제주지방에서 양파 저장에 관한 γ-ray 처리와 저장장소에 대한 실험을 하였다. 발아율은 저온저장, 상온저장, 동굴저장에 관계없이 무처리 양파는 약 5개월째부터 발아와 발근이 시작되었고 시간이 지날수록 증가하였으나 8월상순경에는 0Krad에서 동굴에 저장한 것은 50%, 상온에 저장한 것은 20%의 발아율을 나타내었다. 그러나 3Krad, 6Krad 처리한 것은 6개월까지는 거의 발아하지 않았다. 중량 감소는 발아와 밀접한 관계가 있는데 발아가 시작하기 전 40일 까지는 모든 처리에서 차이가 없었지만 발아가 시작되면서부터 급격히 감소하였다. 저온저장한 것은 부패율이 약 5~10%내외로 7개월후에도 식용이 가능하였으나 상온에 저장한 것은 0Krad에서 50% 정도 부패한 반면 3 Krad 및 6 Krad를 조사한 것은 저온저장인 경우 5%, 동굴저장인 경우 30 - 35%, 상온에 저장한 것은 30% 정도의 부패율을 나타내었다. 방사선조사의 다당류 변화에 대한 연구는 비교적 많이 이루어졌는데 동굴저장과 상온저장에서는 저장초기에는 3Krad 및 6Krad 조사한 것이 0 Krad보다 다소 증가 했으나 후기로 갈수록 역시 처리한 것이 양은 적으나 0Krad보다는 증가한 사실을 알 수 있었다. Allium속 채소류에 많이 들어있는데 유황은 저장장소에 관계없이 0Krad에서는 저장후반기로 갈수록 적어졌고 냉장저장한 것은 3 Krad 및 6Krad의 선량간에는 다소 차이가 있었으나 저장초기에는 유황함량이 증가하다가 12월 말경 부터는 점차 감소하는 경향을 보였다. For storage extension of Cheju grown onions, γ-ray irradiations with doses of 0Krad, 3Krad, and 6Krad were applied to onionbulbs produced in Cheju Island and their quality were compared during storage at natural cavern, low temperature (2℃), and ambient temperature. Sprouting began approximately from five months storage regardless of storage types which increased as storage extended. From early August, sprouting occured in natural cavern storage as high as 50%, in ambient temperature it was 20% in 0Krad, whereas onions with 3Krad and 6Krad γ-ray dose did not show sprouting until six months. No significant weight loss were observed in all the treatments until sprouting occured after 40 days of storage. The loss, however remarkably increased after 40 days of storage indicating that weight loss is closely correlated with percent sprouting during storage. Low temperature stored onions which showed 5-10% of rotting rates were still edible. Rotting rates reached to as high as 50% for unirradiated ambient temperature stored onions after seven months while they were 5%, 33%, and 30% in low temperature, natural cavern, and ambient temperature respectively in irradiated groups. Sugar contents were slightly increased in later period in irradiated onions under ambient temperature storage although sugar contents which included in Allium vegetables generally decreased in later storage of unirradiated onions. Sulfur contents slightly increased in early storage in irradiated onions while showed gradual decrease although the differences were not significant.

This study was performed to investigate: The ecological difference of two ecotypes "Seushan (northern) and "Cheju(southern)" The effect of temperature (low. high. alternative) and long day treatments on the growth and bulb formation in two ecotypes Translocation of growth regulators and contents of total sugars in garlic plants Identification of isozyme existing in garlic plants by the electrophoretic method. The results are summarized as follows: 1. The experiment of temperature and long day treatments. Sprouting and early growth of the southern type were accelerated by low iemperature treatment but those of long day treatment were not affected. In plant height and leaf sheath length. the southern type was increased more than the northern type until March 20 and the plants that were treated with low temperature were increased considerably as compared with the control There was no difference in the total leaf numbers between two ecotypes but low temperature treatment romoted those as compared to the control. 2. Ecological experiment of two regions The plant height of the southern type was accelerated until March 25 i n Cheju and March 10 in Suweon. but the plant height of the northern type was promoted after April 20. The growth of leaf length and leaf sheath lentth showed no dlfference durting winter. but after March 10 the southern type was increased in Suweon and Cheju. there was no difference in clove number and bulb weight within the regions and seeding time. but those of the southern type were increased as compared with the northern type 3 Analysis of sugar Low temperature treatment tended to increase concetrations of sugar as compard with control and the difference between cultivats was clear Friictosan was increased as the plants grew. especially at the later period of the whole growth with ever): treatment 4 Bioassay at growth regulators Af Rf 0.5-0.6 and Rf 0.4-0.5 Glbgberellin-like substances were detected from the leaf and leaf sheath of northern type and inhibitors were detected at Rf 0.7-0.9 While 5. The change of Isozyme patterns It was noted that the isozyme patterns were similar between two ecotypes in peroxidase. There was no difference at the bands which means acid phosphatase in two types. There were three or four bands which showed Malate dehydrogenase. but also showed the similar tendency according to the cultivars and every parts.

This experiment was conducted during the period from September 2, 1982 to June 5, 1983 in order to examine the suitable planting time and growing condition in Cheju Island using the Sourthem garlic (Cheju jaere) and Nourthem garlic (6-clove garlic). 1. The earlier the garlic was planted, the higher the top part growth and 6-clove garlic decreased more than in early period. However, rather higher than Cheju jaere from the beginning of May. 2. The earlier the Cheju jaere was planted, the plant weight, top part weight increased remarkable more than 6-clove garlic. 3. As the bulb index was below 0.5 in the bulb formation of Cheju jaere, there was no difference between the planting time, but because the bulb formation of 6-clove garlic was over 0.5, the bulbing was slowing down. 4. Cheju jaere differentiated the clove in March. 10 and 6clove garlic April. 2 but the earlier the garlic was planted, the earlier clove differentiation and there was about 25 days difference between two varieties. 5. The later the Cheju jaere garlic was planted, the secondary growth increased. However, the earlier the 6-clove garlic was planted, the secondary growth increased.

濟州地方에서 한라부추(Allium taquetii) 栽培法 確立에 關한 硏究 : Ⅰ. 赤色光과 植物生長調節劑가 種子發芽에 미치는 영향 Ⅰ. Effect of Red Light and Plant Growth Regulators on Seed Germination

朴庸奉,康勳,金基澤 제주대학교 1991 논문집 Vol.33 No.-

한라부추 種子發芽에 對한 溫度, 光質(赤色光), 低溫處里 및 몇가지 植生物長調節劑를 處里하여 發芽하는 狀態를 調査한 結果 다음과 같은 結論을 얻었다. 1. 한라부추의 發芽適溫은 20∼25℃였으며 高溫인 30℃에서는 發芽가 極히 抑制되었다. 2. 赤色光은 15∼20℃ 溫度에서는 發芽促進 效果가 있었지만 25℃以上의 溫度에서는 그 促進效果가 喪失되었다. 그리고 모든 溫度에서 暗處理와 類似한 發芽樣相을 보였다. 3. 低溫處理 한 것은 對照區와 거의 비슷한 傾向을 나타내었다. 4. NAA는 發芽抑制 效果가 나타나 對照區보다 오히려 發芽率이 떨어지는 傾向을 나타내었다. GA는 25㎎/ℓ, Ethephon은 50㎎/ℓ, BA는 10㎎/ℓ에서 發芽가 가장 促進되었으나, Ethephon과 BA의 경우 濃度가 높을 수록 發芽抑制 程度가 심하였다. In view of seed germination of Halla gynmigit (Allium taquetii) its known to grow wild (natually) at the 110m level of Mt. Halla. A study was conducted to see if several plant growth regulators, high and low temperature and red light treatment have any promotive influence on the germination of Halla gynmigit seed and its practical value, when applied at various concentrations. 1) 20~25℃ showed promotion of germination of Hallh gynmigit seeds and shortened the mean number of days necessary for germination, while deleyed germination was observed if 30℃ was applied. 2) Red light promoted the seed germination of Halla gynmigit at 15~20℃, but at the over 25℃, promotive effect was lost. 3) the low temperature treatment group was not more significantly influence than the control. 4) The NAA treatment showed the effect of germination retard, On the contrary, The germination percentage was decreased less than that of the control. However, GA 25㎎/ℓ, Ethephon 50㎎/ℓ, and BA 10㎎/ℓ promoted the germinaton percentage markedly. Especially. BA and Ethephon treatment at latively higher concentration levels resulted in less seed germination.
