Journal of Ginseng Research, volume 6, issue 1, 1982, Pages 1~10
This study was conducted to determine effect of fruits removal on the CO2 exchange rates (CER) and growth of ginseng plant. Fruit of 2, 4 age plant removed at 7, May. The results of these investigations are as follows. 1. The net photosynthetic rates of the ginseng bearing fruits increased to a considerably greater degree than that of the ginseng without fruit in each ages. 2. The total dry matter per plant in bearing fruit (40.24g) had produced more dry matter than that of non-fruiting plant (38.13g) , but the root 4.y matter in fruiting plant (26.2g) had produced less dry matter than that of non-fruiting plant (27.1g) in 4 age. 3. The ginseng plant in bearing fruit did not influence the dry matter of stem and leaf. 4. The maximum RGR of root (17, June) was slower than that of fruit (4, June) .

This studies were conducted to investigate the changes of saponin pattern, pH and organic acid contents of malt wort added ginseng components during alcoholic fermentation by Sacch. uvarum. The results are as follows. Saponin patterns of fermented wort were same as that of the non- fermented wort, but the weight of former was decreased comparing to that of the latter. pH value of fermented wort contained 0.1∼0.5% of ginseng extract were almost same as that of control(PH 4.23). Lactate, pyruvate, succinate and fumarate, pyroglutarate and citrate contents of the fermented wort were increased by the addition of ginseng extract and pyruvate content, particularly, was increased from 28.4 to 214mg/100 ml while that of control was 33.2mg/100m1. Citrate content of fermented wort contained ginseng saponin was almost same as control (37. 5mg/100m1) . But pyruvate content was tower 4-8.6mg/100m1 than that of control(33.2mg/100m1) .
Studies on the Manufacturing of Ginseng Soft Drink II. Effect of pH and heat treatment on the stability of panaxadiol saponins
Journal of Ginseng Research, volume 6, issue 1, 1982, Pages 25~29
This investigation was carried out to study the influence of pH and heat treatment on the ginsenosides in the white ginseng extract. Changes in ginsenosides (Rb1, Rb2, ,Rc, Rd) and free sugar were measured by the peak area variation of HPLC chromatogram during 25 hours heat treatment at the various level of pH. It was found that :(1) The peak areas of Rb1. Rb2, Rc and Rd on the HPLC chromatogram were decreased remarkably below pH 4.0 and more decrease was found as the temperature and heating time increased. (2) Those of glucose and arabinose were increased remarkably. It is considrered that the increase of glucose and the formation of arabinose result from the hydrolysis of ginsenoside( Rb1, Rb2, Rc, Rd) linked with sugars.
Characteristics of Water Vapor Sorption Phenomena of Powdered Foods
Journal of Ginseng Research, volume 6, issue 1, 1982, Pages 30~37
This study was conducted to investigate the water vapor permeability of packaging film, Al- foil laminated paper, and sorption properties of dehydrated and powdered foods. The results are as fellows. 1. Absorption rate of each products was greately affeoted by physicochemical properties of foods rather than initial moisture contents of the products. 2. The absorption rate of each products were in the order of freeze dried coffee, spray dried coffee, freeze drie4 ginseng extract, spray dried ginseng extract, ginger tea, black tea, citrus juice Powder and ssang wha tea. 3. Most of the products such as freeze dried coffee, spray dried coffee, freeze dried ginseng extract, ginger tea and black tea have shorter than a month of shelf life. 4. The stability of the products were greatly affected by its desorption properties than the degree of desorption of moisture. 5. Water vapor permeability of packaging materials which are laminated Al-foil with polythylene and glassin paper were mainly affected of thickness of Al-foil and polyethylene.
Studies on the Optimum Light Intensity for Growth of Punux ginseng ( I ) Effects of Light Intensity on Growth of Shoots and Roots of Ginseng Plants
Journal of Ginseng Research, volume 6, issue 1, 1982, Pages 38~45
To determine the optimum light intensity for growth of ginseng plants, change of temperature, moisture content in son, occurrence alternaria blight, defoliation rate, chlorophyll contents, and growth of shoots and roots were investigated under different light intensity such as 5%, 10%, 20% and 30% light transmittance rare(L.T.R.). The results obtained were as follows. 1. Maximum temperature under the shading was increased as the increase of light intensity, whereas soil moisture content decreased 2. As the increase of light intensity, stem and Peduncle length, leaf area, and chlorophyll contents decreased significantly but length and width of the leaf was not significant, while stem diameter, special leaf weight and chlorophyll a/chl. b ratio increased 3. Stem color was shown dark purp!e as the increase of light intensity. 4. Photosynthesis during the day was highest at 9 A.M. and decreased as time passed in all plots. The means of photouynthesis during the day showed in the order of 20%, 10%, 30%, 5% L.T.R., and optimum light intensity for highest photosxthesis was 18.4% L.T.R. by theoritical equation. 5. It was showed a tendency that alternaria leaf blight of ginseng plants was increased as the increase of light intensity. 6. Defoliation rate of ginseng plants was increased as the increase of light intensity, especially all plants were defoliated by late June without shading. 7. Yield percentage of the rear line was increased as the increase of light intensity. Root weight per plant showed in the order of 20%, 10%, 30%, 5% L.T.R., and optimum light intensity for the best yield was 18.5% L.T.R. by theeritical equation.
Effect of Soil Fumigation on Growth, Root Rot, and Red Discoloration of Panax ginseng in Replanted Soils
Journal of Ginseng Research, volume 6, issue 1, 1982, Pages 46~55
The effect of soil fumigation on the growth, yield, root-rot and red discoloration of 2 year-old ginseng, Panax ginseng C. A. Meyer was investigated in the ginseng replanted fie14 Six soil fumigants, Cylone, Basamid, D-D, Dowfume MC-2, Telone C-17, and Vapam were applied in March, 1980, and 2 year-old ginseng plants were transplanted in April, 1981, and sampled in August, 1981. Growth an yields in Cylone and Basamid treated plots in the replanted soil were better than those in control. Especially, growth and yields of ginseng in Cyclone treated Plots were comparable to these in untreated virgin soil. Control effect of soil fumigants used on root-rot was in the order of Cylone, Basamid, Telone C-17, and the lest of them showed neglect fur effect. Frequency of red discoloration was 8% in Cyclone treated plots, 9% in Basamid treated plots 83.3% in the untreated ginseng replanted soil, and 2.5% in the untreated virgin soil.
The Effects of Various Dehiscence Materials, Growth Regulators and Fungicides on the of Ginseng Seed ( Panax ginseng C A. Meyer )
Journal of Ginseng Research, volume 6, issue 1, 1982, Pages 56~66
The effects of various dehiscent application such as dehiscent materials (big chaffs, vermiculite etc.), growth regulators and agricultural chemicals (plant protector.) on stimulation of dehiscence and shortening of dehiscent period were investigated Results obtained were as follows : 1. The moisture content of endosperm and seed coat at 10 day after dehiscent application amounts between 40% and 50%. 2. Endosperm diameter was increased with time of stratification, and the embryo growth showed in linear function, 3. Non-dehiscent seed showed also normally development of embryo, and the property of dehiscence dependent from physico-chemical nature of ginseng seed coat. 4. The best dehiscent materials were big chaffs and followed vermiculite, sand and sand with big chaffs. 5. The effect of dehiscence of ginseng seed showed higher activity in fungi than in bacteria in general. 6. Agricultural chemicals ( plant Protector) reduced the dehiscent rate of ginseng seed 7. The best timing of dehiscent treatment was between August 1 and August 10 but the smaller amount of dehiscent rate after August 10 dehiscent appllication indicated that big chaffs and growth regulator treatment may be controlled shortening of dehiscent period of ginseng seed.
Morphological Characteristics of Inflorescence, Flowering Bud, Fruit and Leaf of Korean Ginseng
Journal of Ginseng Research, volume 6, issue 1, 1982, Pages 67~74
To clarify the morphological characteristics of Korean ginseng cultivated, the shapes and frequencies of Inflorescence, flowering bud, fruit, and leaf were investigated. The shapes of inflorescence, flowering bud and fruit, and leaf were divided into 6, 3, and 7 groups, respectively. The frequencies of these shapes were not significantly different according to the planting positions.
Biochemical Study on the Mechanism and Protection of Ginseng Root-Rot Disease
Journal of Ginseng Research, volume 6, issue 1, 1982, Pages 75~83
In this study it was found that the enzyme activities of diseased ginseng contributed greatly on the development of its root-rot disease. The 4i sensed ginseng showed higher activities of
-amylase, p amylase, invertase, catalase, and cellulase than those of fresh one. The increased enzyme activities of diseased ginseng were originated in those from infected pathogens, which showed a proportional relationship between enzyme activities and root-rot power of them. The increases of enzyme activities during incubation of inoculated ginseng could be considerably depressed by controlling culture environments as to temperature below 4
, pH 8-9, and relative humidity about 60%, Some metal ions and organic reagents also inhibited the enzyme activities of diseased ginseng. But their inhibitory effects were not so great that they might be used to protect the disease.
Water Physiology of Panax ginseng Charcteristics of reproductit.e organs and precipitation rate and humidity of shade system.
Journal of Ginseng Research, volume 6, issue 1, 1982, Pages 84~99
Water content and its seasonal change in reprodltctive organs were reviewed in relation to cultivation practice s. Precipitati on and humidity under shade roof were reviewed in relation to shading ,jystem and environmental factors. High water content of reproductive organs suggests vulnerability to water stress during reproductive growth stage. Watering during dehisconce treat menu seems to keep optimum temperature but cnoventional practice seems to be too often In watering. Information effe on water physiology of seeds is too rare to develop seed storing method and ctive seed use. Dehiscent mechanism was considered in terms of water absorption of embryo. Precipitation rate of conventional shade roof reaclled to 38% and at line level 50% and varied with shade patterns. Precipitation rate under shade has been investigated for itself but should be investigated in relation to light intensity and soil moisture content Relative humidity under shade depends mainly on air humidity and soil moisture, considerably on shade materials and lithe on pole height, bed width or plant density. Since relative humidity was lower in afternoon it was often less than 50% even in summer with high temperature suggesting possible disorder of phi biological function especially in photosynthesis. More information was needed on optimum humidity for productive physiological function of leaf.
