  • Chestnut trees have been used as a dyeing material, which are grow naturally, are cultivated all the area of Korea. So, there is abundant amount of the materials and they have better colorfastness than other natural dyeing materials. But chestnut husk extract is good at silk and wool fabrics, not cotton fabrics. That's why many methods using chestnut extraction for dyeing are being studied. But most of them depend on treatment method with chemical material which doesn't fit with the aim, using natural materials. Therefore in this research, we used protein pre-treatment method which is dyeing chestnut husk extract after treating at cotton fabrics with bean sap. And we studied the effect of dyeability of chestnut husk extract to cotton fabrics. As a result of pre-treatment of bean sap at cotton fabrics, dyeability was increased. Besides laundering fastness, dry cleaning fastness, perspiration fastness and light fastness were almost increased.

  • Samples showing yellow mosaic symptom of Lilium spp. with necrotic fleck, stunting, malformation, and colour breaking were collected from lily-growing areas in the southern part of Korea. Two viruses were distinguished under a electron microscope and their host range, serological reaction, stability in sap, type of aphid transmission, and relations with cells and tissues were examined. Broad bean wilt virus (BBWV) was transmitted by sap-inoculation to 23 plant species in 8 families and by the aphid, Myzus persicae. This virus was inactivated after 10 min at 70C, at dilution of $10^{-3}$, and after 6 days at about 20C. Electron microscopic examination of purified preparation showed that the virus is spherical particle of 28nm in diameter. The virus reacted positively with BBWV-antiserum in agar gel diffusion test. In ultrathin sections of BBWV infected tissues, large aggregates or crystalline array of virus particles and vesicular body were found in the cytoplasm, vacuole, and nucleus of mesophyll cells. Cucumber mosaic virus (CMV) was transmitted by sap-inoculation. Electron microscopic examination of its purified preparation showed spherical particles of 30nm in diameter. The virus reacted positively with CMV-Y strain-antiserum in agar gel diffusion test. In ultrathin sections of CMV infected tissues, crystalline array of virus particles were found in the vacuole and a large number 0f virus particles were found in the cytoplasm and the plasmodesmata of mesophyll cells. When each of these viruses was retransmitted to Lilium tigrinum. L. concolor, and L. auratum, BBWV induced slight symtoms and colour breaking, but CMV induced yellowing mosaic or necrotic fleck.

  • Gladioli (Gladiolus hybridus) showing flower colour breaking, leaf mosaics, necrotic fleck, and dwarfing or lack of visible symptoms were collected from gladioli growing areas in Taegu and Kyungpook province, Korea. The two viruses isolated from the naturally infected gladioli were identified as ban yellow mosaic virus (BYMV) and clover yellow vein virus (CIYVV) by their host range, immunosorbent electron microscopy (ISEM), enzyme-linked immunosorbent assay (ELISA), direct tissue blotting immunoassay (DTBIA) and intracellural symptoms. In ultrathin sections of BYMV and CIYVV infected tissues, laminated aggregate-type inclusions, cytopalsmic bodies and nuclear inclusions as well as filamentous virus particles were observed in the cytoplasm of parenchyma cells. By DTBIA and ISEM, BYMV was detected in all tested gladiolus plants showing severe or mild mosaic symptoms, whereas CIYVV were mainly detected from those of mild mosaic symptoms. BYMV is the most prevalent in commercial gladioli and present major production problems. Detection sensitivity of BYMV and CIYVV in crude sap of infected gladiolus leaves by ISEM was about twice compared with ELISA. In a comparison of ELISA, ISEM, DTBIA, BYMV was detected in same degree by DTBIA in samples where sap extracts were positive in both ELISA and ISEM. DTBIA provides a specific, rapid, and simple tool for large-scale diagnosis of BYMV.

  • Samples showing mosaic symptom of cowpea (Vigna sesquipedalis) with vein banding, chlorotic spot, vein yellow were collected from Chinju areas in Korea, Two viruses were distinguishable by stability in sap, host range, and relations with cells and tissues were examined under an electron microscope, Blackeye cowpea mosaic(BICMV) was sap-transmissible to 7 plant species in 2 families, Of the plants, only leguminous species were systemically infected. This virus was inactivated by heating at $50-65^{\circ}C$ for 10 min, by diluting at $10^{-4}-10^{-5}$, and aging at room temperature for 1-6 days. Preparations examined under the electron microscope by direct negative staining method(DN -method) always showed particles of flexuous filament bout 750nm in length and cytopasmic inclusions. Cytoplasmic inclusions and virus particles were also confirmed to present in the cytoplasm of a mesophyll cell by ultrathin sections of BICMV infected cowpea leaves. Cucumber mosaic virus (CMV) was transmitted by sap- inoculation on inoculated leaves of Chenopodium amaranticolor, C. quinoa producing local lesions, but non-inoculated upper leaves of Nicotiana glutinosa, Cucurbita pepo and Vigna sesquipedalis producting systemic mosaic symptoms. Electron microscopic examination of virus preparation by direct negative staining showed spherical particles of about 30nm in diameter. In ultrathin sections of CMV infected tissues, virus particles of crystalline array were found in the vacuole and a large number of virus particles were found in the cytoplasm and the plasmodesmata of mesophyll cells.

  • Isolates of soybean mosaic virus (SMV) strains classified based on virulence in silt resistant soybean cultivars caused the same reactions in soybean cultivars used as differentials as those obtained by sap inoculations to the same cultivars. Five species of aphids (Myzus persicae SULZ., Aphis craccivora KOCH, Aphis citricola VAN., Rhopalosiphum maidis FIT., End R. padi L.) were able to transmit each of SMV strains. However, R. maidis and R. padi were inefficient vectors for transmission of SMV strain G3. Spread if four SMV strains (G2, G3, G6, and G7) was monitored in the field from sapinoculated plants in a one meter row of Williams soybeans (source plants) to plants in an adjacent row of Williams 80cm away (test plants). Test plants wert downwind from the source plants. A complete block design was used. Spread of strain G6 was significantly greater than that of other three strains. Two hundred six aphids were collected from June 27, 1979 to August 2, 1979 in the same field. A. citricola was the mist prevalent, comprising $68\%$ of the total aphids. Yields of Williams inoculated with each strain were also compared. Yields were the least from plants inoculated with strain G2 following G6, G3, and G7 in that order.

  • In June 2019, Angelica acutiloba plants showing virus-like symptoms such as chlorotic local lesion and mosaic on the leaves were found in a greenhouse in Nonsan, South Korea. To identify the causal virus, we collected 6 symptomatic A. acutiloba leaf samples and performed reverse transcription polymerase chain reaction (RT-PCR) analysis using specific detection primers for three reported viruses including tomato spotted wilt virus (TSWV). RT-PCR results showed that five symptomatic samples were positive for TSWV. Mechanical sap inoculation of one of the collected TSWV isolate (TSWV-NS-AG28) induced yellowing, chlorosis and mosaic symptoms in A. acutiloba and necrotic local lesions and mosaic in Solanaceae species. Phylogenetic analysis based on the complete genome sequences showed that TSWV-NS-AG28 had a maximum nucleotide identity with TSWVNS-BB20 isolated from butterbur in Nonsan, South Korea. To our knowledge, this is the first report of TSWV infection in A. acutiloba.

  • 1. For the types of boiled rice, there were 1 type of bap, 1 type of jebap cooked with glutinous rice, 13 types of boiled rice cooked by mixing grains and nuts such as daemakban, somakban, jobap, cheongryangmiban, jobap, gijangbap, yulmubap, hyeonmibap, boribap and patmulbap as well as patbap, congbap, byeolbap and bambap etc as ogokbap. Also, there were 12 types of bap cooked by mixing herb medicinal ingredients such as cheongjeong, oban, boksungabap, gumeunsaekbap, hwanggukgamchobap, yeongeunbap, okjeongbap, gogumabap, dububap, samssibap, dorajibap, gamjabap, songibap and jukshilbap. There were 7 types bap cooked as unique one bowl dish at the present as bapby mixing fish, meat, shellfish and milk as ingredients are hwangtang, gyejanggukbap, janggukbap, gulbap, kimchibap, chusaban and bibimbap, etc and the types of bap that have been analyzed are 34 total. 2. For the food ingredients used in bap types 23 types of miscellaneous grains, 5 types of nuts and 11 types of meat, 6 types of fish, 35 types of vegetables, 2 types of fruit including pears or peaches were used. Garlic wasn't used perhaps because of it being boiled rice 3. Types of Sap by Cooking Methods. (1) The ssalbap was cooked by first boiling water, putting in rice grains and boiling hard to be cooked as overcooked bap (rice). (2) The japgokbap (boiled cereals) has used buckwheat, barley job's tear, etc to be boiled down by soaking the ones with large grains (beans) first in advance to be boiled down or cooked by crushing into fine pieces. The red bean, etc was boiled down in advance or placed at the bottom of pot by cutting into two pieces while jujube or nut was cut into three pieces to cook the bap by pouring a lot of water and mixing other ingredients. (3) The gukbap (soup boiled rice), etc were cooked by squeezing out the yellow chrysanthemum that has dried chrysanthemum to cook the boiled rice by putting in rice and gukbap, meat or bones, etc were boiled down for a long time and decorated with meat or wild greens by mixing the bap in the meat juice. For gulbap (oyster boiled rice), etc, it was cooked as ingredients were stir fried in advance or washed and put in when the bap was about half cooked. (4) For bibimbap (mixed boiled rice), after the bap was overcooked first with rice, the wild greens were mixed lightly with bap beforehand, then the wild greens, decorations and garnishings were laid above rice and red pepper powder was sprinkled. (5) Namchok leaves, etc were boiled to cook the boiled rice with rice after being cooled while namchok stem and leaves were pounded to make juice and cooked the bap with rice. The peach, lotus root and yams were cut into fine pieces to be put in together when rice was about half done. The bellflower was soaked in water to be boiled down for a long time while potatoes and pine mushrooms, etc were cut into fine pieces to cook the bap (boiled rice) with rice.
