A field experiment was conducted to find out the effects of field productivity, variety and nitrogen rate on the yield, quality, chemical constituents and physical properties of burley cured leaf in three field with different productivity(Degree of field productivity: A ; high, B ; medium, C : low) during successive two years(1988~89). The yield and quality were remarkably lowered when nitrogen fertilizer being applied much in low productive field. As compared with Burley 21, KB101 showed high yield, particularly the yield of KB101 in low productive field was relatively high. The effect of nitrogen rate on the yield was somewhat different according to field productivity and production year. When the nitrogen fertilizer being applied above 22.5kg/10a, the added nitrogen had no effect on the yield. Total nitrogen content of cured leaf grown in low productive field was high while total alkaloid was low, therefore total alkaloid/total nitrogen ratio was remarkably low. The lightness, red and yellow color of cured leaf grown in low productive field was remarkably low. As compared with Burley 21, the contents of total alkaloid and total nitrogen and shatter resistance index of cured leaf was somewhat low, while the filling power, lightness, red and yellow color were slightly high. Total nitrogen content of cured leaf was increased remarkably by nitrogen addition, but total alkaloid was not increased though the nitrogen fertilizer being applied above 22.5kg/10a. The filling power and shatter resistance index of cured leaf grown in high nitrogen plot, and the lightness and yellow color were low while the red color was relatively high. It comes into question that the visual quality being increased as well as increment of yield and nitrogenous compounds by nitrogen addition in high productive field. In low productive field, it is considerable that nitrogen addition for high yield should be prohibited because it causes the decrement of yield and quality, on the contrary.

Fifty accessions in Zoysia species and forty-one hybrid lines were evaluated in order to detect analyze the genectic variation of Zoysiagrasses and to obtain the basic information for breeding. 1.Plant height ranged from 13 to 34.5cm, leaf length from 7 to 26cm, leaf width from 2 to 7mm, and first leaf height from 1.1 to 8.5cm 2. The correlations among plant height, leaf length and first-leaf height were high, but leaf Width was correlated only With leaf length. 3. Stolon length was varied from 10 to 108cm, number of stolons from 12 to 53, internode length from 2 to 6.1cm and coverage percentage from 10 to 90%. 4.There were correlation among stolen length, number of stolons, internode length and coverage percentage except between stolen and internode length. 5.M1J and MC2 showed the highest level in stolen length, number of stolons and coverage percentage. Therefore they will be the best breeding materials for the purpose of fast covering. 6.According to the analysis on October 26, 1995, yellow color-change rate of leaves ranged from 5 to 85%, red color-change from 0 to 75% and sum of yellow and red change from 20 to 95%. Speciallty M2M1 and FL-41 kept green color untill early December, indicating that they had the late dormancy. 7. Visual assessment of stolon length and number of stolons, showed similar tendency With actually measured data. 8. Shoot density was very high in M2M1 and S2, and showed negative correlation with leaf width. 9. It is known in Korea that the darker green color of lawngrass is, the better it looks. There were 11 lines with dark green color leaves such as J 85-10, Meyer in Z. japonira, one asacession in Z. matrella and M2M1, M2S8, JM2, 55C2 in hybrid lines.

Dyeing behavior of indigo leaf powder was examined in regards to the effect of the amount of pigments on color and dye adsorption for silk dyed by reduction and nonreduction dyeing. The amount of indigotin and indirubin pigments adsorbed in dyed silk was examined by HPLC-DAD analysis. The color of dyed silk showed 7.7BG - 2.7B hue when silk was dyed at $50^{\circ}C$, and 3.5G - 4.9BG when dyed at $70^{\circ}C$. Blue ($b^*$) and green ($a^*$) color decreased as the pH of dyebath increased. When silk was dyed using nonreduction, R (red) and RP (red purple) hue and R hue was more apparent in samples dyed at $90^{\circ}C$. In reduction dyeing, amount of indigotin detected from silk exceeded the amount that was initially contained in the input dye. The amount of indirubin was lower than indirubin that was initially in the powder. In nonreduction dyeing, silk showed a higher amount of indirubin adsorption compared to silk dyed by reduction. The amount of indigotin adsorbed in silk was lower than the amount initially contained in the input dye. The amount of indigotin and indirubin adsorption was primarily dependent upon the dyeing method-reduction or nonreduction along with dyeing temperature and the pH of dyebath.

'춘풍적축면'은 '포자비적축면'과 '먹치마'를 교배 육성한 잎상추로 누운타원형 잎을 가진 축면 상추이다. 2000년 교배하여 2007년까지 계통육종법에 선발과 고정을 하였다. 전국 6개 지역(대관령, 경기, 충북, 전북, 경남, 제주)에서 2년간 봄, 여름, 가을 재배하였을 때 평균 2,069 kg/10a을 나타내어 기존 품종보다 주당 53매 정도의 잎을 수확할 수 있으며, 주당 무게는 평균 372 g으로 6% 수량성이 많은 품종이다. '춘풍적 축면'은 회색종자이며 누운타원형이다. 잎 상단부는 붉고 검으며 광택이 좋으며 잎 기부는 녹색으로 생육 모습은 초기에는 치마의 형태로 자라다가 후기에는 축면의 특성이 나타나는 치마와 축면의 중간형인 새로운 형태이다. 숙기는 정식 후 25일 후부터 수확이 가능한 중생종이며, 고온기 비가림하우스 재배시 적색이 늦게까지 유지되는 특성을 가지고 있다. 적색발현의 주 요인인 안토시안닌 함량은 17.5 mg/100g으로 기존 대조품종인 뚝섬적축면보다 3배 이상 많아 고온기 적색발현이 늦게까지 유지된다. 쓴맛 성분인 락투신(latucin+8-deoxylactucin+lactucopicrin)은 뚝섬적축면보다 적어 쓴맛이 적고 단맛이 나며 아삭아삭하여 맛이 좋다. 이것은 잎두께와 엽연이 뚝섬적축면보다 조밀하고, 잎의 경도가 19.8 kg/$cm^2$로 뚝섬적축면보다 강한 특성을 가지고 있기 때문이다. 이에 신품종 '춘풍적축면'은 봄작형에 적합한 품종이다.
