'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.

We researched the physical, chemical, functional, textural, and manufacturing characteristics of yellow layer cake which prepared by adding different amounts of persimmon leaf powder (0, 4, 8, 12, 16%). The color of the crumbs inside the cake appeared dark, demonstrating that the L value decreased as the amount of persimmon leaf powder increased. The value of a, which corresponds to the level of redness, increased and the cake appeared dark red as the amount of persimmon leaf powder added increased; whereas, the yellowness of the cake tended to decrease as the value of b, which corresponds to the level of yellowness, gradually. As the amount of persimmon leaf powder added increased, the specific loaf volume of the cake increased, but the amount of baking loss tended to be similar at all. The textural characteristics of hardness and gumminess tended to increase, but cohesion and elasticity were not influenced by the addition of persimmon leaf powder. In the sensory test, color was rated low, but flavor, taste, and texture showed the highest score in 8% as the amount of persimmon leaf powder added increased. The general preference was highest when the persimmon leaf powder was added in the amount of 8%, and it decreased as the amount of persimmon leaf powder added increased.

Effects of application time And rate of chlorine on the chlorine absorption and distribution at different stalk positions of the plants were Investigated in burley tobacco grown under the pot condition. Treatment consisted of 6 application times (from 2 weeks before transplanting to 8 weeks after transplanting with 2 weeks' interval) and 2 application rates (2g and 4g-KCl/pot) by 6X2 factorial experimental design. The tobacco plants took up the chlorine rapidly just after chlorine application, and the chlorine content of leaf was increased proportionally to the rate of chlorine application. The chlorine was accumulated when much in lower leaves when chlorine was applied early, while the chlorine accumulated much in upper leaves when chlorine was applied late. The chlorine content of leaf was negatively correlated to the degree of brightness, red color and yellow color of cured leaf. Significant Increases In cured leaf ratio, leaf thickness, leaf weight and weight Per unit leaf area of harvested leaf were obtained with increased chlorine application. When the chlorine was applied early, the leaf weight showed Increasing tendency.

The purpose of this study was to investigate dyeing properties and antibacterial activities of cotton and silk fabrics treated with Ginkgo biloba leaf extracted with three kinds of aqueous solvents: distilled water, electrolytic reduction water and electrolytic oxidation water. The optimum dyeing condition of Ginkgo biloba leaf was 120 min at 8$0^{\circ}C$. Electrolytic reduction water had the highest dyeability to both cotton and silk compared with electrolytic oxidation water and distilled water. A color of extract by distilled water and electrolytic oxidation water showed yellowish Yellow Red, extract by electrolytic reduction water showed reddish Yellow Red. Irrespective of kinds of extraction solvents, appropriate acidity of medium was pH 9∼11 and pH 3 for cotton and silk fabrics, respectively. Colorfastness to laundering and Light fastness showed generally low but crocking fastness was excellent. Antibacterial activities of the treated fabrics above were 99.9%.

To study the dyeability(ΔE value) and color depth of silk fabrics dyed with Impatiens balsamina extracts. its flower, leaf and stem was extracted by water. This paper investigated some experiments under the various dyeing conditions such as dyeing temperature, dyeing time, repetition of dyeing, dyeing pH with silk fabrics dyed with Impatiens balsamina extracts. The results obtained were as follows 1. It was found that $\lambda_{max}$ of silk fabrics dyed with Impatiens balsamina extract was 260nm and its flower, leaf , stem and different colored flower(white, pint violet) had same $\lambda_{max}$ at 260nm. 2. $\Delta{E}$ values were increased when dyeing temperature, repetition of dyeing and time was higher, value of munsell of silk fabrics dyed with Impatiens balsamina extract was Yellow-Red. But dyeing temperature, repetition of dyeing and time was higher, shifted to longer wavelenth side. 3. Silk fabric dyed with Impatiens balsamina extracts at acidic pH was colored reddish Yellow-Red, alkali bath colored yellowish Yellow-Red in silk fabrics dyed with Impatiens balsamina extract.

We investigated the seasonal changes flower color of 163 deciduous woody landscape plants in the Suwon region from January 1, 1992 to March 20, 1993. The results were as follows; 1. By the month of anthesis of woody landscape plants, only one plant of Hamamelis japonica flowered in February, 15 species in March, 48 species in April, 63 species in May, 23 species in June, 12 species in July, and one plant of Hydrangea paniculata was flowered in August. 2. The flowering period was about 220 days from February 24, 1992 that Hamamelis japonica was anthesis to October 5, 1992 when Hydrangea paniculata was deblossomed. 3. By the flowering period of woody landscape plants, 81 species continued for 11 days through 20 days, and Rosa spp., 118 days, Hibiscus syriacus 'Yungkwang', 80 days, Largerstroemia indica, 65 days, and 6 species continued for 41 through 60 days, 10 species were 31 through 40 days, 43 species were 21 through 30 days, and 20 species were for less than 11 days. 4.

본 연구는 자주중산국수나무와 자주맥문동의 광도변화에 따른 생육 및 생리 특성과 엽색발현을 조사하여 적정 광도를 구명하고자 한 결과는 다음과 같다. 1.자주색 잎이 특징인 중산국수나무(Physocarpus opulifolius 'Diabolo')는 차광에 따른 생육 변화를 관찰한 결과 40% 차광구에서 생육이 좋았으나 양지조건일 때 생리활성이 2배 이상 좋은 것으로 나타났다. 엽색발현은 0% 차광구에서 85% 차광구로 갈수록 진한 자주색(RHS colour chart 202A, dark grayish red)에서 녹색(RHS colour chart 139A, dark yellowish green)으로 변화되어 본래의 품종 특성인 엽의 색이 사라져 관상가치면에서 저하된 것으로 사료되어진다. 2.자주맥문동(Ophiopogon planiscapus 'Nigrescens')은 노지상태인 무차광구에서 생육이 가장 양호하였고, 관상가치면에서 생육활성이 좋은 대조구에서 선명한 자주색이 잘 나타났으며 더욱 진해진 검붉은색(RHS colour chart 202A, dark grayish)으로 엽색이 발현되었다.
