muan showed the shorter dormancy period and sprouted earlier than those from Dangjin. 2. Regarding the radioresistance, some differences were found between garlics from Muan and Dangjin. 3. The sprout of garlics from both areas was completely inhibited at 10 Krad and remarkable effect on sprouting was observed even with 5 Krad in case of garlics from Dangjin. 4. The rates of loss in moisture and weight were lower in irradiated lots than control. 5. Change of sugar content was not observed with ${\gamma}-irradiation$ under 300 Krad. 6. Spores of Aspergillus niger and Aspergillus alliaceus were little germinated at a level of 300 Krad.
