The Flavonoids of the bark Ectractives from Pinus koraiensis grown in Mt. Jiri were analysed. in this study. Dihydroquercetin(DHQ) was isolated from analysed diethyl ether soluble fraction in the EtOH(95%) extractives from the bark of Pinus koraiensis. 1) Diethyl ether soluble fraction content in the EtOH(95) extractive from the bark of Pinus koraiensis was 14.0%. 2) Development Standard of dihydroquercetin, H and I group among fraction of liquid chromatography were separated a section Rf value 0.4 by TLC. 3) The dried sample was tested by UV spectroscopy. Maximum peak of DHQ in methanol removed 289 nm to 292 nm in methanol mixed with 1N NaOH solution. It was identified to be phenolic compound having aromatic ring. Typical peak of monomer appeared at 1600 and 1800 cm. 4) R values in phenolic compound and hydroxyl appeared 3436 to 3200 cm and aromatic R value was at 1476 cm. It was identified to be phenolic compound having aromatic ring. Typical peak of monomer appeared at 1600 and 1800 cm. 5) The typical hydrogen bonding signal of DHQ by Proton NMR showed at 11.70 ppm between the OH-5 and 4-C=O. The H-6 and the H-8 on the A ring showed at 6.01 and 5.94 ppm, to be double doublet.

This paper was carried out to analyze the variation of composition of seed oil with storage periods. Difference of content of crude fat in fresh-cut seed and one year storage seed is not detected but in pentadecanoic acid, acid value, iodine value and peroxide value in one year storage seed have lower than those of the fresh-cut seed. Linoleic acid and oleic acid were high among of total fatty acid in fresh-cut seed but moiety of linolenic acid and icosanoic acid was low otherwise that of palmitic acid and oleic acid is increased in one year storge. In neutral lipid, capric and mytistic acid were high in fresh-cut, oleic acid, palmitic acid and linoleic acid were increased after one year storge. In glycolipid, the lauric acid and linoleic acid were high in fresh-cut seed, the palmitic acid was increased, otherwise, linolenic acid was decreased after one year storge. In phospholipid, palmitic acid and unknown part were high in fresh-cut seed, palmitic acid, oleic acid and linolenic acid were increased after one year storge.

This study was designed to find out an alternative to artificial pollination in kiwifruit production. The parthenocarpic kiwifruits induced by (N-2-chloro-4-pyridyl)-N-phenyl urea (CPPU) treatment tended to be less attractive due to deep furrowing and excessive outgrowth of stigma in mature fruits. Especially, on flower buds after CPPU spray, severe fruit-drop was induced. It was considered enough to spray CPPU at more than 4ppm to attain sufficient fruit set but needed to spray CPPU at more than 16ppm to attain marketable fruit size. When CPPU at 16ppm was sprayed to the same flower once, twice or three time, the fruits received CPPU treatment more time was larger but less attractive. Application of CPPU mare than at 16ppm seemed to be necessary to produce fruits heavier than 80 gr. Enlargement of the fruits received CPPU treatment mainly occurred cross wisely and vertical development was not affected and thickening of outer pericarp primarily contributed to the fruit enlargement. Difference in flesh color or contents of vitamin C and sugars between control fruits and CPPU-treated fruits was not noticed. In conclusion, CPPU treatment to induce parthenocarpic kiwifruits could be commercially applicable, only the method for improving fruit appearance is worked out.

靭皮纖維의 特性을 究明하기 위하여 닥나무, 뽕나무, 삼지닥나무, 산닥나무의 인피섬유에 대하여 形態 및 細胞壁 特性을 檢討한 結果는 다음과 같다. 樹皮率은 樹齡이 增加 될수록 감소되는傾向을 나타내고, 삼지닥나무와 산닥나무가 닥나무와 뽕나무 보다 높았다. 纖維長 및 纖維幅은 닥나무와 뽕나무가 삼지닥나무와 산닥나무보다 길고, 넓었다. 4樹種 靭皮纖維의 纖維長은 木村纖維보다 길고, 뽕나무科 靭皮纖維의 纖維폭은 針葉樹 假導管보다 작고 闊葉樹 木纖維와 비슷하며 팥꽃나무科 靭皮纖維는 假導管과 木纖維의 폭보다 작았다. 4樹種의 靭皮纖維는 纖維表面에서 壁孔이 確認되지 않았고, 2次壁이 존재하고 있는 것이 확인되었다. 靭皮纖維의 細胞壁은 木村纖維의 細胞壁과 다른 細胞壁이 두껍고 細胞內腔이 작은 細胞가 分布되어 있다. In order to evaluate characteristics of bast fiber, the types and the cell wall properties of various bast fibers originated from Broussonetia kazinoki Sieb. Morus alba var, romana Loddiges, Edzeworthia papyrifera Sieb. et Zucc. and Wikstroemia irichotoma makino. In the other hand, Broussonetia kazinoki Sieb. et Zucc. and Wikstroemia trichotoma Makino. The pits were not find in fiber surface of bast fibers from 4 species, but the presence of secondary wall was surely confirmed. The cell wall structure of bast fiber was a little different from that of wood fiber.
