착유방법을 달리하여 얻은 기름골 기름을 37℃와 60℃에서 저장 중 산화안정성을 조사한 결과는 다음과 같다. 1. 저장 중 기름의 산가는 기간이 경과함에 따라 증가하였는데, 37℃에서 저장한 것보다 60℃에서 저장한 것이 높게 나타났고, 유기용매로 추출한 기름의 산가가 가장 높았다. 2. 저장 중 기름의 과산화물가는 37℃에서 저장한 기름의 경우 점차적인 증가를 보이다 저장 120일 이후 급격한 증가를 보이고 150일 이후 다시 감소하는 경향을 나타내었고, 60℃에서 저장한 기름은 37℃에서 저장한 기름보다 같은 저장기간에서 과산화물가 더 높게 나타났고, 그 경향은 저장 210일째까지 증가가 지속되어졌다. 3. 지방산은 oleic acid가 가장 주된 지방산으로 존재하고 있었고, 지방산은 저장기간이 경과함에 따라 palmitic acid, stearic acid, linolenic acid에서 근소한 증가와 oleic acid, linoleic acid는 약간의 감소 경향을 보였으나 저장에 따른 뚜렷한 변화는 볼 수 없었다. This study was carried out to investigate the oxidative stability and fatty acid composition during storage of chufa oil. Chufa oil was roasted at 170℃, 150℃, non-roasting or solvent extracting and stored at 37℃ or 60℃. The acid value and peroxide value of chufa oil at 60℃ were higher than their at 37℃. The acid value of chufa oil showed the trend of increase in all the samples and that of solvent-extracted oil was the highest during the storage period. The peroxide value of oils was gradually increase on the 120th day but significantly increased between 120th and 150th day. Oleic acid was the major fatty acid in chufa oil. Palmitic acid, stearic acid and linolenic acid increase and oleic acid and linoleic acid decreased during storage period. They were changed slightly and the obvious differents were not observed according to storage period.

This study was carried out to have basic and applied informations to find the optimum nitrogen fertilization level for organic cultivation and to investigate early growth characteristics of Schizandra chinensis Baillon. Different application levels of the organic fertilizer were based on the recommended rate of N fertilizer. Five different levels of the organic fertilizer were applied to S. chinensis and early growth responses such as the length of vine, the diameter of vine, the number of leaves, and the number of branches were investigated. Lengths of main and total vines were shown longer at the level of 1.0 time organic fertilizer than those at others. The vine length at early growth was the highest at the level of 1.0 time organic fertilizer among the treatments. Stem diameter was shown thicker level of 1.0 time organic fertilizer than others on August and September, whereas on October it was the thickest in the conventional cultivation. Number of leaf was increased higher at the level of 1.0 and 2.0 times organic fertilizer than that in the compared to conventional. The number of branches was appeared the lowest at the level of 1.0 time organic fertilizer at early growth, however they were increased through progressing their growth stages. They were not significantly difference among the treatments except for the level of 2.0 times organic fertilizer. Based on the research results, the growth of S. chinensis was commonly higher at the level of 1.0 time organic fertilizer compared to other treatments.

This study was conducted to improve perilla seed oil quality and to select the excellent mutant suitable for various uses. The seeds of three varieties, Okdong, Yeupsil and Suwon 8 were reated with EMS 0.5% and γ-ray 15KR to 40KR. The M₂ selected plants were analyzed on their oil and fatty acids composition. Oil content of 142 selected lines were ranged 34.3%~47.4% with the mean of 41.0%. The range of saturate fatty acid was 3.44%~11.36% with the mean of 7.17% and unsaturate fatty acid was 80.03%~96.87% with the mean of 92.81%. The contents of linolenic acid in M₂ population of Okdong showed higher than those of Yeupsil and Suwon 8 with the effective mutagenetic agent r-ray. The promising line which have 72.58% of linolenic acid was selected from Okdong population. Thus this line could be used as gene source for breeding of high linolenic acid perilla varieties. The oleic acid correlated with linoleic and linolenic acid negatively, saturate fatty acid was highly correlated with unsaturate fatty acid negatively being the correlation coefficient r=-0.4903.
