The effect of Cultivated Environments on the Antioxidant Enzyme Activities of Codonopsis lanceolata
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 203~210
The activities of the antioxidative enzymes in the roots of Codonopsis lanceolata have been compared depending on the cultivated environments - wildness, cultivate paddy fields and cultivate dry fields - and the parts of the root. In the Codonopsis lanceolata raised in cultivate paddy fields, the activity of SOD was higher in 2 yrs old than 1 yr old, but the activity in 1 yr old was higher than in 2 yrs old for the plants raised in the cultivate dry fields. The specific activity of SOD in wildness plants 86.069unit/mg protein was the highest among plants studied. The tissue distribution of the SOD activity showed differences depending on the enviroment. The highest activity of SOD was shown in the upper part of the root for the cultivate paddy fields, the loewr parts for the cultivate dry fields and middle parts for the wildness. The specific activity of POD was increased with ages of the plants, and that in the wildness was the highest 68 unit/mg protein among the plants studied. The activity of POD in the parts of the roots was shown as middle>lower>upper. The activity of POD in the middle part of the root, rasied in Soebick province was 85 unit/mg protein. The specific activity of CAT was decreased with ages of the plants. The activities of wildness and cultivate paddy fields was similar, but that in cultivate dry fields was lower than others. The tissue distribution in the parts of the roots was upper>lower>middle. The activity of CAT middle part of rasied in the Sebuck area was 5.359 unit/mg protein. The activities antioxidative in the cells cultured in MSID(Murashige and Skoog +2.4-D 1mg/
) was followings: 1564 for CAT. 30 for POD and 22200 unit/mg protein for SOD. These figures were lower than that in in vivo.
Fatty Acid and Amino Acid Compostions of Gugiseun (Lycuim chinense Miller) Depending on Variety and Harvest Time
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 211~217
As a part of studies on the development of a Gugisuen(Lycium chinense M.), which is one of the unutilization of waste resources, we investigated the composition of fatty acid and amino acid according as picking period and varieties of Gugisuen. The chemical components of Gugisuen were as follows : 1. Proximate composition of Gugisuen were Cheongyang native had the highest contents of crude lipid, crude protein, total sugar, and the contents of crude protein, total sugar, and reducing sugar was the highest picked on June 20. 2. The contents of
, CaO, MgO, Cu, and Mn were higher in Cheongyang native than that of other varieties. And mineral contents of Gugisuen picked on May 10 were the highest. 3. The major fatty acids were linoleic, linolenic acids, and these unsaturated fatty acids composed about 50% of total fatty acids. Fatty acid compositions between each varieties were not significant, and those components were the highest in Gugisuen picked on May 10. 4. Eighteen amino acids were identified from Gugisuen, glutamic acid, the highest content was
and these contents increased in the order to aspartic acid > glycine > alanine > leucine > lysine. The contents of serine, arginine, methionine, cystine-2 and isoleucine were higher in late harvest time and glutamic acid and tryptophane were higher in early harvest time.
Comparison of Chemical Components among varieties of Elephant-food (Amorphophallus konjac, K.)
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 218~223
This study was carried out to obtain a basic information for the improvement of human health and the development of variety through the analysis of inorganic compounds. contents of amino acids and polysaccarides on three elephant foods, Amorphophallus konjac, collected from Kumsan, Japan and China. The contents of mannan as a carbohydrate of a major component in an elephant food was slightly high in Kumsan than that of Japan and China variety. Degree of VIscosity of an elephant food depends upon the contents of soluble free sugars and amino acids contents of these free sugars were high in the order of Japan, China and Kumsan variety. The analytical results on inorganic compounds in an elephant food were shown as follows; The contents of potasium, phosphate and ferrin of Kumsan variety were shown to be higher than those of China and Japan, while sodium and caleium were appeared to be highter in China chip
Studies on the flavonoids of the Hibiscus syriacus L. Complex
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 224~229
Floral flavonoids of Hibiscus syriacus L. six complex with 68 formac all in all were examined. Thirteen flavonoids appeared on the two dimensional chromatogtams. Spot 5, however, occupied more than 50% in total flavonoid contents, and other spots were invariably minor pigments in all samples examined. Ten spots among 13 spots showed the characteristics of flavones, having color of purple to dark purple under UV light and yellow under ammonia gas, while spots reagents suggests that 10 purple spots are 4', 5-OH aglycone type. Four spots out of 10 purple spots were possible to be identified: spot 5, saponarin, spot 7, vitexin, spot 9, xylovitexin, and spot 11, rhamnosylvitexin, respectively. It was suggested that spot 13 might be apigenin-7-O-diglycoside.
Changes of General Components and Aromatic Constituents in Codonopsis lanceolata Grown at The Native and Cultivated Area
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 230~238
The experiment was carried out to find aromatic constituent composition of Codonopsis lanceolata species grown in the native(Mt. lrwol, Youngyang, Kyungpuk Province) and the cultivated(Andong, Kyungpuk Province) areas from 1994 to 1995. The results were as follows : Air temperature and soil temperature at the native area were lower to
, and to
than the cultivated area. Organic matter contents of plant grown at the native area higher than that of plants at the cultivated area by 4.8%. Crude protein content was higher in plant grown at native area than the plant grown in wild area but in case of crude saponin, plants grown at wild area was higher than that of native area. For inorganic element contents. K content is much higher than in the domesticated area as compared with wild area above ten over. And other elements such as Cu, Mn, Na and Mg were not remarkably different in contents. In the free amino acid compositions, argine was highest compared with other free amino acids, and Arginine content was higher in dometicated area. Recovery yield of essential oil of wild species grown at the cultivated showed 0.005%, but domesticated species was 0.004%. But both species at the native area were the same by 0.004%. Although composition of aromatic constituents in the two areas and species varied, total aromatic constituent was 21 kinds. Most aromatic constituents were aliphatic alcohols such as 1-hexanol, eis-3-hexanol, and trans-2-hexanol occupied by approximately 90% over. But three constituets as amylalcohol, furfuryl acetate, and 2-methoxy-4-vinyl phenol(MVP) were detected only in domesticated species.
Studies on seed germination by treatment of NaCl in rice
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 239~242
This experiment was conducted to utilize the basic information for salinity tolerance using Dongjinbyeo, Mangeumbyeo, Hwangkeumcheong, Nihonbare and Norin 29 as Japonica rices. Salinity level, 0.3, 0.6, 0.9, 1.2 and 1.5%, were treated and germination rate, recovering rate and radicle length of seeds were measured. The germination rate showed the range from 92 to 100% at the concentration of 0.6% of NaCl. However, it decreased at 0.9% and rapidly reduced at 1.2% above for all varieties. Recovering rate for salt damage of seeds was favored in Dongjinbyeo, Mangeumtyeo, Hwangkeumcheong about 92 to 98% after two days of transfering, but 73 to 76% in Nihonbare and Norin 29 were represented. The radicle length revealed shorter with decreased salinity level, particularly all varieties showed one centimeter less at the concentration of 1.2% above.
Effects of fertilizers and flowering position on the yield and quality of Black medik seeds(Medicago lupulina L.)
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 243~248
The yield and quality of black medick seeds(Medicago lupulina L.) produced from different fertilization and flowering position was investigated was investigated to develop the technology of seed vigor maintenance. Number of flowers and seeds, 100 seeds weight, yellow seed percentage, and large seed percentage were higher in seeds produced from stems than in those from branches. Increase of nitrogen resulted in a higher rate of yellow and large seeds as well as 160 seeds weight. Germination rate was the highest (56.9%) in the yellow seeds harvested from stems which were grown with a treatment of lower level of nitrogen and higher level of phosphorus. Malformed seedlings were frequently observed among the seedlings grown from seeds which were produced only with phosphorus.
The Effects of Trickle Irrigation Culture and Catch in the Rain on Seed Production of Onion
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 249~253
The study was conducted to investigate the effect of the culture with trickle with trickle irrigation in transparent vinyl house on the seed productivity of onion. Growth, number o tiller and leavers, plant height, leaf sheath length, flowering rate, diameter of flower wheel, number of little flower per flower stalk and fertilization rate are best in the case of the seed production under the culture with trickle irrigation in transparent vinyl mulching house, catch in the rain with vinyl from February to March, so it is found that it is appropriate to plant the onion mother bulb under the culture with trickle irrigation in transparent vinyl mulching house, catch in the rain with vinyl from February to March in the Southern areas of Korea.
Effects of Shading Net Treatment and Planting Density on Growth and Fresh Leaf Yield of Aster glehni
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 254~260
The study was conducted to find out the ways of increasing fresh leaf yield under conditions of the optimum shading net treatment and planting densities of Aster glehni. Although the most effective shading net treatment to acclimatize the plant was 75% shading in 1993, as growing years were prolonged, effects of shading net treatment was not recognized. Ca contents in 75% shading net treatment was much higher than other shading net treatments. Shading effect tend to promote their growth and fresh leaf yield in 1993 even though 75% shading net treatment did not increase fresh leaf yield in 1994 and 1995. Planting density.
. showed the effectiveness fresh leaf yield for 1994 and 1995 except for 1993.
Effects of Fertilizers on Growth and Yield of Tree Peony Moutan cortex RADICIS
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 261~267
This experiment was carried out to investigate the effects of various fertilizers on the growth and yield of tree peony Moutan cortex RADICIS from 1990 to 1994. The paeonol content, a main medical ingredient of tree peony, was 0.5% in the control, and the contents of the chemical fertilizer(N-P-K) and the two-kind compound fertilizer treatments were
, and those were lower than
of the compost, the fowl dropping manure and the organic fertilizer treatments. The weights off dry root(radix) rind were increased by 42% in the fowl dropping manure treatment and by 49% in the compost treatment compared with 151kg/10a in the control. All things considered, compost, fowl dropping manure and organic fertilizer were more effective than chemical fertilizers for the culture of tree peony.
Effects of Pinching times on Root Yield and Quality of Codonopsis lanceolata (S.et Z.) Trautv.
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 268~275
To produce edible Codonopsis shoots in spring, the effect of shoot pinching times on root yield and quality of Codonopsis was evaluated during 3 years from 1992 to 1994. Shoot growth decreased by increasing picking times and one time pinching of Codonopsis shoot was optimal for seed production. In case of 3 times shoots harvest per year. yield of edible Codonopsis shoots amounted to 29.5MT/ha for 3 years. Increase of shoot picking times exerted harmful effect on root growth and decreased marketable value of harvested shoots. It was recommended from the results. One-time pinching of shoot a year for the production of marketable shoots and roots after 3-year cultivation.
Effect of different fertilizer application on the dry matter production and leaf photosynthetic of Yacon(Polymnia sonchifolia)
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 274~278
This study was conducted to examine the dry matter production and leaf photosynthesis under different fertilizer application in Yacon(Polymnia sonchifolia)plants. Under field conditions, dry matter production of stable mature application plot(S-1) was much larger than non-treated control plot(CTL), but bulb dry weight of 10kg nitrogen application plot per 10a (N-10) was not differentiated from CTL. The maximum photosynthetic rates increased in Yacon plants grown at S-1 while in the rates of CTL reduced under glasshouse in the same treated pot condition. The optimum temperature for the highly photosynthetic rates is about
, and the rates did decrease by stomatal resistance below 28℃. The estimated light saturation point was
. The results of this study indicate that soil conditions were highly related to dry matter production and leaf photosynthesis rate in Yacon plants.
Culture Practice of Green shoot of Chinense Matrimony Vine (Lycium chinense Mill.) I. Effect of Varieties and Cutting lengths on the Growth and Green shoot Yield
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 279~284
Effects of varieties and cutting lengths of Chinense Martrimony Vine on the growth characteristics and the yield of green shoot were investigated in order to obtain the basic data The Yuseong-2 was observed higher in the number of green shoot per plant, of green shoot, but smaller in the length and the width of leaves than those of Cheongyang native. The number of green shoot was decreased in longer cutting length, but the other growth characteristics were increased. The dry weight of green shoot was
and the ratio of stem to leaf in green shoot was higher in leaf than that of stem, and the ratio was 46 : 54. The dry yield of green shoot was
in Cheongyang native and
Yuseong-2 and the dry yield of green shoot of Yuseong-2 may be expected in this planting year. Each growth characteristic of varieties was highly positive correlation with the yield except the number of green shoot of Cheongyang native. The number of green shoot of Yuseong-2 was nagative correlation with each growth characteristic and the yield except the number of total leaves per plant.
Variation of rachis branches in rice varieties with different maturing types by various planting times.
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 285~290
This experiment was conducted to investigate the variation of adhering primary and secondary rachis branches of panicle in three ecotypes at National Honam Agricultural Experiment Station in 1993. Three ecotypes. Odaebyeo and Sinunbongbyeo as early-maturing type, Cheongmyeongbyeo and Changanbyeo as medium, and Dongjinbyeo and Mangeumbyeo as late-maturing type were used. The treatment were 5 planting times from May 5 to 5 July by 15 day intervals. The number of primary rachis branch in early maturing type recorded high in between May 5 and 20 May as early transplanting. Medium and late-maturing type, however, was found to be have more primary rachis branches at the late time of June 20 transplanting than at the optimum transplanting of Honam area. The number of secondary rachis branch was high between June 5 and 20 June regardless ecotypes. The rate of secondary rachis branch per primary rachis branch was increased with later transplanting time up to June 5, but showed no differences onwards. The number of grain in primary and secondary rachis branches were low in transplanting time of May 5 regardless ecotype but high in late transplanting time by July 5. Densinty of seed sets was found to be higher in late transplanting than in early transplating;early-maturing type showed high in July 5 and 20 June in medium-late maturing type respectively.
Notes on the Korean Ascomycetes (I)
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 291~297
Many Ascomycetes of higher fungi were collected at Mt.Jiri National Park and Mt.Moak Provincial Park from March 1995 to September 1996. They were identified by the keys of Dennis(1981) and Breitenbach and Kranzlin(1984). Of these, Hypoxylon multiforme, H. rubiginosum, H.udum, H.rutilum, Nectria gallignea, N. coccillea, N. pallidula, and N. fumicola were recorded as new to Korea.
Fruit Wall Anatomy of Ocotea (Lauraceae)
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 298~304
The fruit wall anatomy of Ocotea was investigated on the basis of 14 species within the genus to contribute to a better understanding of specific relationships and homogeneity of genus. The species have a similar mature fruit wall structure, but diUerences among the species are found with respect to whether or not sdc.nchyma cells are present in the mesocarp. if present, whether or not they are present in particular positions and forms. Comparisons with species studied suggested that at least a few groups of species can be distinguished in Ocotea. They arc divided into five groups on the basis of anatomical structures. i.e., group 1) O. atrriensis, O. cujumari, O. helicterifolia, O. rubra and O. schomburgkiana; group 2) O. aeiphylla, O. javitensis, and O. sp. [Werff et ai. 12676]; group 3) O. tonduzii: group 4) O. foetens, O. quixos, and O. veraguensis; and group 5) O. floribunda and O. nitida. These various variations in Ocntea were also discussed to invite its respective systematic revisions. By the comparisons with species, on the other hand, it suggested that the specialized species are evolved from non-specialized species.
Comparative studies of the five edible mountain vegetables by DNA marker fingerprinting
Korean Journal of Plant Resources, volume 9, issue 3, 1996, Pages 305~310
Five edible mountain vegetables(Saussurea sp. Aster tataricus, A. scaber. Synurus deltoides, Ligularia fischeri) were investigated on the basis of amplified DNA polymorphisms resulted from PCR (polymerase chain reaction) analysis. The sampled plants consisted of 38 individuals in 5 taxa. Only 10 primers out of 62 primers (60 random [10-mer] primers, two 15-mer [M13 core sequence, and (GGAT) sequence]) tested gave rise to polymorphisms in all of the tested plants, producing 176 DAN fragments amplified. Intraspecific polymorphisms found in each taxa showed intraspecies constancy (31.1-61.1%) in the banding patterns of individual plants: Saussurea sp. 31.1%, 15 bands, Aster tataricus, 40.9%, 18 bands, A. scaber. 38.5%, 15 bands. Synurus deltoides, 34.7%, 17 bands, and Ligularia fischeri, 61.1%, 22 brands, respectively. All five species were well classified from each other at the 0.93 level of similarity index value. Intraspecific and interspecific variations were appeared at the levels ranging from 0.62 to 0.99. Based on these results, our PCR analyses support the previous data derived from external morphology of the 5 edible mountain vegetables, but very low levels o intraspecific variations were detected in all of these taxa.
