Pyebaek of Jeonju area based on the method prepared by late old madame Park, Bokja can be characterized as follows: First, vegetables which could be obtained locally constituted the main body of materials of Jeonju Pyebaek and animal foods used in Pyebaek were dried fishe for the most of times. In the pre-refrigerator era, the main reason behind the heavy uses of dried fish such as dried abalone or octopus instead of animal foods can be attributed to the easy availability of dried fish. In recent years, foods made of animal foods has been indispensible items. Second for the patterns and decorations of Pyebaek natural figures such as birds, flowers, butterflies, loaves and half moon were imitated in making of octopus cuttings, squid cuttings, Yakkwa, Hwajeon, Dried persimmons, Jeonbokssam, etc. Beef jerky, Yeotgangjeong were decorated beautifully with pine nuts, shredded dried dates and raisins. Many colors were used in various items of Jeonju Pyebaek such as Hwajeon, Songpyun, Saji. Finally, flavors of Jeonju Pyebaek are sweet and tasty of sesame oil.
To examine aluminum toxicity on woody plants, Forsythia koreana cuttings were grown in the aluminum solution and ground water(pH 6.75). Aluminum solution were prepared 1.0, 2.5 and 5.0mM aluminum potassium sulfate, dilulted with ground water. Shoot growth, leaf number, leaf injury and leaf chlorophyll content were measured and compared among the treatments. In all growth-related characters(shoot growth. leaf number, leaf injury and leaf chlorophyll content), differences among the treatments were highly significant. Forsythia koreana cuttings were severely stressed in aluminum solution more than 1.0mM concentration.

These studies were carried out to investigate seed propagation method and conducted using stem cuttings of Styrax japonicus for using as a woody landscape plant. The results are obtained as follows. After the H\sub2\SO\sub 4\ and GA\sub 3\ treatment to the seeds of Styrax japonicus, three months of warm treatment followed by cold stratification for four months increased seed germination rate. The rooting rate of Styrax japonicus was increased by the treatment with concentrated IBA, especially highest at 7,000ppm. Rooting percentages were highest for cuttings taken on July 15, 1995. Therefore, the most effective method for rooting of Styrax japonicus was treatment with 7,000ppm IBA on July 15 cuttings, which showed rooting rate of over 90%. Half-leaf-remained cuttings were more effective than those with two leaves on rooting of Styrax japonicus. Dipping for 10 seconds in IBA solution resulted in rooting rate of over 70%. The longer the treatment time the worse the rooting.
This study was conducted to determine the effect of growth regulators, genotype, and cutting position on the rooting and root growth from cutting of Chrysanthemum zawadskii H.. Rooting rate of Keungugeolcho in the treatement of IBA 500 and 1000 ppm was the better than those of other treatments of IAA, NAA and Rooton. Rooting rate differed depending on the genotype. Hangryobonggugeolcho was better than Keungucheolcho in rooting rate. The treatment of rooton remarkably induced many roots from the cuttings of eight accessions of Chrysanthemum zawadskii H.. Also, rooting rate and number of root differed depending on cutting position. When cuttings including shoot tip were cultured on tray containing bed soil, rooting rate and number of root induced from cuttings with shoot tip was higher than when cuttings without shoot tip and with lateral axillary bud were cultured.

This study was carried out to compare the survival and mutation rates and mutation spectrum by gamma-irradiation on rooted and unrooted cuttings of three spray type ('Lovelydia', 'Yellowbabe', and 'Haetsal') and two standard type ('Vital' and 'Aqua') cultivars in roses. Two groups, rooted and unrooted cuttings were gamma-irradiated at 70Gy for 24 hours. The irradiated rooted and unrooted cuttings were planted in a greenhouse, and survival, mutation rates and mutation spectrum were investigated 30 weeks after planting, respectively. As a result, survival and mutation rates of gamma-ray irradiated plants were 16.4%~50.8% and 0~5.1% for unrooted cuttings, and 39.4%~55.1% and 0.7%~7.4% for rooted cuttings, respectively. In conclusion, both survival and mutation rates were a little higher on rooted cuttings than on unrooted cuttings. However, when only survived plants after gamma-ray irradiation were considered, mutation rates were 0~10% and 1.8%~14.1% for unrooted cuttings and rooted cuttings, respectively, showing no significant difference. In addition, diverse variations on color and number of petals or shape of flowers were detected both in plants from rooted and unrooted cuttings, which indicated that there was no significant difference in mutation spectrum between two groups.
To establish the mass propagation methods of Weigela subsessilis,, a promising native plant species for horticultural use, several factors influencing rooting from stem cuttings were evaluated. Softwood cuttings showed best rooting rate, 70~77%, in all the cutting media tested, 2.8 times more than hardwood cuttings in which perlite was best medium. The rooting from hardwood cuttings was promoted by higher concentration of all growth regulators used,500 mg.L$^{-1}$ NAA being the best with 80%. More than 80% of softwood cuttings treated by growth regulators produced roots, especially 100, 500, and 1000mg.L$^{-1}$ NAA producing 97%. Roofings from semi-wood cuttings was enhanced by all the growth regulators, except 1000 mg.L$^{-1}$ concentration in which rooting was reduce. Higher rooting rate was obtained by higher concentration and longer soaking duration of NAA in case of hardwood cutting. Softwood cutting showed 100 % rooting by soaking treatment with 500 mg.L$^{-1}$ NAA for 3 min. Rooting rate of semi-hardwood cuttings was promoted by higher concentration and longer soaking with growth regulators, However, the degree of improvement was lower than soft and hardwood cutting.
This study was conducted to determine the effects of mycorrhizal inoculation and ortet ages on the rooting of Quercus acutissima cuttings. The cuttings taken from 12-week-, 2-year-, 4-year-, and 20-year-old plants were rooted in mid summer in the rooting medium (vermiculite 2 : peatmoss 1 by volume) with or without Pisolithus tinctorius (Pt) and Glomus sp. inocula and IBA under intermittent misting system in an open shed. The average percentages of rooting were about 82%, 49%, 29%, and 13% for cuttings taken from 12-week-, 2-year-. 4-year-, and 20-year-old seedlings, respectively. Pt inoculation, enhanced rooting of cuttings at all age classes, except 12-week-old seedlings, with the highest enhancement(22%) observed in cuttings taken from 20-year-old trees. The highest percentage of rooting in each age group eras 88.9% in 12-week-old seedlings treated with Pt plus 3.000ppm IBA, 75% in 2-Year-old plants with 1,000ppm IBA, 58.3% in 4-year-old plants with 3.000ppm IBA and 22% in 20-year-old plants. The addition of Glomus sp. fungus inoculum failed to enhance rooting. Pt mycorrhizal inoculation enhanced root dry weight, length, and diamter of adventitious roots at cuttings taken from 12-week- and 20-year-old trees, except the cuttings taken from 4-year-old seedlings. Rooted cuttings had more total nitrogen content in the leaves than unrooted cuttings, and the greater rooting response was associated with the higher phosphorus content in the leaves.

This study was conducted to investigate optimal conditions for cutting propagation of the strawberry cultivar "Sulhyang" through the collection methods of cuttings (runners tips), leaf number of cuttings, and cutting time. Cuttings were collected from the mother plant in the nursery bed (MP) and plants after fruit harvest (HP); the leaf number of cuttings was 0, 1, and 2, and the cutting time was at one-week intervals from June 4 to July 9. The survival rates for MP and HP cuttings were notably high, reaching 99.5% and 98.7%, respectively, but no significant difference was found. The number of roots were higher in MP cuttings, and there was no significant difference in crown and leaf growth. The fruit yields were 419.2 and 428.4 g, for MP and HP cuttings, respectively. The survival rates according to leaf number of cuttings were 98.1% and 98.3% for 1 and 2 remaining leaves, respectively, and remarkably lower at 25.3% for no remaining leaves. The root numbers were 26.0 and 26.3 for 1 and 2 remaining leaves, respectively, compared with 23.5 for no remaining leaves, with no significant differences in crown and leaf growth. The fruit yields were 424.4 and 421.5 g for 1 and 2 remaining leaves, respectively, and 396.7 g for no remaining leaves. The survival rates according to cutting time was over 97.2% in all cutting time without any difference in each treatment. The root, shoot, and crown of the nursery plant before planting showed the best growth in the cuttings on June 4 and 11, resulting in the highest fruit yields of 433.3 and 426.4 g, respectively, with the lowest yields at 384.5 g for cutting time on July 9. Both MP and HP materials proved suitable for strawberry cuttings. The optimal leaf number for cuttings was at least 1, and the optimal cutting time in Gyeongnam area was evaluated as around June 4-11.
Rootability of the hardwood cuttings of mulberry was related not only histological characteristics but dependent on biochemical properties. In this connection, the characteristics of the hardwood cuttings were histologically observed and the growth substances produced by the cuttings were also identified by means of mung bean bioassay. Amino acid, carbohydrate, nucleic acid contents, and the C/N ratio were also analysed. The results are summarized as follows. 1. There were differences in rootability of cuttings between mulberry species and varieties Among the three mulberry species tested, Morus Lhou Koidz. showed the highest rootability while M. bombycis showed the lowest one. In varietal differences in rootability, it was shown that the varieties could be grouped according to rootability: high varieties(above 80%), medium(41~79%), and low(below 40%). The higher varieties were Kemmochi, Nakamaki, Kosen, and Wusuba roso. 2. The histological characteristic of the hardwood cuttings most closely related to rootability was cell layer arrangement in the sclerenchyma tissue. The lower rootability varieties developed two or three overlapping cell layers in the bark tissue and in the higher rootability varieties they were scattered over the primary cortex. 3. In the higher rootability varieties, there was a positive correlation between the development of root primodia and rootability of the hardwood cuttings. It was also shown that there was a close relationship between the size of primodia and the surface area of the lenticel with rootability of the cuttings. 4. Effect of growth substances extracted from the hardwood cuttings were determined by mung bean bioassay. The higher rootability varieties usually showed higher activities of the growth substances, in contrast the lower rootability varieties showed higher activities of the inhibitory substances. 5. It was evident that the substance separated by paper chromatography was identified as indole acetic acid with $R_f$ value ranging from 0.3 to 0.5. The other substances detected at a $R_f$ value ranging from 0.8 to 1.0 and origin to 0.1 were also responsible for rooting. 6. There exists a quantitatively different distribution of growth substances in a synergistic system in the tissues of cuttings, and the balance between growth and inhibitory substances gives rise to the development of rooting. Particularly, no descent of the substances from winter buds resulted in no rooting of cuttings but these substances were produced a week after planting in a warm environment. 7. It was shown that there were positive correlations between carbohydrate ($r=0.72^*$) and total sugar ($r=0.67^*$) and rootability, respectively, but there were negative correlations between reducing sugars ($r=-0.75^*$) and rootability. 8. High C/N ratio gave rise to high rootability($r=0.67^*$). The latter therefore depended on high amount of carbohydrate rather than nitrogen in the cuttings. 9. The content of RNA and DNA in the cuttings was not changed for upto two weeks after the cuttings were planted. Then an increase in RNA content took place in only the high rootability varieties. 10. There were quantitative and qualitative differences in the compositions of the amino acids between the high rootability varieties and the low rootability varieties. More aspartic acid and cystine were found in the higher rootability varieties than in the low rootability varieties.
This study was conducted to find out the propagation method of a rare variety Daphne kiusiana Miq. in Korea through softwood cuttings. Daphne kiusiana Miq are the evergreen broad leaf tree which have lived in the southern part of Korea. The flowering time of Daphne kiusiana Miq is early spring and the flower has an attractive fragrance. Generally, plants are dioecious and only the male plants are found in Korea. Propagation by seed is very difficult in this tree. Softwood cuttings were taken to establish an efficient propagation method in Daphne kiusiana Miq Cuttings were grown in perlite:vermiculite (1 : 1), perlite, vermiculite, sand rooting media under shaded greenhouses during summer in 2007. The rooting rates of cuttings were 86.7%, 95%, 75% and 95% in perlite:vermiculite (1 : 1), perlite, vermiculite and sand media, respectively. Softwood cuttings taken on July and rooting at $27^{\circ}C$ were significantly improved the growth and rooting rates. Softwood cutting can be an effective means of propagation in Daphne kiusiana Miq.
