Flowering Season and Flower Color of the Alpine Plants in Paeknokdam, the Crater of Mt. Halla
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 1~7
Life form, flower color, flowering and seed-ripening seasons of 59 alpine plants in Paeknokdam, the crater of Mt. Halla, were investigated in order to obtain the information about ornamental potentials of alpine plants. Life form spectrum of alpine plants are characterized by a high percentage of hemicryptophytes (67.8%). This result was similar to those of other alpine plant communities. Flowering season of alpine plants was July to August and seed-ripening season was August to September. Flower color of these alpine plants was dominated by white (27%), blue (22%) and yellow (20.3%).
Effect of Sterols on Phytophthora infestans and Oospore Production on detached Potato Plants
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 8~14
The effects of media, cholesterol,
-sitosterol and lecithin on the growth and oospore production of the isolates KM10, U6, CDB6, MHB6, JD1 (A
type) of Phytophthora infestans isolated in Korea and F8l7, DNC303 (A
type), IB908, DN107 (A
type) obtained from Japan were investigated. Mycelium of P. infestans grew better on V-8 juice agar and rye meal agar than on the other media. Oospores were produced most abundantly on V-8 juice agar. Mycelium extended more 16.6, 8.3, and 5.2% on V-8 juice agar supplemented with 5
-sitosterol and lecithin, respectively, and oospores are produced 76.0, 58.0, and 34.6 % on V-8juice agar supplemented with 5
-sitosterol and lecithin, respectively. Oospores more produced on detached potato plant disks when
type exist simultaneously which indicating that variation of population can occur in the field, but the rate of oospore formation and the number of oospores produced was low and small quantity.
Shooting and Seedling Characteristics according to Growth Regulators, Length and Diameter of Scion in Root Cuttings of Lacquer Tree (Rhus verniciflua)
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 15~23
Effects of growth regulators, scion length and scion diameter on shooting and seedling characteristics were investigated to increase seedling products by root cuttings of lacquer tree. Shoots developed and emerged above-ground from the root scion at 3∼5 weeks after cut plating, most of that was a shoot but some of that were 2∼3 shoots. Otherwise, non-shooting was the reason that cortical layer was decayed. Soaking in zeatin was the most effective on shooting of root cuttings and high concentration was effective. Also soaking on high contents of BA or kinetin was effective on shooting but was lower totally than soaking on zeatin. Seedling characteristics among 3 growth regulators and 3 concentrations were not any difference in statistical significant, but were move excellent than control. As root scion was tall, shoots were developed at early. 15cm length scion was the most excellent to use seedlings but 3cm length scion was wickedness. 10cm scion, however, was highest to product of seedlings than any others. 0.3∼0.5 cm length scion was showed 76% shooting rate at 10 weeks after cut planting, but seedling characteristics were not any difference among the kind of 3 diameters.
Comparison on the Phthalides content of Cinidil Rhizoma and Angelicae Radix cultivated in Korea and China
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 24~31
The medicinal constituents contained in Cinidil Rhizoma and Angelicae Radix cultivated in Korea and China, were compared by confirming their qualities. From Cinidil Rhizoma and Angelicae Radix cultivated in Korea and China, butyl phthalide, senkyunolide, and ligustilide etc. phthalides were identified by GC/CMS analysis. Through GC/FID analysis, the senkyunolide content of Cinidil Rhizoma cultivated in Korea was similar to that cultivated in China. The ligustilide content of Ciniail Rhizoma cultivated in Korea was more than that cultivated in China, except for one cultivated at Ankuk province. In the case of Angelicae Radix, the ligustilide content of that cultivated in Korea was more than one cultivated at Yeungil province in China. As for quality, Cinidil Rhizoma and Angelicae Radix cultivated in Korea were better than those cultivated in China since Chinese products possessed more butilidene phthalide photo-decomposed from ligustilide, caused by long storage during the circulation processes, than that of the domestic products.
Screeing of Tyrosinase Inhibitors from Oriental Herbs
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 32~37
Mammalian tyrosinase plays an important role in the process of melanin polymer biosynthesis by catalyzing the hydroxylation of tyrosine to 3,4-dihydroxyphenylalanine(DOPA) and the oxidation of DOPA to dopaquinone. These processes are major determinant of human skin color and involved in localized hyperpigmentation. Therefore, the enzyme inhibitors have been of great concern as skin-whitening cosmetics. Methanol extracts of 174 oriental herbs were screened for the mushroom tyrosinase inhibitory activity.
Effects of Plant Growth Regulator on Seedling Growth in Onion Seed(Allium cepa L.)
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 38~42
This study was conducted to stable direct sowing cultivation with seedling growth promotion by plant growth regulator treatment in onion seed(Allium cepa L.) The emergence percentage of soaked seed in BA, GA
, and kinetin solution were higher than control seed, and those were 93.0, 94.3, 93.8%, respectively. The plant height was significant elongation in growth regulators treated seed, and those effects were high GA
, kinetin and BA in the order, and the extend were high as increasing the growth regulator solution concentration in GA
and BA, and that was reverse in kinetin. The No. of leaf was increased in growth regulators treated seed, and the extend were similar among the growth regulators. The No. of root was increased significantly in growth regulators treated seed, and the extend were high in GA
, BA and kinetin in the order.
Effect of amount of fertilizer and defoliation on dry weight matter in sweet potato
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 43~47
For the purpose of sweet potato varietal improvement, yulmi, shinyulmi, gunmi, hongmi and seonmi, whose source and sink are different one another, were cultivated at different amount of fertilizers, and then defoliation at initial stage of tuberous root weight increase on the relation of source and sink was observed as follows. The response of stem, leaf and tuberous root weight by amount of fertilizer and defoliation rate of sweet potato varieties was different. Stem and leaf weight increased along with heavy dressing by the following order; shinyulmi> seonmi> hongmi> gunmi> yulmi. Tuberous root number was the most at
amount of fertilizer, showing seonmi the most number. The number of stem, leaf and tuberous root increased along with the lowered rate of defoliation. In case of
amount of fertilizer, tuberous root weight increased by increase of stem and leaf weight up to 50% defoliation and the difference of stem, leaf and tuberous root number was low as defoliation rate increases. The total dry weight matter was the most at heavy dressing amount of fertilizer.
Effect of Irrigation Treatment on Growth and Yield of Paeonia lactiflora Pallas L.(Peony)
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 48~52
The study was conducted to find effect of irrigation treatment during growth stage on growth and yield of Paeonia lactiflora Pallas L.. In case of top ground part, growth of irrigation treatment at early growing stage(from May 1 to June 12) was larger(stem length of 79.4cm) or thicker(stem diameter of 6.5mm) than stem length of 13.6∼7.4cm and stem diameter of 0.5mm of natural plot and control. The growth of under ground part, root length(34.0cm) and number of root/plant(43.6ea/plant) in irrigation treatment at early growing stage were relatively larger or more number than that of control, and root yield was gained 2,349kg/10a and increased 13% and 8% compare with natural plot and control, respectively. Commercial ratio of root was higher for irrigation treatment at early growing stage, it was increased by 20% than 1,708kg/10a of natural plot.
Seed Germination and Softwood Cutting Technique of Kalopanax pictus Nakai
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 53~59
This study was carried out to investigate mass propagation technique by using seed and vegetative propagation of Kalopanax pictus Nakai. For developing seed propagation, seed stratification and 1
after-ripening treatment induced embryo growth within 1 weeks, resulted in increasing germination rate of seeds up to more than 65% when planted. The softwood cutting using one year old shoot increased rooting rate to 69% whereas more than 1 year old shoot looked like inappropriate for cutting propagation. In the cutting timing, the rooting rate on June, 13 cutting of the first growth shoot was the highest, followed by June 20 and July 4. The most efficient cutting timing seemed to be the middle of June. When cutted shoots were soaked for 30 minute with IBA and NAA 1000mg.
, rooting rate was increased above 70%. As the concentrations of plant hormone were increased above 2000mg.
, the rooting rate was slowly decreased.
The effect of Sowing Dates on Major Agronomic Characteristics of Dendropanax morbifera
in Southern Area of Korea
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 60~64
This study was carried out to investigate effects of sowing dates and method on major agronomic characteristics of Dendropanax morbifera
. in southern area of Korea. The number of days from sowing to emergence was recognized liner negative correlation between sowing days. Dendropanax morbifera was sowed at seven different dates(from Dec.20 to Feb.20 at 30 days interval, from Mar, 1 to Apr. 15 at 15 days interval) in pot culture. In sowing date at Mar. 15, germination rate and early growth were good in pot. Dendropanax morbifera was sowed at five different dates(from Dec.20 to Apr.15 at 15 days interval) in field culture. In sowing date at Apr.15, germination rate and early growth were good in field culture.
Optimum Condition of Polymerase Chain Reaction Techniques for Randomly Amplified Polymorphic DNA of Strawberry
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 65~70
This study was performed to select marker which can identify genetic variation between mother plant and in vitro cultured plantlets of strawberry by PCR using random primer. When 'Yeobong' DNA extracted was treated with proteinase-K and RNase-H, clear DNA bands were shown. The optimal condition for RAPD in strawberry was to use 50ng of template DNA, 10pmol of primer,37oC of annealing temperature, and 45 cycles of PCR. After establishing above PCR optimal condition, RAPD pattern was investigated by using UBC primers. PCR was performed, and 46 of 90 primers produced PCR product showing 158 total bands. GC content was compared between the primers forming bands and no bands. The GC content showing bands was average 67.4%, whereas primers showing no bands 58%.

Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 71~76
This experiment was conducted to investigate the effect of the mechanized and intergrated working system on the reduction of time and expenditure for job's tears (Coix lachryma-jobi L.) cultivation. Emergence rate of working system was 50% at the merchanized and 62% at the conventional. Total working time was 230 minutes/10a at the merchanized and 2,273 minutes/10a at the conventional. Expenditure was 111,061 won/10a at the merchanized and 189,781 won/10a at the conventional. Date of emergence, budding, and flowering were the same for two systems. Growth characteristics were similiar in two systems, corn borer rate was 3.0% at the merchanized and 13.3% at the conventional. Grain yield components was higher at the merchanized than at the conventional. Thereby, grain yield was 351 kg/10a at the merchanized and 309 kg/10a at the conventional.
Survey on the Farms in Main Producing Area of Job's Tears
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 77~83
This survey was carried out to collect the basic informations for the improvement of cultivation in job's tears (Coix lachryma-jobi L.) by investigating the general facts, farming practices, growth characteristics, grain yield, and chemical properties of soil in Yonchon-gun farms. The age of farmers were over 51 and the cultivated area was small. Most farmers were self-laboring and produced seeds on their land. Sowing method was usually drilling by hand, 64% of farms had the density of 2000-3500 plant per 10 a, amount of fertilizer application was diverse and the number of pest control was a few. The averages of plant height, number of main culm node, culm diameter, tiller number of plant, thousand grain weight, and grain yield were 184 cm, 10, 10 mm, 14, 108 g, and 341 kg/10a, respectively. The averages of pH, organic matter,
, K, and EC of soil after harvest were 5.8, 1.1 g/kg, 385 mg/kg, 0.48 cmol+/kg, and 0.21 dS/m, respectively. Grain yield and hardness were negatively correlated -0.7442 at the level of P=0.01.
Effect of Application on the Growth of Head Lettuce under Fertigation Conditions in Highland
Korean Journal of Plant Resources, volume 14, issue 1, 2001, Pages 84~88
The growth of leaves in field-grown head lettuce(cv. Urake) was compared after conventional application of N-P-K fertilizer or after application of various dilutions of livestock waste solution. Plants treated with livestock waste solution diluted 25 times (Ef. 25) or 50 times (Ef. 50) had greater growth than that for any other treatment. The number of leaves was greater with Ef. 25 than that with other treatments, although the increase was not statistically significant. Total head yield increased by fertigation with livestock waste solution compared to yield resulting from conventional fertilization. Plant tissue weight was increased according to the increase in concentration of applied livestock waste solution. The soil chemical properties, pH, electrical conductivity,
-N, available P exchangeable Ca and Mg, all increased with the increased application of livestock waste solution. In conclusion, fertigation of the dilute livestock waste solution on the range of Ef. 25 to Ef. 50 could improve yield and quality in head lettuce.
