The promotive effect of Ca in semi-vitro culture of Oenothera biennis pollen was by and large identical to that of in vitro systems. This promotive effect became additive when boron was supplemented to the media and even more so if K was further supplemented. No such Ca action was observed then performed under the conditions of relatively low temperature. An uncoupling agent of ATP in respiration, DNP, inhibited the promotive action of B, but not that of Ca. The inhibitory effect of DNP was greater at low temperatures. IAA was rather inhibitory on pollen growth in semi-vitro culture, even much greater than it if DNP was supplemented to the IAA-containing media.

The purpose of this study is to examine the current status of vascular plants and naturalized plants growing in the Seongeup Folk Village in Jeju and to consider and compare their distribution patterns and the characteristics of emergence of naturalized plants in other folk villages and all parts of Jeju, thereby exploring measures to well manage naturalized plants. The result of this study is as follows.11) The total number of vascular plants growing in Seongeup Folk Village is identified to be 354 taxa which include 93 families, 260 genus, 298 species, 44 varieties and 12 breeds. Among them, the number of naturalized plants is 55 taxa in total including 22 families, 46 genus, 53 species, and 2 varieties, which accounts for 21.7% of the total of 254 taxa identified all over the region of Jeju. The rate of naturalization in Seongeup Folk Village is 15.5%, which is far higher than the rates of plant naturalization in Hahoi Village in Andong, Yangdong Village in Gyeongju, Hangae Village in Seongju, Wanggok Village in Goseong, and Oeam Village in Asan. Among the naturalized plants identified within the targeted villages, the number of those growing in Jeju is 9 taxa including Silene gallica, Modiola caroliniana, Oenothera laciniata, Oenothera stricta, Apium leptophyllum, Gnaphalium purpureum, Gnaphalium calviceps, Paspalum dilatatum and Sisyrinchium angustifolium. It is suggested that appropriate management measures that consider the characteristics of the gateway to import and the birthplace of the naturalized plants are necessary. In the meantime, 3 more taxa that have not been included in the reference list of Jeju have been identified for the first time in Seongeup Folk Village, which include Bromus sterilis, Cannabis sativa and Veronica hederaefolia. The number of naturalized plants identified within the gardens of unit-based cultural properties is 20 taxa, among which the rate of prevalence of Cerastium glomeratum is the highest at 62.5%. On the other hand, the communities of plants that require landscape management are Brassica napus and other naturalized plants, including Cosmos bipinnatus, Trifolium repens, Medicago lupulina, Oenothera stricta, O. laciniata, Lotus corniculatus, Lolium perenne, Silene gallica, Hypochaeris radicata, Plantago virginica, Bromus catharticus and Cerastium glomeratum. As a short-term measure to manage naturalized plants growing in Seongeup Folk Village, it is important to identify the current status of Cosmos bipinnatus and Brassica napus that have been planted for landscape agriculture, and explore how to use flowers during the blooming season. It is suggested that Ambrosia artemisiifolia and Hypochaeris radicata, designated as invasive alien plants by the Ministry of Health and Welfare, should be eradicated initially, followed by regular monitoring in case of further invasion, spread or expansion. As for Hypochaeris radicata, in particular, some physical prevention measures need to be explored, such as for example, identifying the habitat density and eradication of the plant. In addition, it is urgent to remove plants, such as Sonchus oleraceus, Houttuynia cordata, Crassocephalum crepidioides, Erigeron annuus and Lamium purpureum with high index of greenness visually, growing wild at around high Jeongyi town walls. At the same time, as the distribution and dominance value of the naturalized plants growing in deserted or empty houses are high, it is necessary to find measures to preserve and manage them and to use the houses as lodging places.

Osancheon creek is located in the southwest of the middle area in Korea. Weed community around the Osancheon creek, where various disturbances exert a bad influence directly on its community by human work or nature, was surveyed phytosocialogically. Our surveys have been accomplished from June, 2003 to September, 2003. Weed communities formed around the Osancheon creek were divided into several patterns and analysed. They have been divided into 8 communities. Community A: Humulus japonica community, B: Phragmites communiscommunity, C: Persicaria thunbergii community, D: Zi=ania latifolia community, E: Miscanthus saccharilflorus community, F: Echinochica crusgalli community, G: Typha orientalis community, H: Sataria viridis community. The flora surveyed in these communities was constituted of 19 families, 36 genera, 4 varieties, and 40 species. Wild plants such as Artemisia princeps var. orientalis Erigeron annuus, Bidens frondosa, Aeschynomene indica and Oenothera odorata were mostly light loving plants and higher resistant plants against the disturbance. Our result from the ranking all surveyed areas by the Bray-Curtis ordination method was very similar to the results from phytosocialogical table work.

This study aimed to identify mordant effects of Chestnut hulls. The color of post and pre-mordanted fabrics were measured in terms of H, V, C, $L^*$, $a^*$, $b^*$, and K/S values. In addition, color fastness and antimicrobial activity were evaluated. The pre-mordant concentration of Chestnut hulls for cotton, mercerized cotton and silk was optimized to 50% (o.w.f.) and 70% (o.w.f.), respectively. Post-mordant concentration of Chestnut hulls of mercerized cotton, silk and cotton was optimized to 50% (o.w.f.) and 90% (o.w.f.), respectively. The hue of fabrics was influenced by mordant methods, such as pre-mordant and post-mordant, slightly. Wet cleaning fastness of pre-mordanted cotton and mercerized cotton fabrics was higher than that of post-mordanted fabrics. The wet cleaning fastness of silk fabrics was not affected by the mordant method, and their fastness were proved to be excellent. The dry cleaning fastness of post-mordanted cotton fabrics was higher than that of pre-mordanted cotton fabrics. The dry cleaning fastness of mercerized cotton and silk was proved to be excellent regardless of mordant methods. The antimicrobial activity of Oenothera odorata jacquin dyed fabrics and Chestnut hulls mordanted fabrics was proved to 99.9%, and their excellent antimicrobial activity remained after wet and dry cleaning.
