'Pattern' is of very unique nature in each and every country around the world, and its aesthetic feeling of 'pattern' has been handed down according to its nationality and cultural development process. That is, 'pattern' is ornament to symbolize each country's aesthetic standard or choice through some shape, reflecting social consciousness or religion philosophy. Mostly based upon literature survey and case study, this survey paper analytically compares oriental botanical pattern with occidental botanical figure, which has been influenced by Buddhism-Confucianism and Christian religion respectively. The results show that some patterns are commonly used in both area, while meaning differently in some cases: lotus (life), pomegranate (wealth and prosperity in orient, resurrection in occident), grape (fecundity in orient, wealth in occident), dangcho (fecundity in orient, victory in occident). And the other patterns look uniquely used either just in orient or only in occident. For instance, oriental area had its own patterns such as peony (meaning wealth and honour), peach (longevity), ume flower (happiness), orchid (fecundity); while occidental area used lily (purity), olive (peace), palm (victory), and so on. Interestingly, the botanical patterns were used as main patterns in orient whereas as minor in occident.

Phalaenopsis orchid is one of the most important flowers in flower industry. We conducted an experiment to find out the response of different concentration of chlorocholine chloride (CCC) for the in vitro regeneration of protocorm like bodies (PLBs) of Phalaenopsis 'Fmk02010'. We used five different concentrations of CCC and these were 0 (control), 0.01, 0.1, 1 and $10mgL^{-1}$ in modified MS medium and cultured for 42 days. We added two major salts ammonium nitrate ($412.5mgL^{-1}$) and potassium nitrate ($950.0mgL^{-1}$) to the MS medium for the modification. Maximum numbers of PLBs were found from media with $0.01mgL^{-1}$ of CCC (15.667) and maximum fresh weight (0.211 g) as well. The 100% PLB formation rate was also found from $0.01mgL^{-1}$ of CCC. We found 58.83% variation in number of PLBs ($R^2=0.5883$) and 47.44% variation in fresh weight ($R^2=0.4744$) to the different CCC concentrations. Our study suggested that increase in the CCC concentration negatively affect the PLBs organogenesis of Phalaenopsis. We can suggest that the addition of very low concentration of CCC in plant culture medium can increase the number, formation rate and fresh weight of PLBs of Phalaenopsis.

In order to improve quality and to accelerate blooming time in potted Oncidium 'Aloha', foliar spray of $GA_3$, BA, zeatin, and kinetin were applied on June 1 and June 15. The plant growth regulators did affect the improvement of number of peduncles, pedicels and florets, and shortened flowering time. Especially, number of peduncles and of florets were remarkably increased by foliar application of BA solution. And the flower opening time were shortened 26 days by 100mg/L BA treatment compare with control.

A New Cymbidium variety "Yellow Evening" was developed from a cross between "Oji" and "Valley Flower Cherry Life" followed by seedling and line selections at the National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA) in 2004. After investigation of the characteristics and selection for 9 years (1996-2004), it has been selected specifically pot orchid flower. "Yellow Evening" has medium plant height and semi-erect peduncle. It has medium flowering habit and brownish yellow flowers (RHS, Y11B: petal and sepal) with grayed purple GP183A) spot on lip, when fully opened. Each peduncle has 15.3 flowers with diameter of about 7.4 cm. It has adequate peduncle height, with some curved and spreading petal and sepals. Under optical culture conditions, it started to bloom early-winter (November).

Effects of plant growth regulators and anti-oxidants for rapid multiplication of Cymbidium kanran were investigated. The best gelling agent was 2.5 g/1 gelrite which needed less quantity (about 28%) and half price than 9 g/1 chemi-cal agar. Undefined edible agar was only a little bit worse than chemical agar in growth, but the price was half as much as the latter. The higher concentration of BA and NAA, the deeper browning of medium that prevented from performing its functions of plant growth regulators. Polyvinylpyrrolidone (M.W. 40,000) was the most effective anti-oxidant other than ascorbic acid, aspartic acid, and rutin in protecting the browning of medium, enhancing the effect of plant growth regulators, and thus prolonging the subculture cycle. Vigorous seedlings were obtained by 0.1∼1.0 mg/1 BA,0.1 mg/1 NAA and 1 g/1 polyvinylpyrrolidone treatments. Therefore, the best result for growth and econo-mic aspects in rhizome culture of Cymbidium kanran were obtained by using MS basal medium with 2.5 g/1 gelrite, 1 g/1 polyvinylpyrrolidone, 0.1∼1.0 mg/1 BA and 0.1 mg/1 NAA.

Growth and flowering of Cymbidium 'Red Fire' and 'Yokihi' plants were examined in a greenhouse with cooling systems in summer, and with night interruption (NI) lighting in winter as a forcing culture system. The greenhouse was divided into two sections with separate cooling controls during the summer season. One section was cooled by a mist system (mist), while the other section was cooled by a shade screen (shade). During the winter, the greenhouse was redivided into three sections within each cooling system. Plants were grown with NI either at a low light intensity of $3-7{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$(LNI) or a high l ight intensity of $120{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$(HNI) u sing h igh-pressure sodium l amps during the 22:00-02:00 HR. The control plants were grown under 9 h short-day condition. NI for 16 weeks and cooling for 9 weeks were employed twice during the 2 years of the experimental period. The air temperature was approximately $2^{\circ}C$ lower in the mist than in the shade and the relative humidity was 80 ${\pm}5%$ in the mist compared to $55{\pm}5%$ in the shade. The daily light integral in the mist section was 48% higher than in the shade section. The time from initial planting to flowering pseudobulb emergence decreased with both LNI and HNI for both cultivars, regardless of the cooling treatments. Under NI conditions, however, between 60% and 1 00% of plants of both cultivars flowered in the mist, whereas no or 20% of 'Red Fire' or 'Yokihi' plants, respectively, flowered in the shade treatment over 2 years. Plants grown under the mist had bigger pseudobulbs than those grown in the shade under both NI treatments. These results show that commercial use of NI in winter and a mist cooling system in summer would decrease crop production time to 2 years and increase profits in Cymbidium forcing culture.

Anoectochilus formosanus, commonly known as "Jewel Orchids", which has been used in traditional folk medicines for feber, pain, and diseases of the lung and liver in Taiwan. We artificially cultured Anoectochilus formosanus plantlet by using the bioreactor culture system for this study from Anoectochilus formosanus. Previously, several studies have been reported on pharmacological activities of lipid-metabolism, hepatoprotective activity, anti-tumor activity and immuno-stimulating effects but other efficacy were not well known as a cosmetic ingredient for skin care. In this study, we investigated the effect of melanogenesis in B16 mouse melanoma cells and lipid droplet accumulation in 3T3-L1 preadipocytes about Anoectochilus formosanus plantlet extract. We report that Anoectochilus formosanus plantlet extract inhibits the cytoplasmic lipid droplet accumulation through adipogenic differentiation of preadipocytes as well as inhibition of tyorsinase activity and melanogenesis. As a result, our findings indicate that Anoectochilus formosanus plantlet extract may be the potential natural ingredient for whitening and slimming cosmetic products.

Two orchid species of Calanthe discolor Lindl. and C. discolor for. sieboldii (Decne.) Ohwi, which have different form flower color and size. They were crossed in mid April by artificial pollination, and the F1 hybrid seeds were collected mid October. Germination of seeds was investigated on pre-treatment of seeds and under the various environmental conditions. Germination was promoted by moisture absorption and ultrasonic treatment of seeds. Dark culture of F1 hybrid seeds enhanced germination and protocorm formation, and development into seedlings compared with light culture. Although, plant growth regulators such as NAA and BA had a slightly promotive effect on seed germination and protocorm growth, regenerated seeding were showed abnormal growth patterns. Regenerated F1 hybrid plantlets were successfully transferred to pot.

This study investigated the in vitro symbiotic seed germination of the achlorophyllous orchid, Gastrodia elata, using a new Mycena species. A leaf-disc ($2{\times}2cm$) of Quercus accutissima was inoculated with either of the two fungal species, NIFOS101 (NCBI accession number KY449288) or KFRI1212 (HQ662845), following which it was placed on water agar medium, prior to sowing seeds of G. elata. After 20 days of symbiotic culture, NIFOS101 and KFRI1212 germinated 94% and 70% of G. elata seeds, respectively, although the initiation of protocorm development was induced much earlier by KFRI 1212 than by NIFOS101. Furthermore, the NIFOS101 mycelia grew much faster than KFRI 1212 at all temperatures tested. A phylogenetic analysis using the internal transcribed spacer (ITS) sequences showed that NIFOS101 belonged to a clade with M. purpureofusca, which completely differed from the clade with KFRI1212. This study not only identified a new fungal species, NIFOS101, which improved the rate of symbiotic seed germination up to 94% as compared to KFRI1212 (70%), but also revealed that G. elata required a broad taxonomic range of fungi for its symbiotic germination.
