Some 420 species of higher fungi were collected from the Mt. Paekdu, Songwha river and their adjacent areas from 28th July 12th of August, 1991 and identified to 2 subdivisions, 4 classes, 2 subclasses, 12 orders, 51 families, 141 genera and 336 species. The dominant species were Clitocybe gibba, C. clavipes, Cystoderma amianthnum, Hygrocybe flavescens, H. miniata, Russula cyanoxantha, R. emetica, Lactarius lignyotus, L. torminosus and Phellinus igniarus.

The goal of this research was to develop the effectiveness of in vitro culture method for A. formosanus and study the environment in vitro conditions affecting on growth. The first series of experiments were examined to investigate the response of three different basal media, MS (Murashige and Skoog, 1962), Knudson (KC; Knudson, 1946) and modified hyponex on growth and multiplication during in vitro culture. Multiple shoot proliferation was induced in shoot tip explants on Hyponex (H3) media supplemented with BA (1 mg1$\^$-1/) or TDZ (1-2 mg1$\^$-1/). Addition of activated charcoal (1%) to the TDZ containing medium promoted rapid shoot tip proliferation (11.1 shoots per explant) but the same medium had an opposite effect resulting in poor proliferation in the nodal explants. However, the regenerated shoots had slow growth rate and failed to elongate. This problem was overcome by transferring the shoot clumps to a hormone free H3 media supplemented with 2% sucrose and 0.5% activated charcoal. Using bioreactor culture for scaling up was also shown the best way for multiple shoot induction and growth of this plant. The second series of experiments was studied to investigate the effect of physical environment factors on growth of in vitro plantlets. The Anoectochilus formosanus plantlets were cultured under different air exchange rate (0.1, 0.9, 1.2h$\^$-1/), without sucrose or supplement 20g.1$\^$-1/ (photoautotrophic or photomixotrophic, respectively), and different photosynthesis photon flux (40, 80, 120 ,${\mu}$mol.m$^2$.s$\^$-1/- PPF). Under non-enrichment CO$_2$ treatment, slow growth was observed in photoautotrophical condition as compared with photomixotrophical condition on shoot height, fresh weigh and dry weight parameters; High air exchange (1.2.h-l) was found to be inadequate for plant growth in photomixotrophical condition. On the contrary, under CO$_2$, enrichment treatment, the plant growth parameters were sharply (visibly) improved on photoautotrophic treatments, especially on the treatment with air exchange rate of 0.9.h-1. The growth of plant in photoautotrophic condition was not inferior compared with photomixotrophic, and the best growth of plantlet was observed in treatment with low air exchange rate (0.9.h-1). Raising the PPF level from 80 to 120${\mu}$mol.m$\^$-2/.s$\^$-1/ decreased the plant height, particularly at 120${\mu}$mol.m$\^$-2/.s$\^$-1/ in photoautotrophic condition, fresh weight and dry weight declined noticeably. At the PPF of 120${\mu}$mol.m$\^$-2/,s$\^$-1/, chlorophyll contents lowed compared to those grown under low PPF but time courses of net photosynthesis rate was decreased noticeably. Light quality mainly affected morphological variables, changes of light quality also positively affected biomass production via changes in leaf area, stem elongation, chlorophyll content. Plant biomass was reduced when A. formosanus were grown under red LEDs in the absence of blue wavelengths compare to plants grown under supplemental blue light or under fluorescent light. Stem elongation was observed under red and blue light in the present experiment. Smaller leaf area has found under blue light than with other lighting treatments. Chlorophyll degradation was more pronounced in red and blue light compared with white light or red plus blue light which consequent affected the photosynthetic capacity of the plant. The third series of experiment were studied to investigate the effect of physical environment factors on growth of ex vitro plants including photosynthesis photon flux (PPF), light quality, growing substrates, electrical conductivity (EC) and humidity conditions. In the present experiments, response of plant on PPF and light quality was similar in vitro plants under photosynthesis photon flux 40${\mu}$mol.m,$\^$-2/.s$\^$-1/ and white light or blue plus red lights were the best growth. Substrates testing results were indicated cocopeat or peat moss were good substrates for A. formosanus growth under the greenhouse conditions. In case of A. formosanus plants, EC is generally maintained in the range 0.7 to 1.5 dS.m-1 was shown best results in growth of this plant. Keeping high humidity over 70% under low radiation enhanced growth rate and mass production.

This experiment was conducted to investigate the effects of turf grass growth to seedling rates and bed soil types. The results of this experiment were summarized as follows; the more increasing the seedling rates, the plant height and leaf length were longer, but the number of leaf and number of branch were fewer. In case of transplanting of turf grass seedling by rice transplanting machine, it might be considered that the proper alternative bed soil was sandy loam soil with regarding to the economic aspects. The maximum seedling rate of turf grass in the seedling tray for rice was 1,000 of seedling amount due to the nutrient competition with intensive seedling. As the results indicated, it might be recommended that the proper alternative bed soil was sandy loam soil with 1,000 of seedling rates in case of transplanting of turf grass seedling by rice transplanting machine.

Various kinds of plants were collected all over the Tsangbaishan from 1956-2000 . they were identified and classified into anticancer plants. According to the result they were composed of 61 families, 129 genera and 162 species. Among them, 10 species of anticancer plants is discussed about their pharmacologic evalution and application.

The first record of buckwheat in Korea was revealed from an old Korean book, "Hyangyakguguebbang(鄕藥救急方)" written in the era of king 'Gojong' who governed the country from AD 1236 to 1251 in the Korea dynasty. Buckwheat in Korea has been known to be introduced from China in 5th -6th century. One of the most famous buckwheat noodles, 'Naengmyeon' had been used popularly among the people in the Korea dynasty. It is true that buckwheat had been cooked and sold in temples during the Korea dynasty, and was regarded it as one of the temple foods at that time. Buckwheat has been cultivated as an alternative crop and buckwheat grains have been used as a hardy plant when the food situation for people was lacking in Korea. Buckwheat was an important crop in a slash-and-burn field(shifting cultivation) of the mountainous area in Kangwon province. A written history of the shifting cultivation in Korea was found in an old book "Taekriji" which was written by Lee, Jung-Hwan in the Chosun dynasty. The area and number of households of shifting cultivation in Korea was 40,000 ha and 135,000 household, respectively in 1973. Fifty to sixty kilogram of buckwheat grains per la was harvested at an altitude of 600 - 800m. Folk songs which have been sung among the people in shifting areas include buckwheat meal. One of the folk songs for buckwheat is as follows; "they do not eat rice with or without waxy property but eat buckwheat mixture." Since 1974, shifting cultivation has been legally prohibited to allow revegetation of destroyed mountains and rehabilitation of woodlands in Korea. Buckwheat has been traditionally marketed as noodle or flour for the manufacture of noodles, and also as groats for food in Korea. Consumption in markets has increased over the past several years. Buckwheat grains are mainly consumed in the form of noodles in Korea. However, many people have recently pursued a desire to make food products of high quality in processing buckwheat materials for health reasons.

The chlorophyll fluorescence combined with the O-J-I-P transients were examined in the leaves of the crinum plants (Crinum asiaticum var.japonicum BAK.), in order to satisfy the demand for rapid in vivo measurement of vitality, and to apply easily to approach questions of economical interest concerning the plant vitality. The photosynthetic efficiency, Fv/Fm, of crinum plants dramatically decreased depending on temperature drop in winter. In summer, the Fv/Fm values was lower in day time than at dawn and night, suggesting that photosynthetic efficiency is chronically photoinhibited in day time. In winter, there was no prominent diurnal fluctuations of Fv/Fm values. However, based on the O-J-I-P transient, PI$\_$NO/ and SFI$\_$NO/ dramatically increased at noon in summer, and $\psi$ο/(1-$\psi$ο) diurnally fluctuated in winter. These results indicated that vitality indexes such as PI$\_$NO/, SFI$\_$NO/ and $\psi$ο/(1-$\psi$ο) can be used as the indicators for in vivo measurement of environmental stresses.

Bottle gourd, Lagenaria siceraria, is one of the oldest cultivated plants. To bigin with, its fruit was used as a complete liquid bottle or container. It was a very widespread cultivated plant in prehistoric times, for example (there) is a report from Peru as early as between 13,000 B.C and 11,000 B.C. The dug-out finds in Japan proved to be about 95,000 years old according to the /sup 14/C analysis. The bottle grourd was the most important plant before the invention of pottery in many areas of Asia, New Guinea, Polynesia, America, and Africa. I would like to suggest that there should be "The Bottle Gourd Age" prior to the Pottery Age. Bottle gourds are also used for various purposes such as food, masks, pipes, musical instruments, medicine, symbols, artistic products and also as penis-sheaths of men's attire. Their purposes number more than 220 including 70 varienties of containers or bottles. I consider that its utilization should be called a culture, as it were, "The gourd culture." The shape and the size of the fruit of bottle gourd have a larger variety than those of any other plant. As for the size, it is reported that they range from those that are shorter than 3cm to those that are ovoid and longer than 60cm in diameter. With regard to the shape of its fruit, the bottle gourd can be classified into 7 groups and even more than 30 races, considering the difference of the size. The seeds are so variable without two horn-like projections, with smooth surface or longitudinalines, white or brown, with smooth corky margin. Generally, it seems that there is no correlation between seem shape and fruit shape. My study shows that the seeds of gourd. My study shows that the seeds of gourd in Asia are so simple in shape and in color except for the size. But the seeds of those in Africa are various and seem to be beyond the confines. Explaining the great diversity of the seeds of those in Africa therefore, they appear to have no correlation among the types of fruit of the bottle gourd with African origin. It might be supposed that another 4 wild Lagenaria spp. distribute only in Africa. The intraspecies hybrid is confirmed between the bottle gourd, Lagenaria siceraria, and wild L. spehaerica. And Fl hybrid is sterile: it has no fertility. However, even though the shapes of the fruit and the seeds are different, they can cross with each other. Moreover, their hybrids grow up to be extremely vigorous and have normal fertility. Fruit shapes of Fl plants are similar to those of their parents, if they have the same character. Whereas, the fruit shape often became different from each other when the cross occurs between those with different fruit shapes. It is shown that dumbbell shapes, HYOTAN in Japanese, is recessive while its bitterness is dominant. Thus the character of F2 hybrids Is segregative. I'll give further particulars of the heredity of the groud in my lecture.

In higher dicotyledonous plants, the floral organs are arranged in four different whorls, containing sepals, stamens and carpels. petals, stamens and carpels. The specification of floral organ identity is explained by the ABC model (Weigel and Meyerowitz 1994). expression of an A-function gene specifies sepal formation in whorl 1. the combination of A-and B-function genes specifies the formation of petals in whorl 2, B-and C-function genes spesify stamen formation in whorl 3, and expression of the C-function alone determines the formation of carpels in whorl 1. A-, B-, C-function genes have been isolated from many plant species and most of them belong to the family of MADS-box genes encoding transcription factor. In contrast to the flower of higher dicots, the perianths of genseng plants have three whorls of almost identical petaloid organs. van Tunen et al. (1993) proposed a modified ABC model, exemplified with tulip. In this model, B-function genes are expressed in whorl 1 as well as whorl 2 and 3, theefore the organs of whorl 1 and whorl 2 have the same petaloid structure. They proposed this model with the molphological data of wild type and mutant flowers of tulip, however, there are no molecular data. To date, B-function genes were isolated several grass plants, rice, wheat and maize. However, grass plants have highly derived flowers, without well-developed perianths. To find out how the ABC model has to be modified for the Genseng plants, we have cloned and characterized orthologs of A-, B-, C-function genes from genseng.
