許仁玉 濟州敎育大學校 1977 論文集 Vol.7 No.-

Following are the results surveyed and analyzed, by March 20, 1977, about the geographical distribution and peculiarity of native species of citrus growing spontaneously all over CHE Ju-Do; with a view to protecting their exterminaiton, to cultivation new improved species, and to develop them as herb remedy or processing materials. 1. Origin and growth : Such various species as Dang-Yuja, Yuja, Chung-gyul, San-gyul, Dongjong-gyul, Yu-gam, Ji-gak, Gum-gyul, Danggum-gyul, Doong-ja, Byong-gyul, Wae-gyul and Sokgum-gyul had been grown long before in CHE Ju-Do, Their fruits were presented to the court as a tribute or made habitual use of as herb remedy materials and rate fruits. Therefore, with a positive encouraging measure, the local government established many orchards in many areas, which made possible remarkable progress in growing skill,. When the improved species were introduced into this community, growers tended to neglect the growing management, so the native species gradually came to grow senile or to wither to death, resulting in only seven species surviving and the others are all exterminated. 2. Species distribution and its realities : The remaining seven species are Dang-yuja, San-gyul, Byong-gyul, Yuja, Ji-gak, Chung-gyul and Dongjong-gyul, which amounts to 1.351 trees in total number ; 678 of Dang-yuja, San-gyul 337, Byong-gyul 232, the others like yuja, Chung-gyul and Jigak are so few in the only one shrub of Dongjong-gyul remaining. As to the age of shrubs most are 100 years old or more and there four shrubs which are over 200 years in age. 3. Growing scale and production : In the present time farmhouses which maintain the native species number 748, among which 420 houses or 83% of all holders have one respectively and those which over four shrubs are no more than 14 house, whereupon each fails to produce economic unit of scale. 4. Growth realities : There being many which grow senile, the shrubs growing and bearing in normal state number only 335 (25%) and the other 548 corresponding to 41% show year alternate fruit-bearing. Those nearly withering to death and thus unable to revive are 207 in total. 5. Quality : Compared to the improved ones, the fruit's external appearance doesn't look good but they retain their peculiar taste and good fragrance. 6. Their usage and processing : Species like Dang-yuja, Byong-gyul, Donggong-gyul, would be preferable to the usage as fresh fruit, such species as Dang-yuja, Chung-gyul, Byong-gyul and Dongjong-gyul to the making of juice drink or processing, proper species for soft drinks from Yu-ja and Dang-Yuja and for the usage of herb remedy, San-gyul-pi (Jin-ip), Chung-gyul-pi(Chung-pi), Ji-gak and Gyul-pi would be practically valuable, By-products from such species for herb remedy amount to 1.070 kinds and are now made made habitual use of. 7. Prospects and problems : The native species are growing scattered in so small scale, so they cann't comprise an economic unit of scale. Thereupon, due to likely negligence of the managemnt, many shrubs are withering to death, so it would be grown into promising local industry if we should be successful in their collectivization for growth and if we could develop how to process and economically use their fruits.

The difference of bearinge condition acted on the same shrub. The effect on the qualities follows : 1. The more outside bearing produced higher condent of soluble solid with less free acid. 2. The higher stand of bearing increased the content of both soluble solid and free acid. 3. The brearing angle faced up ward, it increased the content of free acid and the more outsider showed better qualities. 4. The more foliage on the bearing branch, the bigger and less in the content of free acid the fruit qrew. 5. The later harvesting time produced higher content of soluble solid and less free acid of the fruit. 6. It showed no considerable difference in the standard deviation of the soluble solid but the free acid held less degree of the standard devition depending upon being later of harvesting time.

溫州밀감의 品質改善에 關한 硏究

許仁玉 濟州敎育大學校 1975 論文集 Vol.5 No.-

The following experiments are made to investigate the data and ways to improve the quality of Satsuma orange. The influence the conditions of location act upon the quality of Satsuma orange. 1. The present condition of quality depending upon the local producing area of orange shows that the orchards nearer from the coast produce thinner skin and less contents of free acid but poor quality in fruit-coloring. 2. Trees growing in the intermediate area produce higher contents of the total soluble solids and better quality in fruit-coloring butthose in the area more than 2km from the coast show thicker fruitskin and higher contents of free acid but the total soluble solids are insufficient, which results in poor quality of fruits. 3. As to the relationship between the landforms and the quality of fruits, the fruits produced on the slope show higher contents of the total soluble solids but less contents of free acid than those on the flat land but there can not be found any real difference in Wase Satsuma orange. 4. The quality related with the soil shows that the trees grow better on the wolcanic tuff soil than those on the clayish soil but result in poor quality of fruts. The influence that Ethrel (2-chloroethane phosphonic acid) acts upon the coloring of Satsuma orange. 5. To press forward coloring, treated the harvested fruits with 200 PPM, 300 PPM, 500 PPM of Ethrel respectively, which results in better effectiveness treated with denser contents but those treated with 500 PPM bring in chemical injuries. 6. Treatment with 300 PPM shows more effective than with the other methods and presses forward coloring on the fruits colored more than half but no effect canqe found on green fruits 7. When treating the fruits with Ethrel, high temperature brings forth good coloring but the calyx removed, so it is reasonable to treat at the temperature of from 15 to 20 degree with Centigrade. 8. It is effective to sprinkle during the maturing period as Ethrel acts in decomposition oi Chlorophyll but is not related with formation of carotenoid in Satsuma orange.

Agrobacterium rhizogenes strain R1000에 의해 유도된 Atropa belladonna 모상근을 배지별, NAA, IBA, IAA, 2,4-D를 농도별(0.01-100 mg/l)로 첨가한 NN액체배지에서 생장량과 tropane alkaloid 함량을 HPLC로 이용하여 정량하였다. 모상근 배양 30일째의 각 auxin의 농도별에 따른 생장율은 고농도보다 저농도일때 대체적으로 양호하였으나, 0.1mg/1 2,4-D농도에서는 callus화 하였고 10mg/l 2,4-D, 1mg/l IBA일때 2.96g, 2.36g으로 대조구보다 2.3배의 생장량을 보였다. 농도별에 따른 Tropane alkaloid 함량은 atropine이 대조구 0.141%, 원식물체가 0.059%로 나타났으며, 0.01mg/l NAA와 0.1mg/l IAA에서 배양한 모상근이 각각 1.378%, 1.814%의 생산을 보여 대조구와 원식물체보다 9-30배의 생산을 보였다. 또한 scopolamine 함량은 대조구와 원식물체는 각각 0.109%. 0.050%에 비해 0.01mg/l NAA에서 배양한 모상근에서 0.505%로 대조구 원식물체보다 4-10배의 생산량을 보였다. The study aimed to measure growth rate of Atropa belladonna hairy root cultured under medium, various auxin(NAA, IBA, IAA, 2.4-D) and auxin concentration(0.01-100mg/l) and investigated tropane alkaloid content using HPLC. The growth rate of hairy root cultured for 30 days in MS and NN liquid medium were higher in NN medium as 3.51g than MS medium, growth rate of belladonna hairy root cultured in NN medium added various auxin and auxin concentration was the most effective in low concentration than high concentration, especially, was best in the medium supplemented with 0.01mg/l 2,4-D. Atropine content of hairy root cultured in 0.01mg/l and 0.1mg/l IAA produced 9-30 times than control and normal plant. scopolamine measured each 0.109%, 0.050% in control and normal plant, hairy root cultured in 0.01mg/l NAA produced 4-10 times than control and normal plant.

溫州蜜柑(Citrus unshiu Marc.)葉의 Abscisic Acid含量에 미치는 Water stress의 影響

許仁玉,金星徹 濟州大學校 基礎科學硏究所 1993 基礎科學硏究 Vol.6 No.1

溫州蜜柑 (Citrus unshiu Marc.)葉의 abscisic acid(ABA) 含量에 미치는 water stress의 影響에 대하여 調査하였다. HPLC에 의한 ABA 分析에 있어서 cis-ABA는 7.8分에 나타났고 紫外線處理에 의한 不活性形態인 trans-ABA는 7.2分에 나타났다. 葉齡에 따른 ABA含量은 ??葉이 가장 높았고, 夏葉이 가장 낮았으며 葉齡이 增加할수록 ABA含量이 增加하였고, 水分減少에 대한 抵抗力은 幼葉일수록 높게 나타났다. 乾燥處理에 따른 葉內 ABA含量은 乾燥日數가 增加할수록 ATA含量도 增加하였고, ABA含成率은 舊葉보다 春葉이 높게 나타났다. 夏葉의 ABA는 舊葉 또는 春葉에서 合成된 後 夏葉 으로 이동되어 蓄積된 것으로 推測된다. The effects of water stress on changes in endogenous levels of abscisic acid were investigated in Citrus unshiu Marc. In ABA analysis by HPLC, cis-ABA appeared at 7.8min. and trans-ABA, inactive form by UV irradiation appeared at 7.2min. The content of ABA in fresh weight base increased gradually with aging of the leaves and was highest in the defoliated leaf. The resistance to the deficiency of water was highest in the summer leaves and the rate of ABA synthesis was higher in the spring leaves than the old leaves in response to drought. ABA content in summer leaves was increased by translocation of ABA with the assimilates from spring and old leaves to the importing summer leaves.
