Distribution and Status of the Big and Old Trees as Plant Genetic Resources in Ansung City
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 99~108
This study was carried out to make a standard criteria for protection and maintenance of the big and old trees in Ansung city, Kyonggi Prvince. There have been found 6 vegetative species cultivated in this area, which are Zelkova serrata, Gingko biloba, Kalopanax pictus, Pyrus ussuriensis var. macrostipes, Pyrus ussuriensis var. acidula, Pinus densiflora, etc. The Zelkova serrata tree is the major species among them and about 73.5％ in the population of the big and old trees in this area. The DBH (diameter at brest height) of them is 1.5-1.9m in 29.4% of whole population and the tree height is 10-l4m in 47.1%. The estimate age of 7 trees is more than 500 years old and they were 20.6％ of the whole population. Interesting point is that about 64.7％ of these trees in this area have own succeed story in terms of folk religion, object of worship, taboo, legend or secret. This study has also revealed that many fowls, small animals and epiphyte inhabited with the big and old trees have been found. However, 97.1％ of them are in danger from the plant disease and noxious insects or cutting damage of branches, but no management has been taken. More over, 85.3％ of the whole investigated big and old trees have been in the poor condition for percolation or aeration because the area around them has been payed with asphalt or concrete.
Chemical Components and Comparison of Biological Activities on the Fruit of Natural Bogbunja (Rubus coreanus Miquel)
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 109~117
This study was carried out to investigate biological and antioxidative activities on the fruit of bogbunja (Rubus coreanus Miquel). Total contents of phenolic compounds contents in cultivars ripened fruit and immatured wild-type fruit were 222 and 190mg/g, respectively, Polysaccharide contents of immatured wild-type fruit were the highest value of 320U. For EDA analysis, immatured wild-type fruit showed over 95％ in 100
/mL of sample concentration, which is the the most effective. Levels of SOD-like activities in immatured and cultivar ripened fruits were 81％ and 77%, respectively, For the inhibitory effect on lipid peroxidation, all of bogbunja prepared were similar with those of
-tocopherol as control. The inhibition of ACE activities on the water extracts of bogbunja fruit showed over 98%, especially, in immature wild-type and cultivar bogbunja.
Effects of Black Polyethylene Film Mulching and Planting Density on Growth and Yield of Rehmannia glutinosa Libosch.
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 118~122
These studies were carried out to clarify the effects of black P.E. mulching and planting density on the growth and rhizome yield of Jihwang #1, a new high yielding Rehmannia glutinosa variety. Emergence ratio was higher 3.1％ in mulching than in non-mulching, but was not affected by planting density. Plant height and fresh leaf weight per plant were increased by mulching and at lower planting density. However, the fresh leaf weight per unit area was increased at higher planting density. Dry rhizome weight was increased 28% in mulching than that of non-mulching. Dry rhizome weight per plant was increased, but that of per unit area was decreased at lower planting density.
Oil Content and Growth Characteristics of Collected Safflower varieties
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 123~129
This study was conducted to determine the germination characteristics, oil contents and fatty acid compositions of the different safflower accessions. The safflower accessions had nearly the same germination period of about 12-13 days and the germination rate was more than 87.5%. Plant height grew until 84 days after seeding. The number of leaves did not increase after 70 days from seeding. The accessions had a difference of six loaves from 17 to 23 loaves. Flowering time had a difference of 11 days from 79 days after planting to 90 days after planting. The Jangsung accession had the shortest flowering time of 79 days after planting. In the characteristics of bearing fruit, the number of branches including main stem are from 4.7 to 8.8. The number of head flowers had nearly the same number of branches which were 4.8-8.9, numbers of seed per head flower were 29.3-49.1 and the weight of 100 seeds were 2.9-3.9 g. The crude fat content was 21.8-33.9％ and fatty acid content was 66.6-77.6% containing mostly linolenic acid. Oeic acid content was 9.2-16.5% and it contained palmitic acid, stearic acid, venin acid, arachidonic acid etc. Results of this study, the accession Jangsung, which had the shortest flowering time and had the most crude fat content, was observed to be the best accession for the breeding of safflower.
The Effect of Activated Charcoal on Growth and Yield in Bupleurum falcatum
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 130~133
This study was conducted to investigate the effect of activated charcoal on growth and yield of taro in different degree of activated charcoal concentration. The results obtained are summarized as follows. Stem length was shown the longest in activated charcoal of 10-20％, but shorter in control. Also stem diameter was shown the thickest in activated charcoal of 10-20%, but thinner in control. Length of main root and thickness of main root were good in activated charcoal of 10-20%. Quality and yield of Bupleurum fatcatum was the highest in activated charcoal of 10-20%. Therefore, optimum consistency of activated charcoal was 10-20%.
Studies on the Cropping System of Perilla in Middle Provinces of Korea
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 134~140
To increase self-sufficiency ratio and agricultural income, six cropping systems by introducing several crops in perilla were tested from 2001 and 2002. Weed occurrence was high in barley+perilla and safflower+perilla cropping system. Pre-and post-crops in barley+perilla and safflower+perilla showed good growth. Safflower+perilla cropping system was labor-saying and cost down because polyethylene film of pre-crop was reused in post-crop. But when perilla was introduced as post-crop of sesame, delayed seed date resulted in decreased growth and grain yield. The income in barley+perilla and safflower+perilla was greater 4.1fold and 5.2fold, respectively than in perilla mono-crop system. Soil physical properties were improved in order of safflower+perilla, barley+perilla cropping system.
Effects of Seed Pre-treatment on Field Germination of Zanthoxylum piperitum DC.
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 141~146
To improve the percentage of field germination of Zanthoxytum piperitum DC., storage in ground(control) and several chemicals as treatments was investigated. Germination percentage was 30.3 and 22.7% in GA
(100 ppm) and NaCIO(10%), respectively compared with 17.3％ in storage in ground without treatments. Germination percentage reached maximum between 26 and 33 days after seeding and then increased slowly. Top/Root ratio was the highest at storage in ground after the treatment of GA
Agronomic characters of Korean Adzuki Beans (Vigna angularis (Willd.) Ohwi & Ohashi)
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 147~154
Agronomic characters of the 361 Korean adzuki beans(Vigna angularis (Willd.) Ohwi & Ohashi) collected in Korea were examined. Korean adzuki beans had predominantly up right growth habit types, followed by the intermediate types (15.3%) and the climbing types (6.9%). Round leaf type was the majority among the collections and followed by elliptical and xiphoid leaf type. Adzuki beans with yellow, light yellow and dark yellow flowers were 89.5％, 9.4％ and 1.1％, respectively. The 60.6% of the collections had red seeds and 26.9% had gray seeds. And collections with green seeds, white seeds mixed with gray spot, brown spots on red seeds, black spots on red seeds and dark gray spots on black seeds were also observed. Korean adzuki beans whose number of days from planting to flowering were 69∼75 days were the majority among 361 Korean adzuki beans. The number of days from flowering to majority were 41∼50 days and the number of days from planting to maturity were 111-120days. Adzuki beans having the stem length of 41-60 cm, the pod number per plant of 16-20 and the 100 seed weight of 8∼10 g were 50.2％, 40.2% and 30.5％ of collections, respectively.
Agronomic Characters of Local Perilla Collected in the Southern Part of Korea
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 155~159
This study was conducted to examine the variations in 196 local perilla collected in southern part of Korea and to provide basic informations which can be utilize in perilla breeding programs. The results obtained were gummarized as the follows. Maturing period was widely distributed from 104 to 136 days. The maturing periods of most collections were 111 to 130 days(96%). and that Four percent of collections showed maturing period of below 110 days and above 131 days. Three varieties below 111 days of maturing period were selected among local perilla collected from Jeonnam(Naju and Boseong) and Jeonbuk(Gochang). Stem length was ranged from 71 to 157 cm. The stem length of 111 to 130 cm, under 90 cm, and above 151 cm were 41％,, 7％, and 4％, respectively. Seven varieties with long stem were selected among local perilla collected in Jeonnam(include Damyang collection). The number of cluster per plant was distributed 52 to 291. The distribution of cluster numbers were 100 to 180, under 100, and above 221 was 57％, 13% , and 13%, respectively. The number of seed capsules was distributed 23 to 56 and the collections ranged from at of 26 to 45 was 49.5％. Seed cluster length was distributed from 6 to 20 cm and that ranged from 8 to 14 cm was 62.8%.1,000 grain weight ranged from 2.4 to 5.7 g. The distribution of 1,000 grain weight is 3.1 to 4.0 g,4.1 to 5.0 g, and below 2.9 g was 66.8%, 12.8%, and 19.4%, respectively. The 1,000 grain weight above 5.1 g(1.0%) was selected among local perilla collected in Jeonbuk(Namwon) and Gyeongnam(Changnyeong).
Mass Production of Calla Lily(Zantedeschia spp. Southern Light) by the Immature Zygotic Embryo Culture
Korean Journal of Plant Resources, volume 16, issue 2, 2003, Pages 160~167
In order to investigate the effects of developmental stage of embryos and plant growth regulators on mass production of Zantedeschia spp. Southern Light, immature zygotic embryos of Zantedeschia spp. Southern Light were cultured on Murashige and Skoog(1962) basal media or containing 2,4-D, NAA and BA. Globular embryos did not grow on any of the 2,4-D, NAA and BA combinations. The most suitable stage of immature zygotic embryo culture on the induction callus and multiple shoot was at early cotyledonary embryo stage, and at this stage of embryos were germinated up to 87.5%. The whitish watery callus and yellowish compact nodular callus produced on all 2,4-D, NAA and BA media. The best combination for inducing embryogenic callus was 0.5 mgL NAA and 1.0 mg/L BA. Whitish watery calli have been subcultured for more than 8 months and have retained their producing ability, Plant regeneration was only obtained by direct shoot development and yellowish compact nodular calli. Abundant plantlets were regenerated from cotyledonary stage of embryo culture on MS medium supplemented with 0.5 mg/L NAA and 1.0 mg/L BA. Supplementation of the media with 10％ coconut water showed as the best concentration for plant differentiation from direct developed of shoots. The number of regenerated plants from one embryo could be seperated 25-35s plantlets. All yellowish compact callus-derived plantlets were transferred to pots containing a mixture of vermiculite, perlite and sand(1:1;1 v/v) and 100% of divided plantlets were phenotypically normal.
