A Study on Determining Chemical Compositions of Schizandra chinensis
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 1~7
The results from the determination of contents of chemical components in Schizandra chinensis are as follows. The contents of malic acid and citric acid in Schizandra chinensis was 38,691 and 3,330 ppm/100g dry weight. The contents of total phenolic compounds in Schizandra chinensis was 1.560%. The predominat phenolic acids were cinnamic acid, gentisic acid, coumalic acid, chlorogenic acid and ferulic acid. Contents of crude lipids in Schizandra chinensis. was 160.5mg/g. Most of fatty acids in lipids were oleic acid, linoleic acid and linolenic acid which are unsaturated fatty acids, and palmitic acid which is saturated fatty acid. In case of essential oils, the predominat components in Schizandra chinensis were caryophyllene, calarene, cubebene, acoradiene and
Adventitious Bud Formation and Mass Propagation by Root and Propagation Medium of Wild Polygonatum odoratum Druce
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 8~17
To improve new propagation method, I try to propagate wild polygonatum odoratum roots which formate adventitious bud without bud. The obtained results of size of roots and adventitious bud to formate for multiple propagation of wild polygonatum odoratum as the follow. One year grown wild polygonatum odoratum root in 5cm diameter formate 66.5％ adventitious buds. One year grown wild polygonatum odoratum root in 15cm in diameter germinate 113% adventitious bud. Two years grown root in 15cm diameter formate adventitious bud three times more then one year root. Wild polygonatum odoratum in 15cm diameter without any bud in experiment plot makes 4 times of propagation. Sand and Perlite media propagaton plot was increased 3.1∼3.3times more than common culture medium. The best result of mass propagation wild polygonatum odoratum is 10mm diameter root and 5cm cut in length to plant sand media plot.
Germination Characteristics of PEG Priming Seed in Barley (Hordeum vulgare L.)
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 18~25
These experiments were conducted to evaluate the variability of seed germination, and seedling growth of PEG priming barley. The average germination percentage(AGP) of PEG priming seed was higher than control, but those were low with extend the treatment period. The AGP of washing seed after PEG priming was higher than unwashed seed, and that of redried seed after priming was lower than control. The germination time of priming seed was short compare to control seed, and that was prolonged with extend the priming period, and that of washing seed after priming was shortening, and that of redried seed after priming was prolonging. The emergence percentage(EP) of priming seed was higher than control, and the emergence time was shortest in 50％ field moisture capacity soil. The seedling and root length of priming seed was shorter than control.
A taxonomic study of Abeliophyllum Nakai (O1eaceae) based on RAPD analysis
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 26~35
Abeliophyllum distichum Nakai (O1eaceae) is a monotype of Korea and is distinguished from related genus Forsythia Vahl by the morphological characters such as fruit shape, flower color and etc. Even though several intraspecific taxa were reported according to the color of flowers and shape of fruits, there have been many controversals on the taxonomic indentity and status of rank on those taxa. In the present study, we performed the RAPD analysis to delimit the infraspecific taxa of Abeliophyllum distichum and to investigate the genetic polymorphism and relationships among 12 populations. 212 scorable RAPD markers with 70 common markers were found from the PCR reactions with 16 random oligoprimers and were analyzed by Nei's genetic distance. From 0.108 to 0.321 of genetic variations were showed among the taxa. Some regional groups instead of same taxa were clustered from the phonogram of UPGMA analysis. Also, we could not find distinct lineage among intraspecific taxa. The result from RAPD analysis supported that the infraspecific taxa of Abeliophyllum distichum might be the individual variations and treated as the same taxa. RAPD analysis was very useful to confirm the high gene pool with diverse genetic polymorphism among Abeliophyllum distichum populations.
Variation analysis of Atractylodes japonica Koidzumi ex Kitamura Based on Quantitative Characters
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 36~42
Sixteen Atractylodes japonica Koidz. accessions were collected in Jeonbuk, Kyeongnam, Kangwon and Kyeonggi province, and their quantitative characteristics were compared with each other. The relationship of variation between Atractylodes japonica Koidz. accessions was also investigated by means of multivariate analysis. Hamyang 1 accession had the most desirable quantitative characteristics among the accessions: plant height was 86.2cm, number of leaves, 117.2 and number of stems, 34.3. Sudo 1 accession had 12 stems, the most among the accessions. The length of leaf margin serras found in all of them was on average 1.6mm. Most accessions had simple or palmately compound leaf with oval or elliptical type of the leaf shape. The accessions could be classified into three groups by average linkage cluster method. The most remote relationship was found between Group 1 containing Jinan 1, Jinan 2 and Group 3 containing Jeongsu, and Geoje.
Effects of BA Treatment and Cut Planting in Root Cuttings of Lacquer Tree (Rhus verniciflua Stokes)
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 43~49
Effects of BA treatment and cut planting methods on shooting and seedling characteristics were investigated to increase seedling products by cuttings of lacquer tree. Dipping on 1,000mg/L BA solution was better than dripping with same solution at 5 weeks after cut planting. As shooting rate was increased suddenly, it was 85％ at 10 weeks after cut planting. Among 3 dripping treatments, interval was not effective on shooting rate. Dripping per 2 days with 100 ㎕ of 1,000 mg/L BA solution was most effective on seedling height and leaf number and than dipping was more effective than dripping per 5 and 7 days. Branch developed on near part from dripped scion. Shooting of horizontal planting was earlier about a week and rate was increased suddenly from 3 to 6 weeks, it was highest with 96％ than others at 10 weeks after planting. Seedling of horizontal cut planting was tallest about 40cm and branch developed lower than vertical and oblique cut planting. In case of horizontal cut planting, 2-3 shoots were formed on different part of scion and than those were could divided to seedling, so horizontal cut planting was most effective to propagation of seedling than any others.
A Study on the Fertigation of Swine Liquid Manure for Broccoli and Celely Western Vegetables
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 50~56
This study was carried out to optimize the fertigation method using fermented swine liquid manure for the growth of two western vegetables, broccoli and celery. Plants were grown in a rain-shelter house and fertilized with a range of dilutions(efflux 5 dilution=Ef. 5, efflux 10 dilution=Ef. 10, efflux 25 dilution=Ef. 25, and efflux 50 dilution=Ef. 50) of the liquid manure or with conventional application of N : P
5/ : K
O = 200 : 70 : 500kg/ha for broccoli, 250 : 210 : 240 kg/ha for celery as controls. After harvest, soil pH and K content decreased after using a high concentration of the liquid manure, Ef. 5, than after treatment with weaker concentrations at Ef. 25 and Ef. 50. On the other hand, soil electrical conductivity, content of P
5/, organic matter, total nitrogen, and NO
-N at Ef. 5 increased as concentration of swine liquid manure increased. After harvest, available P
5/ in plant tissue did not differ significantly between any of the treatments. In broccoli, the lower concentration (Ef. 50) of swine liquid manure increased flowering over the other treatments, perhaps because the level of absorption into the plants is higher with lower concentration. The amounts of K and Ca in plant tissue were greatest after Ef. 25 and Ef. 50 treatments. Plant growth was best at Ef. 50 in broccoli, head height, head width, and head weight were the best with Ef. 25 and Ef. 50 treatments after harvest. In celery, leaf length was greater after Ef. 25 and Ef. 50 treatments than any other treatments. Total yield of celery of Ef. 25 and Ef. 50 treatments was twice that of conventional cultivation. On the other hand, yield severely decreased after application of high-concentration treatment at Ef. 5. In conclusion, fertigation of swine liquid manure, diluted in the range of Ef. 25 to Ef. 50, could improve yield and quality in broccoli and celery.
The Effect of Activated Charcoal on Growth and Yield of Medicinal Plants
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 57~61
This study was conducted to investigate the effect of activated charcoal on growth and yield of medicinal plants in different degree of activated charcoal concentration. The results obtained are summarized as follows. Stem length was shown the longest in activated charcoal of 20%, but shorter in control. Also stem diameter was shown the thickest in activated charcoal of 20%, but thinner in control. Length and thickness of main root and thickness of main root were good in activated charcoal of 20%. Quality and yield of medicinal plants were the highest in activated charcoal of 20%. Therefore, optimum consistency of activated charcoal was 20%.
Effect of Seeding Date on Growth and Grain Yield of Perilla in Middle Area of Korea
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 62~66
To investigate the critical seeding date for Daeyeupdlkkae in the middle area of Korea, we seeded from 30 April to 20 July with 20-day intervals on the experimental field in Chungbuk-Do agricultural research and extension service. As seeding date was delayed, days to emergence were shortened, flowering and maturing date were delayed, but maturing period was not significantly affected by seeding date. Delayed seed date resulted in decreased stem length, culm diameter, number of branches per plant and number of nodes on the main stem. Cluster length and 1,000 grain weight increased but number of cluster per plant and number of seed capsules per cluster decreased with delayed seeding. Seeding date up to 10 June showed no effected on grain yield, but 30 June and 20 July decreased 10% and 38%, respectively.
Determination on optimum levels of three major fertilizers for Saururus chinensis Baill.
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 67~71
In order to determine the optimum level of three major fertilizers for Saururus chinensis, we applied to the soil at a rate of N(0, 4, 7, 10kg/10a), P
5/(0, 1.5, 3, 4.5kg/10a) and K
O(0, 3, 6, 9kg/10a) prior to seeding. Regarding physical properties after the application, the values of pH, OM, Mg, CEC and EC were higher than those of the pre-application, but the contents of P
5/, K and Ca were lower. With application of three major fertilizers, dry weight of leaves per 10a was 26∼108kg greater than that of control(281kg) and dry weight of root tuber was higher by 19∼157kg than that of control(610kg). In regression equation of fertilizer recommendation for two-year-old Saururus chinensis, the optimum level of N-P
2/O fertilizer was determined by 7.1, 2.5, 4.2kg/10a, respectively.
Mechanical harvest efficiency to rhizomes of Rehmannia glutinosa Libosch.
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 72~76
This study was carried out to determine an effective mechanical harvester for rhizomes of Rehmannia glutinosa Libosch. Labor-saving efficiency showed 69∼76% by using tillage operations with power tiller, digger attached to power tiller, and digger attached to tractor compared with manual harvest. Loss percentage of rhizomes by mechanical harvesters was 3.1∼ 9.3% higher, and fresh rhizome yield was 2∼6％ lower than that by manual harvest, respectively. Although it showed higher loss percentage of rhizomes and lower fresh rhizome yield compared with manual harvest, mechanical harvest using digger attached to power tiller or digger attached to tractor was effective in labor-saving for rhizomes of Rehmannia glutinosa Libosch.
Effects of Row Width and Plant Spacing Within Row on Yield in Scutellaria baicalensis George
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 77~80
This study was investigated to find out the optimum planting densities of Scutellaria baicalensis George about growth characters, yield components and yield at 3 planting densities by direct sowing cultivated after barley. Stem length was long in dense planting of 20
l0cm and short in spacious planting of 30
l0cm and 40
10cm by direct sowing cultivated after barley. Stem diameter was thick in spacious planting of 30
10cm and 40
10cm and was thin in dense planting of 20
10cm by direct sowing cultivated after barley. Length and dry weight of root per plant were decreased in dense planting of 20
10cm and were increased in spacious planting of 30
10cm and 40
10cm by direct sowing cultivated after barley. Yield of dry root was highest in optimum planting density(30
10cm：33 plants/㎡) by direct sowing cultivated after barley. The correlation coefficient between number of planting plant and stem length showed highly positive correlation. These characters of stem diameter, number of branches, main root length and yield of dry root mentioned above showed negative correlations with planting plants.
Unrecorded naturalized plants in Jeju(II)
Korean Journal of Plant Resources, volume 15, issue 1, 2002, Pages 81~88
Five naturalized species of taxa in Jeju such as Solanum ciliatum, Rubus fruticosus, Lepidium bonariens, Rudbeckia hirta, Solanum photeinocarpum have been found and given the Korea names. Among those species, four species such as Solanum ciliatum, Rubus fruticosus, Lepidium bonariense, Rudbeckia hirta, Solanum photeinocarpum. are naturalized in Korea but have not been reported yet and Rudbeckia hirta has been cultivated as a garden plant on the mainland Korea but it is found in the natural environment on Jeju island in Korea. And so we report here that Rudbeckia hirta is a naturalized species.
