To investigate weathering and surface characteristics of coating film on lumbers coated with Hwangchil(varnish of Dendropanax morbifera), we carried out to investigate the resistance against discoloration, value of crack and surface characteristics of coating films on seven domestic lumbers and those of four introduced tropical lumbers. There was investigated to evaluate the properties of coating films by the varnish of Dendropanax morbifera. There was insignificant correlations between the hardness and moisture contents of each lumber treated by the varnish. There was no significant correlations between the thickness of coating film and the hardness, either. Although we investigated 11 wood species, we found only three species as resistance wood species against discoloration; Diospysos spp., Abies holophylla and Ulmus davidiana. The crack of coaing films was the largest on Zelkova serrata followed by Juglans sinensis, Cercidiphum japonicum, Tectona grands, Ulmus davidiana, Guibourtia tessmannii, Diospysos spp. and Dalbergia latifolia. However, there was no crack of coating films on the lumbers of Juniperus rigida, Prunus serrulata var. spontanea and Abies holophylla. The crack of coating film showed positive correlations with the thickness of coating film and hardness. The surface characteristics of the coating films evaluated on the basis of $R_{a}$ values indicated the lumbers of Ulmus davidiana($0.14{\;}{\mu}m$), Juniperus rigida($0.1 5{\;}{\mu}m$), Guibourtia tessmannii($0.19{\;}{\mu}m$), Dalvergia latifolia($0.20{\;}{\mu}m$) and Diospysos spp.($0.20{\;}{\mu}m$), Cercidiphum japonicum($0.24{\;}{\mu}m$) as good species while there was insignificant differences between softwoods and hardwoods. Tectona grands, Prunus serrulata var. spontanea and Abies holophylla showed rough surface with $1.53~2.63{\;}{\mu}m$ of $R_a$ values. The four kinds of rough indices($R_a,{\;}R_z,{\;}R_{max}{\;}and{\;}R_q$) showed very low correlations with moisture contents with the correlation coefficients. The $R_a{\;}and{\;}R_{max}$ also showed slight relationship with hardness.

The purposes of this study was to investigate accuracy and indigenity of landscape plant species in planting design and construction at housing complex and offer basic data for improving precision of planting construction. The scientific name of landscape plant species was described in planting drawings at only two sites among twelve survey sites. According to analysis on indigenity of plant species in planting drawings, it was found that the component ratio of foreign species was the highest and the component ratio of native species at public housing complex was the lowest. The component ratio of landscape plant species in planting construction was severely differed to that of planting drawings. Also the component ratio of cultivar was higher than that of planting drawings due to planting of sevveral cultivars for one species in planting drawings. In the result of accuracy analysis on landscape plant species in planting construction, it was found that mean ratio of inacccurate species was 33.2% at public housing complex, 29.6% at local company housing complex and 26.4% at nationwide company housing complex. It was found that several cultivars were planted for one species in planting drawings. The representative species which were planted by several cultivars were Camellia japonica, Rododendron spp., Prunus spp. and Magnolia spp. and so on. In order to promote the precision and speciality of planting design and construction, scientific and cultivar name of plants should be described in planting drawings.

Very little utilization of the fruits of Malus baccata(Rosaceae) has been employed for food and medicinal plants except for preparing fruit beverages. But, it was estimated as valuable to investigate the chemical components for the botanical resource of this plant. In this study, it was found that the fruits of this plant contained primary long chain alcohol, ${\beta}-sitosterol$, campesterol, ursolic acid and ${\beta}-_D-glucosides$ of ${\beta}-sitosterol$ and campesterol. However, phloretin(dihydrochalcone) and its 5-O-glucoside(phloridzin) known as plant growth regulators in many Rosaceae plants were not found in this plant material by co-TLC analysis with authentic specimens. Although plant sex hormone, estrone, was often contained in relates of M. baccata, e.g., Prunus spp., Crataegus spp. and Malus spp., this compound was not detected in this fruit by comparison with an authentic material. By RIC chromatography, it was suggested that the Soxhlet extraction by the solvent of ether was excellently useful to extract ursolic acid efficiently.

This study was conducted to analyze the current state and symbolic meanings of floral emblem designation in local governments of South Korea. The scope of local governments subject to analysis was limited to special city, metropolitan city, province, self-governing province, city, self-governing city, county and district based on their administrative divisions. The floral emblems of local governments and their symbolic meanings as of 2019 were examined. A total of 44 plant species were designated as floral emblems. Many plant species with high designation frequency were included in Rhododendron spp., Rosa spp., Camellia spp., Magnolia spp., and Prunus spp.. Plant species with higher designation frequency tended to have more symbolic meanings. A total of 155 terms were used for the symbolic meanings assigned to all the designated floral emblems. The major symbolic meanings were relevant to material affluence or economic growth, community spirit, and personality generally required from local residents. Most of the plant species linked to the top 10 most frequently assigned terms in symbolic meaning were those of the top 10 most frequently designated floral emblems. In the case of floral emblems with high designation frequency, it was shown that they were linked with various symbolic meanings in order to grant identity with regional distinctiveness and differentiation, regardless of the symbolic meaning that the designated flowers generally have. However, the floral emblems with low designation frequency seem to have relatively strong physical or emotional relevance with local governments and thus are expected to have high utilization in regional branding and tourism marketing.

A lot of SSRs (simple sequence repeats) in peach and pear from enriched genomic libraries and in peach from a cDNA library were developed. These SSRs were applied to other related species, giving phenograms of 52 Prunus and 60 pear accessions. Apple SSRs could also be successfully used in Pyrus spp. Thirteen morphological traits were characterized on the basis of the linkage map obtained from an $F_2$ population of peach. This map was compiled with those morphological markers and 83 DNA markers, including SSR markers used as anchor loci, to compare different peach maps. Molecular markers tightly linked to new root-knot nematode resistance genes were also found. A linkage map including disease-related genes, pear scab resistance and black spot susceptibility, in the Japanese pear Kinchaku were constructed using 118 RAPD markers. Another linkage map, of the European pear Bartlett, was also constructed with 226 markers, including 49 SSRs from pear, apple, peach and chewy. Maps of other Japanese pear cultivars, i.e., Kousui and Housui, were also constructed. These maps were the first results of pear species.
