In vitro flowering system may minimize the confounded influence of non-floral meristem parts of plants in studying the relationship of a given treatment and flowering responses. We have induced flower buds from plantlets regenerated from zygotic embryo-derived somatic embryos of ginseng, which circumvented the normal 2-year juvenile period before flowering. The result suggests that the adulthood of ginseng root explants in the experiment previously conducted by Chang and Hsing (1980; Nature 284: 341-342) is not prerequired to flowering of plantlets regenerated through somatic embryogenesis. We have also induced flower buds from elongated axillary brandches from cotyledonary nodes by culturing ginseng zygotic embryos, seedlings, and excised cotyledonary nodes. It was found that 6-benzyladenine (BA) supplemented to the medium was essential for flowering, whereas abscisic acid (ABA) was inhibitory. Gibberellic acid(GA3) was also required for flowering when ABA was present with BA in the medium. The results suggest that cytokinins, gibberellins, and inhibitors play primary, permissive, and preventive roles, respective-ly, in the induction of flowering of ginseng. Tran Thanh Van (1980; Int. Rev. Cytol., Suppl. IIA: 175-194) has developed the "thin cell layer system" in which the induction of shoots, roots, or flower buds from epidermal layer explants were controlled by culture conditions and exogenous growth regulators in the medium, Utilizing the thin cell layer system, Meeks-Wagner et al. (1989; The Plant Cell 1: 25-35) have cloned genes specifically expressed during floral evocation. However, the system is too tedious for obtaining a sufficient amount of plant materials for biochmical and molecular biological studies of flowering. We have developed a garlic callus culture system and one obvious advantaging over the thin cell layer system is that an abundant cells committed to develope into flower buds proliferate. When the above cells were compared by two-dimensional gel electrophoresis with those which have just lost the competence for developing into flower buds, a few putative proteins specific to floral evocation were detected. The garlic callus culture system can be further explored for elucidation of the molecular biological mechanism of floral evocation and morphogenesis.hogenesis.

Vitamin U levels in 26 kinds of food plants are well known to healthy vegetables in Asian or Western countries were determined. Spinach showed the highest level of 452.04 mg/kg and in order Pack-choi (343.18 mg/kg) > Kale (234.18 mg/kg) > Somssukbujaengi (197.66 mg/kg) > leaf mustard (196.21 mg/kg) > aralia bud (192.50 mg/kg)> broccoli (189.03 mg/kg) >Asparagus (187.35 mg/kg). Among Korean wild medicinal plants, Sumssukbujaengi showed the highest value followed by Sanmanul (a kind of wild garlic) level of 143.46 mg/kg. For Chinese cabbages and cabbages, vitamin U showed different levels according to the parts of plant such as core, middle, outward leaves. In both samples, middle parts of leaves including midribs contained the highest level of vitamin U. The level of vitamin U was dependent on the part of the plant sample and cultivars. Leaf parts of turnip and white radish showed higher value of 84.82 mg/kg and 124.62 mg/kg than those of roots which were in order of middle (112.39 mg/kg), top (84.84 mg/kg) and bottom (84.61 mg/kg) portions in the white radish. In the analysis of amino acids, we didn't find either distinctive relationship between methionine and vitamin U synthesis or significant connection various free amino acids and vitamin U level in food plants.

Farnesyl diphosphate synthase (FPS) catalyzes the biosynthesis of farnesyl diphosphate, a precursor for many important terpenoid products. A cDNA encoding FPS was first isolated from Allium sativum (AsFPS) using rapid amplification of cDNA ends (RACE) PCR. The sequence of AsFPS contains an open reading frame encoding a protein of 341 amino acids with a predicted molecular mass of 39.61 kDa. Alignment of AsFPS deduced amino acid revealed high identities with other plants ranging from 79% to 85% and showed 2-high conserved aspartate-rich motifs known to be important for FPS activity. Furthermore, AsFPS expression was stronger in the green organs such as bulbils, scapes, leaves, stems, but weaker in bulbs and roots than on-green organs of A. sativum.

Taurine content in Korean foods of plant origin was determined for 118 commonly used food items including cereals, potatoes, pulses, nuts, seeds, vegetables and fruits. Taurine concentration in food sample was analyzed using an automated amino acid analyzer(Biochrom 20, Pharmacia LKB) based on ion-exchange chromatography. Taurine was frequently detected in plant kingdom in much lower concentrations(1/100~1/1000) than those found in marine lifes and mammals. Glutinous rice, glutinous millent and sorghum did not contain taurine, while 0.7~3.9mg taurine/100g dry wt were detected in rice, barley and their products. Potatoes and sweet potatoes contained 0.3~1.2mg taurine/100g wet wt, and seasame seeds, perilla seeds, almonds, walnuts and gigko nuts contained 0.7~3.0mg taurine/100g wt. Taurine concentration was undetectable in most of the pulses, and in a large number of vegetables. Garlic bulbs, eggplants, green peppers, lotus roots, and cabbages have a relatively high level of taurine(around 1mg taurine/100g wet wt) among vegetables. Taurine was absent or found in very low levels(<1mg taurine/100g wet wt) in most of the commonly used fruits.

This study was to investigate the perception about the popularization of temple food, known as health food and adult disease prevention food as an object of total 248 residents in Youngnam region. From the result of this research above, it may be summed up as follows. This study has found out that the advantages of temple food showed the statistical significant difference according to the gender, age, and size of family (p<0.01). The reason 'because of health food' (66.7%) had such high percentage. The necessity of popularization of temple food had big difference according to the gender and age (p<0.01). In addition, this study has shown the statistical significant difference in the cooking form for popularization by age, and future improvement for popularization by age and size of family (p<0.001). And, this study has found out that the 'traditional way as it is' (57.3%) was high in the cooking form, and 'use of various materials' (27.4%) in the improvement. Furthermore, the necessity of using meat for temple food had significant difference according to the gender and age, and 'need' (33.9%) showed rather higher tendency. The necessity of using osinchae, five forbidden pungent roots like garlic, green onions, Korean leeks, wild chives, and asafetida had significant difference according to the gender, age and size of family (p<0.05, P<0.001). The 'need' (61.3%) was considerably high. Based on the above results, general customers thought that the need for popularization of temple food and use of osinchae was very positive.

The purpose of this study was to investigate the preferences, consumption, and eating frequencies of housewives for commercialized traditional basic side dishes. The investigators visited 18 food markets and questionnaires were distributed to 464 housewives in the Busan area. The number of basic side dishes being sold at the markets were in the order of seasoned dried radish (17 markets; mk), salted garlic stalk (15 mk), braised black soy beans (14 mk), braised peppers and dried anchovies (13 mk), and braised lotus roots (12 mk). The housewives' order of preferences was for stir-fried dried anchovies, braised peppers and dried anchovies, braised seasoned beef, salted perilla leaf, and perilla leaf kimchi equal to seasoned sea lettuce, respectively. The order for eating frequency was stir-fried dried anchovies, braised peppers and dried anchovies, salted perilla leaf, and perilla leaf kimchi, respectively. Salted perilla leaf, perilla leaf kimchi, braised crab preserved in soy sauce, salted bean leaves, seasoned dried radish, and seasoned crab were either occasionally or frequently purchased by over 40% of the women. However, the reasons they did not purchase these products included: the excess use of chemical seasonings, unsanitary, unreliable cooking process, unreliable the origin, and high price, in the respective order. If the commercialized traditional basic side dishes were improved to eliminate these problems, 52.2% of the housewives would buy the products, and 65.6% anticipated increasing their use of these products in the future.

In order to determine the effects of cytokinin and auxin on organ formation from tissue of garlic cloves, leaf blades and basal tissues contained meristem of garlic (Allium sativum L.) cloves harvested in 1979 (old cloves) and 1980 (new cloves) were explanted on a MS medium contained various levels of BA ($N^6$-benzyl amino purine), NAA (naphthalene acetic acid), and 2, 4-D (2, 4-dichlorophenoxyacetic acid). And some of the new cloves were explanted on a media contained BA and NAA after chilling treatment at $4^{\circ}C$ for 10, 20, 30 and 40 days. 1. In a culture of leaf blades of old cloves, shoots were differentiated on a medium supplemented with 2mg/l of BA and NAA. 2. Callus was grown as a quite straw-coloured globular mass on a medium contained 0.2 or 2mg/l 2.4-D. 3. As subcultures of globular calli, shoots and roots were differentiated on a medium contained 2mg/l BA and 0.5 or 1 mg/l NAA, whereas no shoots was shown on a conterol. 4. Shoots were differentiated in a culture of leaf blades of new cloves, but they were not in an old cloves in control, and better effect was shown on a medium contained 2mg/l BA and 1mg/l NAA. However shoots were no differentiated from leaf blades chilled at $4^{\circ}C$ for 30 or 40 days at the same condition. 5. Large numbers of adventitious shoots could be obtained from basal region of garlic cultured on a medium contained 1mg/l BA and 4mg/l NAA, or 2mg/l BA and 2mg/l NAA.

The purpose of this study was to understand dietary culture of the Buddhist priesthood in Seoul and Kyongnam. This survey was carried out through questionnaries for menu, pretreatment, seasoning and recipe and the subjects were 26 temples and hermitages. Foods of the Buddhist priesthood were divided into staple food and side dish. The results of this study can be summarized as follow: 1. Staple foods of the Buddhist priesthood divided into cooked rice, gruel, noodle and Sujebi. Main materials of cooked rice and gruel were rice, noodle and Sujebi were wheat flour. Menues of staple foods were used white cooked rice, white gruel, wheat noodle and wheat Sujebi, respectively. Soups of noodle and Sujebi were used mushroom and seaweed. 2. Side dishes of the Buddhist priesthood divided into soup(국), stew(찌게), hard-boiled food(조림), steaming food(찜), raw vegetables(생채), cooked vegetables(나물), roast vegetables(볶음), pan fried food(전), baked(구이), wrapped rice(쌈), raw fish(회), Mook(묵). Vegetables divided into green-steam vegetables, edible roots, fruit vegetables, edible mountain herbs and seaweeds. A great difference of used for vegetables had been observed kinds of side dishes. Main materials of wrapped rice, raw fish and Mook was lettuce, raw mushroom and acorn, respectively. Seasonings were red pepper, garlic, green onion and sesame oil.
