Tripitaka Koreana was made during Koryo Dynasty from 1236 to 1251 A.D. Buddhist scriptures were engraved on 81.340 wooden plates. This study was made to identify species in these archaeological wooden plates using light and scanning electron microscopes. The results were as follows more than 62% of whole specimens investigated was Prunus sp., which was used in wooden plate 64% and wooden plate edge 56%, Pyrus sp. was used 13% of whole specimens and 31% of wooden plates. Therefore, 75% of whole Tripitaka Koreana was made by these two species. Acer sp., Betula sp., Machilus sp., Cornus sp., Daphnilhyllum sp., Prunus sp. were also identified but extreamly rare. Especially Machilus sp. and Daphnilhyllum sp. originally distributed in subtropical zone of west and south coast in Korea were identified, suggested strongly another engraving place of Tripitaka Koreana, Namhae bunsadogam.

A paleobotanical study of the fossil woods has been carried out from the Tertiary Janggi Group, Pohang Basin. Three species belonging to three genera of Ulmus sp., Prunus sp., and Acer sp. were identified from the Lower Coalbearing Formation, and two species of two genera of Taxodioxylon sp. and Fagus hondoensis (Watari) from the Upper Coal-bearing Formation. As our specimens are mostly poorly preserved, it is difficult to give clear specific names, but mostly are all characteristic constitutional elements of the Miocene fossil woods in Korea. The values of mean sensitivity measured from the fossil woods of Lower and Upper Coal-bearing Formations are 0.367 and 0.370 respectively, but they are more than 0.30. Based on the present two data mentioned above, it stands to reason that there were many changes in the water supply to the roots of the woods or having influence to some degree each year because of the seasonal changes in rainfall.

Plant-parasitic nematodes were surveyed at peach orchards in Gyeongbuk province for three years from 2000 to 2002. Species, density, frequency, Simpson's index, Shannon and Wiener index, and prominence value were analyzed. Plant-parasitic nematodes were isolated from 97 orchards out of 124 orchards. More important plant-parasitic nematode genera on peach were Tylenchorhynchus nudus, Criconemoides informis, Paratylenchus elachistus, Pratylenchus vulnus, and Helicotylenchus digonichus. Aphelenchus sp., Tylenchus sp., Heterodera sp., Scutellonema sp. were found, but were not important. Root-knot nematodes were not found even though they were serious in foreign countried.

Twenty-five species of pests had occurred at orchards of Japanese Apricot, Prunus mume Siebold & Zucc., in Hadong and Jinju (Gyeongsangnam-do province) from 2005 to 2007. Rhopalosiphum rufiabdominale (Sasaki), Singapora shinshana M., Tetranychus viennensis Zacher, and Synanthedon hector B. occurred as major pests and Anthonomus persicae sp. nov., Grapholita molesta (Busk), Spodoptera litura F., and Myzus persicae (Sulzer) as a sporadic pests. The population of S. shinshana had increased continuously during the season, from late April to late October. The population of T. viennensis occurred early May, reached the highest peak in late June to early July, and then declined with worsening consequences of nutritional conditions in the apricot leaves. A. persicae was observed to occur before breaking flower-bud of apricot and emerged adults were found in April to early May.

The purpose of this study was to investigate the effect of maesil(Prunus mume) on Dongchimi fermentation. Dongchimi with 0, 2, 4 and 6%(w/v) maesil was fermented at 10℃ for 45 days. The pH of Dongchimi decreased slowly in all samples during fermentation. Total acidity of Dongchimi increased gradually during fermentation and total acidity of Dongchimi with maesil was higher than that of control. Redox potentials decreased until 30 days of fermentation but increased thereafter. Reducing sugar content increased in the initial stage of the fermentation periods, and then it decreased gradually, the reducing sugar content of Dongchimi with maesil was higher than that of control. The content of total vitamin C was much higher in Dongchimi with maesil. In color measurement, lightness value decreased gradually, redness and yellowness values increased gradually during fermentation but decreased thereafter. The content of hot water soluble pectin(HWSP) decreased as the fermentation proceeded but the content of hydrochloric acid soluble pectin(HCISP) and sodium hexametaphosphate soluble pectin(NaSP) increased.

This study was carried out to analyze community character and classify forest community with phytosociological method and quadrat method to forest of Mt. Busosan in Buyeo-Gun.1. Communities by phytosociological method were classified into Pinus densiflora community and Quercus sp. community. With the classification of TWINSPAN, the community was categorized into Pinus densiflora - Quercus variabilis community and Pinus densiflora - Styrax japonica community.2. The importance value of Pinus densiflora, Quercus acutissima, Prunus sargentii, Styrax japonica, Quercus serrata, Quercus variabilis, Pinus rigida, Quercus aliena in tree layer were 83.20, 41.87, 30.93, 24.85, 23.27, 20.97, 20.28, and 9.46, respectively. The relative coverage of Stephanandra incisa, Quercus serrata, Styrax japonica, Parthenocissua tricuspidata, Rhododendron mucronulatum, Lindera obtusiloba, Prunus sargentii, Quercus variabilis, Indigofera kirilowii, Quercus acutissima, Lespedeza maximowiczii, and Acer pseudosibolianum in shrub layer were 9.62%, 9.55%, 9.18%, 7.85%, 6.18%, 5.25%, 4.82%, 4.15%, 3.98%, 3.98%, 3.55%, and 2.98%, respectively.3. According to size distribution map of diameter breast height of dominant species, the dominant species of Mt. Busosan was Pinus densiflora, and Quercus sp. such as Quercus acutissima, Quercus variabilis, and Quercus serrata may compete with the Pinus densiflora in the future.4. According to the ordination analysis of Mt. Busosan forest, Pinus densiflora - Styrax japonica community was found in moist site and Pinus densiflora - Quercus variabilis community was found in dry site.

A yeast strain, designated as JAF-11^T, was isolated from flower of Prunus mume Sieb. et Zucc. in Gwangyang, Republic of Korea. Phylogenetic analysis showed that strain JAF-11^T was closely related to Neodothiora populina CPC 39399^T with 2.07 % sequence divergence (12 nucleotide substitutions and three gaps in 581 nucleotides) in the D1/D2 domain of the large subunit (LSU) rRNA gene, and Rhizosphaera macrospora CBS 208.79^T with 4.66 % sequence divergence (25 nucleotide substitutions and five gaps in 535 nucleotides) in the internal transcribed spacer (ITS) region. Further analysis based on the concatenated sequences of the D1/D2 domain of the LSU rRNA gene and the ITS region confirmed that strain JAF-11^T was well-separated from Neodothiora populina CPC 39399^T. In addition to the phylogenetic differences, strain JAF-11^T was distinguished from its closest species, Neodothiora populina CPC 39399^T and Rhizosphaera macrospora CBS 208.79^T belonging to the family Dothioraceae by its phenotypic characteristics, such as assimilation of carbon sources. Hence, the name Neodothiora pruni sp. nov. is proposed with type strain JAF-11^T (KACC 48808^T; MB 850034).
