Relics, in which the most flower designs are seen in the late Joseon Dynasty were Chaekgeori (book rack painting). Looking into the history of Chaekgeori development, it was developed through four phases and, finally, into the Flower-arranged style due to the increasing importance of flower-arranged works than books themselves. In the early Chaekga-style Chaekgeori whose feature was realistic portrayal, the main trend was the inclined asymmetric triangle styles of flower works which had simple materials drawn on the elegant-colored vases making lines stand out. In the Book-Centered Chaekgeori, the leaves and the lines of the flower arrangement work became rich, and flowers got focused among materials as the concentration of materials became popular. In the Flower-arranged style Chaekgeori, there were seen triangular configurations of the vertical or the inclined styles getting out of the stereotype Chaekga-style Chaekgeori. Abundant materials were inserted massively, and one example, the configuration of Jayeonhwa 1 (Natural style, Rikka) could be seen in lotus works. In addition, there were the elements of painting and symbolic meanings found in the Flowerarranged style Chaekgeori, and there were also found voluminous vertical structures and even the features of modern flower arrangement. In the Seuphap style Chaekgeori (Amalgamation Chekulri) which embraces the wishes of ordinary people, there were lots of processed materials found such as the feathers of peacocks, Ganoderma (mushroom, Eternal youth grass), bizarre stones, and old trees, etc., and also found flowers containing auspicious meanings. It is believed that the colorful vases displayed on the Chaekgeori are not just a picture the results of the demand. Through the flower-arranged works of Chaekgeori loved by ordinary people, it is found that the flower culture was permeated into the real lives of people deeply in the late Joseon Dynasty.

두릅나무의 엽병을 1.0 mg/L 2,4-D가 포함된 MS 고체배지에서 배발생캘러스를 유도하였다. 배발생세포와 배발생세포괴는 1.0 mg/L 2.4-D가 포함된 MS 액체배지에서 배발생캘러스를 2주간 현탁배양하여 대량으로 얻었다. 그물망을 통과한 배발생세포는 1.0 mg/L 2.4-D가 포함된 MS 액체배지에서 배양하면 배발생능이 소실되지 않고 지속적으로 유지 및 증식시킬 수 있었다. 그물망을 통과하지 못한 배발생세포괴를 식물생장조절물질이 첨가되지 않은 1/2 MS 액체배지에 옮겨 2주간 배양하면 구상형의 체세포배로 발달하였다. 구상형의 체세포배는 5 L의 bioreactor를 이용하여 배양하면 심장형, 어뢰형, 자엽형의 배와 유식물체로 발달하였다. Bioreactor 배양을 통해 두릅나무의 체세포배를 효과적으로 대량증식 시킬 수 있었다. Embryogenic calli were induced from petioles of Aralia elata on MS solid medium supplemented with 1.0 mg/L 2,4-D. When embryogenic calli were transferred to MS liquid medium supplemented with 1.0 mg/L 2,4-D, embryogenic cells and embryogenic cell clusters were developed after 2 weeks of culture. Embryogenic cells were filtered through a 250 ${\mu}{\textrm}{m}$ sieve and the passed cells were proliferated and maintained in MS liquid medium supplemented with 1.0 mg/L 2,4-D. Embryogenic cell clusters entrapped on the sieve were transferred to 1/2 MS liquid medium without plant growth regulators, globular-shaped embryos were developed from embryogenic cell clusters after 2 weeks of culture. Numerous early stage somatic embryos could be developed to heart-shaped, torpedo-shaped, cotyledonary embryos and plantlets in 5 L bioreactor. Above results suggest that effective somatic embryo proliferation can be achieved via bioreactor culture systems in Aralia elata.
