The Optimum Conditions for Induction of Ginseng Hairy Roots
Korean Journal of Plant Resources, volume 12, issue 1, 1999, Pages 1~9
The experiments were carried out to determine the optimum conditions for the induction of hairy roots in ginseng(Panax ginseng C.A. Meyer) by Agrobacterium spp. We were examined the antibiotics resistance of Agrobacterium spp and various ginseng parts, and the media for induction of hairy roots. The optimum concentration of NaOCl for sterilization of ginseng root segments without tissue damage with reduce of contamination was 7% NaOCl for 15-20 min and 9% NaOCl for 5 min, respectively. The more ginseng ages, the more contamination of ginseng root segment by sterilized in 7% NaOCl for 20 min, and especially in ginseng root segments with epidermis in six-year old roots. The growth of Agrobacterium spp were inhibited, but ginseng root segments was death in 30mg/L tetracycline. In 500mg/L cefotaxime or 500mg/L carbenicillin, the growth of Agrobacterium sup were inhibited, and root segments was grown normally. The optimum conditions for induction of hairy roots were using the root segments of three-year old ginseng cultured in 1/2MS medium supplemented with 500mg/L cefotaxime, and inoculation of Agrobacterium to root segments were better co-culture than smear method. After 2 weeks co-culture, the callus induced in cambium of root segments cultured in 1/2MS solid medium with 500mg/L cefotaxime. And then after 2 weeks, ginseng hairy roots were induced in callus of root segments. PCR analysis of rot C gene fragment confirmed that hairy roots were transgenic tissues.
Effect of Simulated Acid Rain on Water Status of Pinus densiflora and P. koraiensis
Korean Journal of Plant Resources, volume 12, issue 1, 1999, Pages 10~19
The water status of Pinus densiflora and P. koraiensis was observed after the treatment of simulated acid rain for every month August 1997 to March 1998. Both of the species showed increase of dry weight, water saturation deficit and epidermis transpiration after treatment of simulated acid rain (pH 3.5) for first three months. On the contrary, water content was decreased in both the species after three month of simulated acid rain treatment. The effect of simulated acid rain, however, became weaker after that and no big difference was observed after seven month of treatment. Water potential of the leaf of both species became lower than that of the control(pH 5.6) after seven month treatment of simulated acid rain. The cuticle layers of the epidermis and florins ring were damaged seriously and the size of the gap between stomata became bigger after the treatment of simulated acid rain.
Effect of Aqueous Extracts on the Callus Growth, Seed Germination, and Growth of Some Plants and Antibacterial Activity by Equisetum arvense L.
Korean Journal of Plant Resources, volume 12, issue 1, 1999, Pages 20~26
To investigate phytotoxic substances in Equisetum arvense, the aqueous extracts(25 and 8
) or the freeze-drying matter from aqueous extracts(
) of E. arvense were tested at different concentrations for biological activities on callus induction and growth, seed germination, seedling growth and antibacterial function. Callus induction and growth of Oryza sativa and Brassica campestris ssp. pekinensis were inhibited by the aqueous extracts at 8
and the higher concentrations. Callus growth of four receptor species was inhibited in order of Platycodon grandiflorum, Sesamum indicum, Brassica campestris ssp. pekinensis and Oryza sativa. Seed germination of Ο. sativa, S. indicum, and B. campestris ssp. pekinensis was not affected at low concentration, but it was proportionally inhibited by the higher concentrations. The greatest inhibition of seed germination was 28.3% compared to control, when 2,000
/ml of freeze-drying matter was applied to B. campestris ssp. pekinensis. Shoot growth was stimulated by 500
/ml of freeze-drying matter, but it was inhibited by the higher concentrations. Root growth was significantly inhibited compare to control at all concentrations. Antibacterial activity of freeze-drying matter didn't showed against Xantomonas oryzae and Eschrichia coli, but a small clear zone was formed by 500
of freeze-drying matter against Erwinia carotovora ssp. carotovora.
Changes of Root Yield and Essential Oil Content by Cultivated Years in Asaram siebold Mio
Korean Journal of Plant Resources, volume 12, issue 1, 1999, Pages 27~30
This experiment was conducted to investigate the change of root yield and essential oil contents by cultivated year in Asaram siebold Mio. Growth of aerial part such as plant height, leaf length and leaf width increased rapidly in two to three-year-old. Root length and root weight per plant were increased as cultivation year passed. Especially the speed of development was very fast in two and three-year-old alike aerial part. Root yield was the highest at five-year-old. The content of essential oil was decreased gradually as cultivation year passed. Methyleugenol content was increased, while safrole content was decreased by cultivated years. The increasing of methyleugenol content in four to five-year-old was not higher than three to four-year-old. In the result, it concluded that the optimum harvest time of Asarum sieboldi MiO is five-year-old cultivated based on root yield and effective medical components.
Proximate, Free Sugar, Amino Acid, Dietary Fiber and Saponin Composition of Agngelica Keiskei Koidz
Korean Journal of Plant Resources, volume 12, issue 1, 1999, Pages 31~37
To accept basic data of utilizing of Agngelica Keiskei Koidz as a raw material of industrial products, major chemical components were investigated. Comparing proximate composition of leaf and steam of Agngelica Keiskei, leaf contained higher crude protein, crude fat and crude ash, but lower moisture and crude fiber. The content of vitamin C in leaf and steam were 75mg% and 59mg%, respectively. The major free sugars were fructose and glucose and sucrose was also detected in a small amount. Total amino acid contents of leaf and steam were 1737.4mg%, 319.7mg%, respectively. Although the amino acid compositions of leaf and steam were different, threonine, histidine, leucine, glutamic acid and glycine were the major components. The major free amino acids were histidine, alanine, leucine, threonine and arginine, but were percent in a trace amount. The contents of total dietary fiber(TDF) in leaf and steam were 31.89 and 43.37% on dry basis, respectively. The content of saponin in leaf and steam were 535.51mg% and 463.09mg%, respectively.
Evaluation of Agronomic Characteristics Indigenous Germplasm for Development of High Quality and Yield of Ginger (Zingiber officinale Rosc.)
Korean Journal of Plant Resources, volume 12, issue 1, 1999, Pages 38~42
To obtained the basic information needed in the development of higher quality and yield of ginger, twenty-four indigenous colones of ginger were evaluated major agronomic characteristics under field and polyethylene house culture. There was highly significant differences in yield and 6-gingerol contents among the clones studied. Maximum yield was recorded in clone CG9579(3520kg/10a) followed by CG95134, CG9512, CG96109, CG9596, in field culture. The maximum 6-gingerol percentage was recorded in the clone CG9579 containing 4.44mg/g, and next was CG9583 4.35mg/g, CG95134 4.32mg/g DW. In addition, CG9503 and CG95105 clones showed more than 4,000kg/10a in polyethylene house culture.

Korean Journal of Plant Resources, volume 12, issue 1, 1999, Pages 43~49
To develope wild flower collected from Chollabuk-do area resource plant species were investigated from May 1996 to April 1997. This study was focussed to make the basic data for better quality of breeding species from wild flower species and to keep proper gene pool for development with competitive power internationally in future. There was 131 species blooming in spring season(34.7%), 219 species in summer(58.1%), 25 species in autumn(6.6%) and 2 species in winter(0.5%), respectively. Flower color of all the plants was 26 kinds in diverse, among them, white flowers were occupied dominantly of 28.9%, yellow flowers, 20.7%, violet flowers, 16.4% and red purple flowers, 7.9%, respectively. Transplanted wild flower plants at the garden in the study area frequently were Chelidonium majus var. asiaticum, Hemerocallis fulva, Iris nertschinskia, Rhododendron yedoense var. poukhanense, Rhododendron mucronulatum, Pulsatilla koreana, Chrysanthemum zawadskii var. latilobum, Taraxacum platycarpum, Chrysanthemum boreale, Liriope platyphylla and Lycoris radiata. Twenty-six species of wild flowers such as Cymbidium goeringii, H. fulva, L. radiata, C. zawadskii var. latilobum, etc. were collected from their habitat and being selling at the market or road side. Total 343 taxa of wild flowers to prevent carrying out to foreign countries and to improve better quality were selected and recommended in this study, for example, they were 41 taxa of Compositae plant, 25 of Rosaceae, 20 of Liliaceae and 18 of Ranunculaceae in order. Acorus calamus var. angustatus, Cypripedium japonicum, C. macranthum, Calanthe discolor, Dicentra spectabilis, Ilex cornuta, Stewartia koreana, Abeliophyllum distichum, Forsythia saxatilis and Campanula glomerata var. dahurica should be protected as wild flowers because their numbers are decreasing remarkably, belong to rare species, being at a crisis to extinct species and important plants for research materials.
Study on the leaf morphology of Korean Aster L. and its allied taxa
Korean Journal of Plant Resources, volume 12, issue 1, 1999, Pages 50~61
The leaf morphological and anatomical characters about 17 taxa of Aster and its allied taxa were investigated to estimate taxonomic values. Leaf shapes of the treated taxa were divided into five types; elliptic, spathulate, lanceolate, linear, ovatodeltoid. These types were fixed in same taxa, but variable among different taxa, therefore useful as taxonomic character. Leaf margins were divided into four types; entire, serrate, dentate, incised, these types were invariable in most taxa, but variable among individual in same taxa such as Kalimeris incise, Aster spathulifolius. The size and shape of leaf epidermal cell, the size and distributional numbers per 10
of stomata, deposit feature of cuticle were not distinguished clearly from treated taxa, but presence of stomata on adaxial surface, size and distributional numbers per 10
of stomata were useful taxonomic characters in some taxa such as Gymnaster koraiensis, Aster altaicus var. uchiyamae, Aster tripolium, Heteropappus arenarius. The leaf trichomes were divided into five types by basic form, sculpturing on their outer surface and cell arrangement; uniseriate granulate conical type, uniseriate psilate conical type, uniseriate psilate filiform type, globular type, biseriate vesicular capitate type. In spite of various habitat, basic morphology of trichomes were not changed, therefore, it was thought to be good taxonomic character.
