The purpose of this study is to analyze the aesthetic characteristics of traditional Korean patterns appearing on fashion collections from 1990 to 2005. Traditional Korean patterns have been used as an important element to express a Korean image since the 1990s. Frequently used patterns included several kinds of geometric patterns, plant patterns(flower, peony, Four Gracious Plants), and Chinese character patterns. Specifically, since the 2000s, animal patterns such as tiger, Chinese phoenix, and giraffe which were not often used, plant patterns such as arabesque, peony, and flower, and a variety of Chinese character patterns appeared. For the expression techniques, while embroidery and printing was often used in the 1990s, they became varied into printing, beading, embroidery, gold and silver leaf, and hand painting after 2000 as a result of designers' active attempts. The aesthetic characteristics of fashion design with its focus on traditional patterns were analyzed. First, Chinese character patterns and phoenix pattern which were mainly used for a court suit, and show the excellence and unique originality of Korean culture. Second, traditional Korean patterns directly and indirectly imply symbolistic significance of lucky sign and illustrate the use of various lucky sign patterns. Third, traditional Korean patterns such as arabesque or peony were expressed by colorful embroidery to add decorative beauty. Finally, traditional Korean patterns reflect a naturalistic worldview and are completed finished as the design.

Combining ability study was carried out on the components of synchronization in maturity and determinate growth habit in mungbean, using 6$\times$6 diallel cross. Both additive and non-additive gene effects were found conditioning the inheritance of days to first flower, days between first pod and 90% pod maturity (DDd1), plant height from first pod stage to 90% pod maturity (DDhl, DDh2, and DDh3). Only non-additive gene action was important in degree of determination from first pod stage to 90% pod maturity (DDd2). While only additive action was important in plant height at first flower. The predominant additive gene action was observed in all traits but non-additive was significant in only DDd$_2$. For synchronization in maturity, determinate growth habit, and their components, the best combiners were NM92, VCl560D, and NM89, whereas the best indeterminate combinations were NM92 $\times$ NM89, NM92 $\times$ VCl560D, and NM92 $\times$ ML-5.

In order to develop a new skin whitening agent, approximately 100 plant extracts were evaluated for their inhibitory activities against melanin biosynthesis in cultured mouse melanocyte melan-a cells. As a result, seven extracts exhibited over 50% inhibition of melanin synthesis compared to control at a concentration of $20\;{\mu}g/ml$. In particular, Aster ageratoides Turcz. var. ageratoides (branch, root, aerial, flower; $IC_{50}$ = 17.3, 6.1, 13.6, $12.9\;{\mu}g/ml$, respectively) and Physalis alkekengi var. francheti (leaf, unripen fructus, aerial; $IC_{50}$ = 6.5, 28.3, $23.9\;{\mu}g/ml$) markedly inhibited melanin synthesis. In addition, tyrosinase activity was monitored by the measurement of dopachrome formation from the oxidation of L-3,4-dihydroxyphenylalanine. Extracts of A. ageratoides Turcz. var. ageratoides (flower) and P. alkekengi var. francheti (leaf) showed the most potent tyrosinase inhibitory activity. These plants might be the potential candidate sources in the development of novel skin-whitening products.

This study was conducted to investigate the effect of culture media and environment on PLB proliferation by using PLBs produced from leaf segments excised from shoot of Phalanopsis flower stalk. The fresh weight of PLBs propagated was higher in MS medium than in NDM (New Dogashima medium) or VW, but the condition of PLB was better in NDM medium. Natural additives of Coconut water, potato and apple were absolutely required for the PLB propagation. PLB propagation was better in solid medium than in liquid medium including cotton as support. Optimal sucrose concentration for proliferation was 10 g/L. PLB proliferation was very effective condition 14.3 $\mu$mol.s$^{-1}$ m$^{-2}$ in PPFD and $25^{\circ}C$.

Immature flowers and lateral buds of Neoregeria carorinae cv. Tricolor were cultured for micropropagation and the collecting times of materials, growth regulators and theirs concentrations, and cultural methods on the formation of adventitious buds and growth were investigated in this experiment The formation rate was the highest in immature flowers collected at 4weeks after flower bud differentiation and in buds at 7weeks after flower differentiation of adventitious buds. MS medium supplemented with 1.0 mg/L BA and 0.5 mg/L BA was the most favorable for the formation of adventitious buds. Solid medium was more effective for the formation of adventitious buds than liquid one. MS medium with 1.0 mg/L NAA was the most suitable for the rooting of regenerated shoot. Liquid medium was effective for the rooting of regenerated shoot than solid one.

Viral disease symptoms were investigated in the field grown Longiflorum hybrid cultivars, and the damages caused by infection with Lily mottle virus (LMoV) and Cucumber mosaic virus (CMV) were assessed by comparing growth of plants produced from seeds of Longiflorum hybrid cultivar both infected by artificial inoculation and free from infection with theses viruses. Dominant symptom caused by spotaneous infection with LMoV and CMV in the field was mottle combined with chlorotic stripe on leaves. LMoV developed brownish necrotic lesion on floral leaves. The incidence of viral disease by mixed infection with LMoV, CMV or Lily symptomless virus (LSV) in the filed grown Longiflorum hybrid cultivar, cultivated for more than 6 years, was 80 to 84 percent. In comparison with virus-free plants, plants doubly infected with CMV and LMoV by artificial inoculation decreased stem length by 14 percent and fresh weight by 38 percent. In conclusion, flower quality and the stem length of Longiflorum hybrid cultivar were affected by LMoV and CMV infection.

An effective pollinator was investigated based on visiting insects to confirm the pollination mechanism of Impatiens furcillata Hemsl. (cheo-jin-mul-bong-seon), an annual herb that is also a species endemic to Korea that has hardly been studied in relation to pollination ecology. The insects that visited the group of I. furcillata studied here consisted of four orders, 11 families, and 16 species; Hymenoptera had seven species (43.8%), Lepidoptera had four (25.0%), Diptera four (25.0%), and Hemiptera one (6.2%). Visiting insects were divided into those that took only nectar, those that took nectar and pollen, and those that took neither. Insects that are effective for pollination are judged considering the length and body type of their mouth parts, and Amegilla florea Smith (huin-jul-beol) is judged to be the most effective pollinator in the survey area. As a result of observing pollination behavior, when visiting a flower, A. florea, which extended its glossa, approached the front, landed on a wing petal of I. furcillata, crawled into the flower tube, and then backed up and reversed its steps, with pollen adhered to its back. The findings here present basic information about species biology related to both I. furcillata and A. florea.

To have more insight into the nature of plant, plant scientists carry out phytosociological studies on such plant species. The phytosociological studies on Tridax procumbens. Linn was carried out at Imo State University, Owerri, Imo State between the months of July and September, 2018. Tridax procumbens Linn grows abundantly in the areas under tropical climate and supported by a sandy-loam soil. Morphological features showed a range of variations. Phytosociological investigation showed a Tridax- Mitracarpus-Digitaria plant community. Tridax procumbens was positively associated with Digitaria horizontalis, Mitracarpus scarber and Vernonia cinera. The Inter-relationship of T. Procumbens was thus determined. This study therefore is a contribution to the general ecology of the plant. Phytosociological studies helps plant scientist to have more knowledge into the nature of plant species. This study is a contribution to the general ecology of the plant Tridax procumbens. The study also shows that it has close association with mitracarpus Scarber and Digitaria horizontalis. More work should be carried out to find out if these plant species flower and produce seeds at the same time or not.

GA4/7 spray, injection and several cultural treatments were applied to the greenhouse-grown potted hybrid larch(Larix decidua${\times}$leptolepis) grafts and field-grown European larch seedlings to induce early flowering. A treatment consisting of repeat-ed GA4/7 sprays, alone, was the most effective flower induction treatment for greenhouse-grown, potted larch grafts. Root pruning as a adjunct treatment did not show synergistic effects. Injection for potted grafts with GA4/7 was not useful approach in this study and it resulted in increased mortality. In the field experiment with 10-Year-old larch seedlings, repeated GA4/7 sprays in combination with root pruning or with plastic mulching appears to be useful and practical means for inducing larch flowers:

A new hybrid, Phalaenopsis 'Pink Marble' was made by the National Institute of Horticultural and Herbal Science, Rural Development Administration, in 2005. This hybrid was selected from self-crossed progenies of P. '21-1' (collected number) in 1999. In 2001, one line was selected based on the aspects such as flower color, leaf shape, flower stalk, and vigorous growth. Trials were conducted from 2003 to 2005 for evaluation and selection of this cultivar. 'Pink Marble' had a medium flowering habit and a dark pink spot (RHS, RPN74B) on white petal and sepal when fully opened. The number of flowers on each peduncle was 7.5, and flower diameter was 52.3 cm. The general impression of petals and sepals is a plate shape. The thick sepal could extend the long flowering time. The average length of leaf and peduncle were 16.5 cm and 6.8 cm, respectively. It had a half-erect leaf form, and was a fast-growing cultivar. This hybrid is relatively easy to clone.
