Effects of neutron beam irradiation on seed germination, growth and RAPD pattern of tobacco (Nicotiana tabacum L. cv.; N. plumbaginifolia) and rice (Orya sativa L. cv.) plants were estimated. Seed germination rate was not significantly changed by the neutron beam treatment in both tobacco and rice seeds. And there was no significant differance in growth of the plants by the neutron beam treatment. Interestingly, however, some of morphological changes, including leaf shape (about
), stem color and leaf color were observed in neutron beam treated tobacco plants. In addition, abnormal flower in petal was observed in the neutron beam treated plant. This results indicate that neutron beam is able to use as an effective mutagen in plant mutations. Scorable products from 20 primers were obtained by RAPD analysis in the leaves of the beam irradiated tobacco plants and most of the plants showed the similar band patterns.

This study was conducted to establish the system of effective in vitro propagation by various explant sources culture of Bippeastrum hybridum Hort, 'Dazzler'. We tested the effects of optimal explant source, plant growth regulators on bulblet formation and plant regeneration. Callus was readily produced on the different tissues excised from floral buds whereas, bulbs and shoots were formed only on pedicel explants as compared with anthers, styles and ovaries. Pedicel is the best optimal explant for in vitro propagation. Two distinct pathways, organogenesis through callus and direct bulblet formation, could be recognized in pedicel culture. Up to the
of bulblet formation and shoot organogenesis from the pedicel in fifteen days before anthesis were effectively induced by MS medium supplemented with 0.5 mg/L NAA and 1.0 mg/L BA. Plantlet regeneration was successfully achieved from pedicel-derived callus, via shoot bud induction or direct bulblet formation. The bulblets with blooming flower were produced within 2 years.

In order to investigate effects of dyeing conditions on the dyeing characteristics in silk during natural dyeing using indigo plants , various dyeing conditions including the temperature of dyeing solution, dyeing period, the concentration and pH of dyeing solution and mordants were treated. As the temperature of dyeing solution decreases low, the color of silk surface showed lower b value. The color of silk surface showed G line when the dyeing solution was
and room temperature and GY line at more than
. Coloring degree increased high as the temperature increases. Dyeing period showed no effect on the surface color, but as dyeing period was longer the coloring degree increased. When the concentration of dyeing solution was
, the silk was colored to BG line and
to B line. The coloring degree increased as the concentration of dyeing solution more increased. The pH of dyeing solution sensitively affected coloring of silk. The pH lower than 7 showed G line, pH 8 showed GY line and pH 9 showed YR line. Coloring degree decreased as pH was more increases. Surface color of silk was different according to the kinds of natural mordants and coloring degree was increased by the natural mordants.

Newly introduced two lines of apios (Apios americana Medikus, red-vine and green-vine) were grown in Jeju island, to clarify their growth and production characteristics as well as to develope as a new edible crops in Korea. Both lines bloomed but did not develop to pod and seed. The red-viny line showed the habit of more early growth and maturity compared with green-viny line. Fresh tuber yields per 10a harvested in late November ranged from about 500kg to 800kg as according to the lines and cultural condition. Fresh tuber yield of red-viny line was relatively greater than that of green-viny line, mainly due to their higher tuber number per plant. Among the planting dates(April 1, April 16 and May 1) of seed tubes, highest tuber yield was obtained on May 16 planting. And the stacking cultivation culture was better than non-stacking cultivation in respect of tuber yield and disease avoidance. These results indicate that apios can produce in Jeju island, and in order to extend its cultivation to farmers it will be needed to develope some cultivars with high yields as well as labor-saving cultivation methods.

Korean Journal of Plant Resources, volume 18, issue 3, 2005, Pages 433~440
Four varieties of perilla(Perilla ocimoids L.) were tested to investigate the ecological adaptation of the crop to variations in sowing time extending from April 25 to July 25 with an interval of 30 days between each of the four sowing. As sowing time was delayed, the plant height, the number of first branches and cluster, the weight of fresh and dried stems, the day to germination and flowering decreased, showing a highly negative correlation between the showing dates and these characteristics, but a highly positive correlation between days to flowering and the required accumulated temperature. With early sowing under low temperature and long day conditions, it took about 132 days from sowing to flowering due to the long period of vegetative growth, but as sowing was delayed, the days to flowering decreased with a minimum period of 57 days. The yield of seeds in each case varied with each variety. Type A(Nonsan var.) and type B(Jinchon var.) had higher yields when sowed earlier. But type C(Namyang var. and Wooljin var.) had its highest yield in the plot sowed on May 25 and the 1000 grain weight showed a tendency to increase as sowing was delayed. In conclusion, the perilla was preyed to be a short-day plant that flowers from the begining to the middle of Sep. regardless of sowing time, so that the sowing time should be decided after due consideration of the length of the vegetative growth periods of the varieties.

Photo system II (PSII) is one of the two photosynthetic reaction centers in the chloroplast of higher plants. The chlorophyll a/b-light harvesting complex serves primarily as an antenna for PSII. We isolated a cDNA that encodes a chlorophyll a/b-binding protein (Cab) from Panax ginseng. The small subunit consists of 935 nucleotides long and has an open reading frame of 795 bp with the deduced amino acid of 265 residues (pI 5.63), 28.6 kDa. The deduced amino acid sequence matched to the previously reported Cab genes. Their degree of amino acid identity ranged from 68 to
. Phylogenetic analysis based on the amino acid residues was showed that the ginseng Cab gene was grouped with P. persica (AAC34983), A. thaliana (AAD28771), G. hirsutum (CAA38025), G. max (AAL29886), and V. radiate (AAF89205).

This study was carried out to induce plant regeneration via shoot formation from sucker explants of Rubus fruticosus L. To induce adventitious shoots, sucker explants were sterilized in
NaOCl solution, and cultured on the MS solid medium supplemented with kinetin (0.5, 1.0, 3.0 mg/L) and BA (0.5, 1.0, 3.0 mg/L), respectively. As above, to induce adventitious shoots, sucker explants were cultured on the MS solid medium supplemented with IBA (0, 0.1, 1.0 mg/L) and BA (0, 0.1, 1.0, 2.0 mg/L). After 4 weeks of culture, the highest frquency
of shoot formation from sucker explants was obtained from the medium with 1.0 mg/L BA. The highest shoot number per explant from in vitro shoot explants was 5.3. After 10 weeks of culture, the number of shoot per explant was increased. The highest frequency
of root formation was obtained at 0.5 mg/L glycine medium, when the explant with shoot were cultured on the MS medium containing glycine at various concentrations from 0 to 2.0 mg/L. The survival rate of the plantlets after transfer to plastic pots containing sand, soil, and vermiculite (1:1:1, vol.) was
. The results indicate that micropropagation procedure can be applied for an efficient mass propagation of Rubus fruticosus.

Effects of proton beam irradiation on seed germination and growth pattern of tobacco (Nicotiana tabacum L. cv. BY-4; N. plumbaginifolia) and rice (Oryasativa L.) plants were estimated to develop the efficient conditions of irradiation. Seed germination rate was decreased by increasing the proton beam the current and the beam irradiation time in both tobacco and rice seeds. The beam irradiation conditions showing
germination were over 60 sec at 10 nA, approximately 5 sec at 100 nA and at 500 nA beam current in tobacco seeds. And the conditions of
germination were 60 sec at 10 nA, and 100 nA and 30 sec at 500nA in rice (cv. Dongjin 1) seeds. The growth of irradiated plants was decreased, but significant difference in morphological changes was not observed by the proton beam treatment. The proton beam is able to use as a mutagen, but some of the factors including beam size and beam detector-system must be established for efficient usage of the beam.

Korean Journal of Plant Resources, volume 18, issue 3, 2005, Pages 470~478
The objective of present study was to investigate the hepatoprotective and antioxidative effects of onion extracts. Primary cultures of rat hepatocytes were incubated with 1.5 mM tort-butyl hydroperoxide(t-BHP), potent oxidizing agent to liver, for 1 hr in the presence or absence of various concentrations (0, 0.01, 0.05, 0.1 or 0.3 mg/ml) of onion extract. Incubation with t-BHP increased glutamic oxaloacetic transaminase(GOT) and lactate dehydrogenase(LDH) acitivities and thiobarbituric acid reactive substances(TBARS) concentration but decreased 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide(MTT) reduction. Onion extracts at the concentration of 0.05 mg/ml decreased t-BHP-induced GOT and LDH activities. Onion extract at the concentration of 0.1 mg/ml increased t-BHP-induced MTT reduction. Onion extract at the concentration of 0.01 mg/ml decreased t-BHP-induced TBARS concentration. Taken together, onion extracts prevented t-BHP-induced hepatocyte injury and lipid peroxidation. Catalase, glutathione peroxidase(GSH-Px) and glutathione reductase(GSH-Rd) activities of hepatocytes were significantly decreased by t-BHP. Onion extracts at the concentration of 0.1 mg/ml prevented t-BHP-induced decrease in catalase, GSH-Px and GSH-Rd activities. Onion extracts prevented hydroxyl radical-induced single-strand breakage in dose-dependent manner when plasmid DNA was incubated with various concentrations of onion extracts in the presence of Fenton reagents producing hydroxyl radical. These results demonstrate that onion extracts suppressed t-BHP-induced cytoctoxicity, decreased viability and lipid peroxidation and increased GSH-Px, GSH-Rd and catalase activities. Thus hepatoprotective and antioxidant effects of onion extract seem to be due to, at least in part, the increase in antioxidant enzyme activities as well as prevention from hydroxyl radical-induced oxidation, followed by inhibition of lipid peroxidation.

This study was conducted to clarify the effects of chemicals and physical treatment on the split of flower stalk and the vase life of Lycoris squamigera and Lycoris radiata. There was no split of flower stalk for the Lycoris squamigera and the Lycoris radiata after the harvest of flowers and the immersion in 4 mM STA solution for 30 minutes. It was effective for the vase life of Lycoris squamigera that cut flower was pre-treated in 4 mM STS solution for 30 minutes and immersed in
sucrose + 150 ppm 8-HQS +4 ppm Rox preservative solution. The optimum periods of hot water treatments for the prevention of flower stalk split and the elongation of vase life for the cut flowers were 15 to 25 seconds for the Lycoris squamigera and 5 to 10 seconds for Lycoris radiata. Burning the cut parts of flower stalk for 10 to 30 seconds was effective for the prevention of flower stalk split and the elongation of vase life for the Lycoris squamigera, and 10 to 15 seconds for the Lycoris radiata. The vase lifes of Lycoris squamigera and Lycoris radiata were elongated when flower stalk was cut by an incline of 45 degrees compared with the horizontal cut. And Banding the flower stalks of cut flowers was effective for the prevention of flower stalk split and the elongation of vase life for the Lycoris squamigera and the Lycoris radiata.
