In this study, the chemical constituents of bulb from Lilium lancifolium and Lilium tsingtauense were investigated. The content of moisture, crude protein and fiber of bulb from L. tsingtauense was higher than that of L. lancifolium, whereas the content of crude ash and nitrogen free extract of bulb from L. lancifolium was higher than that of L. tsingtauense. HPLC analysis revealed that total free sugar and amino acid content of bulb from L. tsingtauense was higher than that of L. lancifolium. There was no remarkable difference in proximate composition between the two species. The content of p-coumaric acid and ferulic acid was 1.93 mg% and 0.25 mg% in ethyl acetate fraction of L. lancifolium, on the other hand, 2.94 mg% and 0.46 mg% in ether fraction of L. tsingtauense. These results suggest that the bulb of L. tsingtauense can be considered as promising oriental medicine resource likewise L. lancifolium.

A suitable bioreactor culture system for shoot proliferation and bulblet formation of Allium victorialis var. platyphyllum Makino was established. Uptake of soluble carbohydrates in different bioreactor culture systems was also analyzed during the entire culture period. Optimal conditions for multiple shoot formation were determined in raft culture (RC) and modified raft culture system (MRC) (13-15 per explant) in which the explants were placed on a net contacting liquid medium. For bulblet formation and enlargement, 93.4％ of shoot clumps formed bulblets at the basal part. Furthermore, they were uniform in size when cultured with ebb & flood system (E&FS). Bulblets harvested from RC and MRC showed vigorous rooting, however, their growth was not uniform. Whereas soluble carbohydrate contents in the bulblets cultured in E&FS were low, starch content was high. Sucrose, glucose and fructose concentrations in the medium of E&FS culture system decreased as bulblet formation and enlargement proceeded, suggesting that external sucrose is taken up to by the cells before it is hydrolyzed.

The effect of abscisic acid (ABA) and methyl jasmonate (MeJA) on bulblet formation from the culture of Allium victorialis var. platyphyllum Makino was studied. Shoot clumps were cultured on MS medium containing ABA (0, 0.01∼2.0mg/L) and MeJA (0.01∼5.0mg/L). ABA at low concentrations (0.01mg/L) induced shoot proliferation without bulblet formation. However, bulblet formation started on the medium containing MeJA approximately in 4-6 weeks of culture. Furthermore, 1.0mg/L MeJA resulted in bulblet formation at high frequency (100％) as compare to the control (46.1％). Cortical cells of the bulblets enlarged on medium with MeJA had dense protein-like substance in expanded and round cells when examined under the microscope. The data described here show that formation and enlargement of bulblets from Allium victorialis can be improved by addition of appropriate concentration of MeJA.

This study was conducted in order to know the ecology and to establish the control method of Potamogeton distinctus A. BENN. The tubers of Bog pond weed was almostly located at soil depth of 10 cm to 20cm, germination rates and number of formed tubers were different according to transplanting depth of soil. Effects of herbicides application on weeds were different according to leaf-stage of pondweed, and the pondweed were withered to death by absorption of Avirosan into the leaves. It was suitable to keep water depth at 3cm level until about a week after Avirosan application.

At Otani University in Kyoto, Japan, there is a rubbed copy of Tripitaka Koreana, presumably printed in 1381. According to the postscript of the copy, written by Saek Lee himself, the rubbed copy was made at Haeinsa temple in 1381 and was kept at Sinluksa temple in Yeuju. The copy was delivered as a gift to Japan in 1414 and now is kept at the Library of Otani University. Although an approximate summary of the content of the copy was reported in the early 2000s after a basic survey, details of the copy, including the concrete format and packaging paper, are not known yet. In this paper a detailed survey of the copy is conducted on the 109 pages. The copy is divided into two parts: the wrapping and the inner pages. The wrapping paper is divided into yellow and brown colors depending on the material of the paper. The yellow colorwrapping paper was possibly made in 1381 at the time of the rubbed printing, and the brown wrapping paper was repaired after being moved to Japan. Using funds collected in February 1380, the copy of Gyeong(經), Yul(律), and Ron(論) chapters was printed in April 1381. Binding of the copy was completed in September, and the wrapping paper with the title in gold was made in October 1380. The box for keeping Buddhist scriptures was manufactured in November 1380. The copy was moved to Sinluksa temple in April 1382 and delivered to Japan in 1414. At Otani University, the copy is stored in separate rectangular boxes 32.1×25.3cm in size with a height of 23.6cm. The rectangular plate on the four sides is red in external color but black colorinside. The box for keeping Buddhist scriptures was probably made in 1381, but a partial repair was made later. Because of the difficulty of executing a detailed survey of the box for Buddhist scriptures, it is hard to find out its nation and period of production. We look forward to studying the copy as well as the box for Buddhist scriptures in future.

This study was performed to investigate the role of plant growth substances on the bulbing of cold type of garlic (Allium sativum L. cv. Uiseongmaneul) during long and short day conditions. The change in endogenous plant hormones such as abscisic acid (ABA), jasmonic acid (JA) and sugar contents in leaf blade and sheath was examined during the growth stage from bulb differentiation (starting at April 16) to bulbing (April 24 to May 18) in cold type of garlic. In the long day condition, ABA contents were higher than short day condition and ABA contents of leaf sheath were higher than leaf blade. ABA contents of growth stage in garlic were not changed during growth stage from April 16 to May 2, however it rapidly increased during bulbing (May 2 to May 18). On the other hand, endogenous JA contents in short day condition did not change in long day condition, it increased from April 16 to May 2. JA contents in the leaf sheath (33.85-62.04 $ng{\cdot}g^{-1}$ DW) were higher than leaf blade (15.39-30.04 $ng{\cdot}g^{-1}$ DW). These results showed that garlic bulb differentiation and bulbing was induced by JA in leaf sheath. In long day condition, total sugar contents in the leaf blade were increased from bulb differentiation (April 16) to bulbing (May 4) and it was decreased during bulbing (May 4 to May 18) while the total sugar content in leaf sheath were gradually increased from bulb differentiation (April 16) to bulbing (May 18). In conclusion, our results showed that there is a significant correlation between the bulb development of garlic and hormonal content in the leaf sheath.

The most troublesome perennials in the paddy fields in Korea, such as Cyperus serotinus, Potamogeton Franchetii, Sagittaria pygmaea and Eleocharis Kuroguwai, were studied about shape, aspects of ,germination, depth of development(under flooded and upland conditions), reproduction process and production amount. And these characters were compared with in these perennials.

Apical meristems tissue were cultured on LS medium with different zeatin and NAA concentrations to compare their potential to regenerate shoots, roots and bulblet formation. Shoot regeneration from apical meristem was effective on LS medium added with zeatin 0.1, 0.5, 1.0 mg/L alone treatment or zeatin 0.5 mg/L and NAA 1.0 mg/L combination treatment. A high frequency of root regeneration was obtained on LS medium supplemented with zeatin 0.5 mg/ and NAA 1.0 combination treatment. Linsmaier and Skoog(LS) medium with NAA 3.0 mg/L and zeatin 1.0 mg/L combination treatment gave the best results for normal bulblet formation#KW=Allium wakegi ; plant regeneration ; bulblet formation

The structure of amyloplasts and intercellular transport in the old and new bulbs of Frjtillaria pallidiflora were observed by means of electron microscope. The structure of internal membrane system was different between new and old amyloplasts. The active intercellular transport was observed in both new and old bulbs. The phenomena of encytosis and exocytosis always could be found in the cell membrane, and plasmodesmata established a symplasmic pathway for intercellular transport. Groups of vesicles often located at the ends of plasmodesmata, showing that they participated in the intercellular transport. These results laid a foundation for the further study on the mechanism of growth and development in Fritillaria pallidiflora.
