  • Astragalus membranaceus has flowers that are similar to that of the legume family, but shows poor bearing when self-pollination is induced. Thus, this study was carried out observing the ripening procedure of pistils and stamens and development stages of pollen in the context of the birth and growth of the flower. As to the bearing of the flower of A. membranaceus, few pod setting and 13% pod setting were observed when self-pollination is induced by paper-bag covering or artificial pollination treated respectively. The result indicates that A. membranaceus is a cross-pollination plant. A pistil grew faster than a stamen until just before blooming. The flower size was about 17.0mm$\times$4.0mm. Pistils and stamens had the same length after flowering. Pollen mother cells passed through meiosis and mitosis when its length reached around 3.5mm, thus creating the tetrade when 4 mm long. Pollen attained full growth when the bud was about 10mm long. An anther was found to tend to dehisce when the length of a bud reached around 12.0mm. As to the shape of pollen, about 70 % were normal. 1% and 30 % were small or empty pollen respectively. The result indicates that pollen of A. membranaceus attains full growth just before anther dehiscence which occurs before blooming while pistils grow faster than stamens until before flowering.

  • Tilia amurensis is an important honey plant. As T. amurensis mainly distributes mountainous area with various elevations in Korea, accurate prediction of blooming time at the different elevation would benefit forest beekeepers. In this study, we measured time-dependent blooming progress of T. amurensis in Mt. Gariwang area ranging from 500-1500m. Additionally we collected blooming data from web and published literatures and estimated the variation of blooming time relative to the geographic locations. Flowers began to bloom from July 6 to July 22 with full blooming on July 14 in location where elevation is 638m in Mt. G ariwang area in 2021. Based on these databases, a growing degree day (G DD) model was developed for prediction of T. amurensis blooming progress using average daily temperatures. Using the starting date of G DD accumulation of January 1 and base temperature of 5 ℃, blooming period ranging from 10% to 90% of cumulative blooming rate was estimated as 860-1198 degree days (DD). This corresponded to the beginning to the end of July in Mt. Gariwaning area in 2021. This model could explain the phenological variations of T. amurensis flower blooming possibly affected by elevation within geographic area, latitude or year relative to the climate change, and aid forest beekeepers for better timing of nectar foraging by honey bees.

  • This experiment was conducted to examine the effect of injecting cool air from an abandoned mine during the summer time for the growth of Doritaenopsis. The air temperature of abandoned mine in Boryeong was $12{\sim}14^{\circ}C$. The day and night temperatures were set at $22^{\circ}C$ and $20^{\circ}C$, respectively, from June to August in the experimental plastic house. This temperature range was within the suitable range for floral induction in Doritaenopsis. Average outside temperature was $28.4{\sim}32.8^{\circ}C$. The 3% of the crop developed flower stalk in 20 days after the treatment initiation, 65% in 45 days, and 100% in 90 days. The flower stalk length was short (48.7cm) in 30 days and long (62.4cm) in 60 days of treatment. The flower stalk length became longer as time passed. Flower spike and number of florets per stalk displayed the same tendency. Number of nodes was 6~7 and was not affected by the period. The first blooming appeared on 15th of September at 45 days and blooming tended to appear late as the period is lengthened. When the cool air from an abandoned mine was injected, the crop formed flower stalk three months earlier and bloomed four months earlier than the untreated control.

  • A Cymbidium variety 'Snow Bell' (C. kanran ${\times}$ C. Jack Frost) was developed at the National Institute of Horticultural & Herbal Science, Rural Development Administration in 2011. A cross between C. kanran with small-sized greenish colored flowers and C. Jack Frost with bright pink colored flowers, was conducted in 1999. Based on flower color, leaf shape, flower stalk, and vigor one line was selected. Evaluation and selection trials were conducted from 2006 to 2010. 'Snow Bell' has a light pink sepal (RHS, R56D), red lip (R56A) and a leaf length of 47.5 cm. The average number of flowers on each peduncle is 13.8 and the flower diameter is 6.2 cm. The characteristics of petals and sepals show some incurve and some spreading. 'Snow Bell' has a vigorous growth and a round flower. It has an adequate peduncle height of 50.7 cm compared with leaf length of 47.5 cm, and start blooming in December. In electronic nose analysis, the degree of fragrance between 'Snow Bell' and the C. kanran was similar and both of them showed strong scents, although they had different fragrance patterns.

  • Soybean, azuki-bean and mungbean were cultivated at different growing conditions, May 10, June 9, July 9 seeding, and May 10 seeding-short day treatment, to investigate the distribution of flowering date and the variation of pod/flower ratio. The growth habit type of the soybean variety used was determinate, but the azuki-bean and mungbean varieties used showed indeterminate growth habit. The pod/flower ratio ranged 38 to 48% for soybean, 23 to 34% for azuki-bean and 46 to 60% for mungbean along with growing conditions. Flower abscission for soybean and mungbean, and pod abscission for azuki-bean affected more on the number of matured pods. Soybean showed once full blooming period, but azuki-bean and mungbean showed two or three times full blooming period except July 9 seeding plot through the whole growing period. Flowers bloomed just after every full blooming period showed lower value of pod/flower ratio and higher pod/flower ratio was obtained from flowers bloomed before or far after full blooming at plots seeded May 10 and June 9 in three pulse crops. Most full blooming period of soybean coincided within 5 days near the terminal leaf appearance date, and number of flowers bloomed before terminal leaf expansion and matured pods from these flowers were major in every soybean plant at all growing codition plots. No relations were found between terminal leaf appearance and flowering or pod setting patterns of azuki-bean and mungbean.

  • In this study, it is investigated the types and the compounding method of flower patterns and the uses of flower patterned fabrics in Chosun Dynasty. Research was done through the references of exhumed clothing during 16-17th century. Our ancestors had used the various flower patterns based on Buddhism, Taoism and Confucianism onto the fabrics. The flower patterns on the fabrics were expressed with the other patterns such as treasure patterns, letter patterns or bird patterns. And the flower patterns symbolized the various good meanings such as longevity, integrity and prosperity etc. In the order of the percentage, the types of the flower patterns were shown Lotus(27.31%), Arabesque(26.85%), Japanese apricot(14.81%), Peony(8.79%), Flowering plants(6.94%), Chrysanthemum(6.01%), Pomegranate(2.31%) patterns and so on. Especially the Lotus pattern was shown up most frequently. That of shape was designed as blooming(開花), full bloom(滿開) and the side of flower(側面). By the compounding method, the compound types mixed with the other patterns were used much more than the individual types composed by its own pattern. The flower patterns were used a lot in Jeogori(Jacket) regardless of the ganders and in men's Po(coat) including Cheollik(天翼), Dappo(胡), Jeonbok(戰服), Dahnryoung(團領), etc. Also contrary to these days, the flower patterned fabrics had come out in the shrouds. Judging from these facts, our ancestors wished that the meaning of the immortal life was included in the flower pattern.
