본 연구는 마의 지상부에서 형성되는 주아를 이용하여 이듬해 종서로 사용 가능한 씨마 생산을 위한 주아 재배법을 개발하기 위하여 수행하였으며, 파종기, 파종량, 파종주아 크기에 따른 씨마 수량을 검토하였다. 1. 주아 파종기가 늦어질수록 생장 일수가 짧아져 괴경장이 짧아지고 평균 괴경중이 가벼워지는 등 괴경의 크기가 작아졌다. 5월 11일 파종의 경우 씨마용으로 사용할 수 없는 무게가 20g 이하 되는 괴경수가 많아짐으로 파종은 늦어도 5월 1일까지 이루어져야 할 것으로 판단된다. 2. 파종량이 많을수록 괴경장이 짧아지고 평균 괴경중이 가벼워지는 등 괴경의 크기가 작아지므로 마로 사용 가능한 $21{\sim}4kg$ 크기의 괴경수를 고려할 때 200kg/10a가 파종 적량으로 판단되었다. 3. 파종주아의 크기가 클수록 출아율과 평균 괴경중이 높아져 단위 면적당 괴경 수량이 높게 나타났다.

Seed 중합 방법에 의하여 단분산성 다공의 폴리아크릴로니트릴-에틸렌글리콜 디메타크릴레이트 (PAN) 고분자 마이크로 겔이 제조되었다. PAN 마이크로 겔의 물리적인 특성을 모노머/seed와 희석제/모노머의 비율, 가교제의 농도 및 희석제의 종류에 따라 연구하였다. PAN 마이크로 겔의 입도 분포는 모노머/seed의 비율이 50 이하 일 때 단분산성을 나타냈으며, 가교제의 농도가 증가할수록 입자 내부의 미소 구체 (microsphere)의 크기가 작아져 더욱 밀집된 형태를 나타내기 때문에 입자의 비표면적이 증대되었다. 또한 희석제로 톨루엔을 사용하고 희석제/모노머의 비율이 1.0일 때 입자표면의 세공이 가장 발달되었다.

Korean cultivars of buckwheat(Fagopyrum esculentum Moench.) was crossed with Canadian cultivars in order to improve seed yield as well as leaf production of buckwheat for using as food and medicine. The agronomic characteristics and rutin contents of F$_2$ hybrids are investigated for further selection of superior lines. Dry weight per plant was the highest in a line 1110(6.71g) and leaf weight per plant was the highest in a line 1110(1.91g). Hybrid seeds were 0.55 - 0.70cm long and 0.37 - 0.47cm wide on average. 100 seeds weight ranged from 2.57g to 3.58g. Line 1076 produced the longest seeds(0.70cm) and line 1186 was the longest in seed width. Line 1196 showed the highest 100 seeds weight(3.58g). The highest frequency of the LWR(length/width rate) was 0.66~0.70, indicating that seed shape of the hybrids was mostly oval. Line 1087 showed the highest contents of rutin(77.26ppm). Lines 1090 and 1181 contained respectively rutin of 54.76ppm and 54.35ppm in the seeds. From the yield and rutin point of view, the most superior lines was line 1087 among the lines used for this study.

For better understanding of population dynamics of Symplocarpus renifolius, some aspects of seed production were studied in natural populations for 3 years. The rate of reproducing plants (RP) was 8.06% among the whole studied. The RPs were 0.0% in leaf size class under 500cm2 per individual, and 3.6% in 500~1,000cm2, and 44.3% in over 3,000cm2. The resource allocated to sexual organ was 11.6% of total biomass at the end of growing season, and that to belowground was about 80% regradless of presence or absence of sexual organ. In the previous and the next years of seed production, the energy allocated to sexual organ didn't affect the changes of leaf size, year by year. After flowing season. Especially, a large number of sex organ were degraded in April, a period of pollination and fertilization. The number of seeds per individual was degraded in April, a period of pollination and fertilization. The number of seeds per individual was 13~22 and didn't relate to leaf size. But the weight per seed increased along leaf size per individual. Therefore, in S.renifolius population, large individual produced large seeds rather than many seeds.

E. japonica is a well-known medicinal plant in Japan. The leaves of E. japonica were reported to have a hypoglycemic action. However, seeds of E. japonica are discarded and not used. To elucidate for anti-diabetic effects of E. japonica, Type 2 diabetic mice were allocated to control group, E. japonica leaf, and seed extract group. Animals were fed a 2018S Teklad global 18% protein rodent diet. Animals were received daily oral injections of E. japonica leaf or seed extract at a dose of 200 mg/kg body weight for 6 weeks. Body weight, food intake and water intake, and total adipose tissue weight of animals were significantly reduced by feeding of E. japonica leaf extract. All E. japonica extract groups significantly decreased fasting blood glucose, glycosylated hemoglobin levels, size of adipocytes and serum adiponectins. However, they did not have a beneficial effect on the serum triglyceride and cholesterol in the diabetic animals. These results suggest that E. japonica seed and leaf extracts have a antidiabetic effect by controlling of blood glucose and decrease of size of adipocytes in db/db mice and seed extract is more effective in hypoglycemic action than leaf extract.

Extraction of oil from Moringa oleifera seed using Response Surface Methodology (RSM) was investigated. Effects of three factors namely: sample mass, particle size and extraction time on the response, Moringa oleifera a volume extracted, were determined. The Box-Behnken design of RSM was employed which resulted in 15 experimental runs. Extraction was carried out in a 250 ml Soxhlet extractor with Hexane and Ethanol as solvent. The Moringa oleifera seed powder was packed inside a muslin cloth placed in a thimble of the Soxhlet extractor. The extraction was carried out at 60℃ using thermostatic heating mantle. The solvent in the extracted oil was evaporated and the resulting oil further dried to constant weight in the oven. This study demonstrates that Moringa oleifera oil can be extracted from its seed using ethanol and acetone as extraction solvent. The optimum process variables for both solvent (ethanol and acetone) was determined at sample weight of 40 g, particle size of 325 ㎛ and extraction time of 8 hours. It can be deduced that using acetone as solvent produces a higher yield of oil at the same optimum variable conditions compared to when ethanol was used.

Ultra-drying [＜5.0% seed moisture content (SMC)] storage technique is a cost-effective storage method for oily seeds. To decide proper ultra-drying condition for soybean seeds, drying rate was compared three silica gel to seed ratios, two seed sizes with varietal difference, two kinds of container, and three seed amounts per container under :t 23$\pm$1$^{\circ}C$. When the relative humidity (RH) was reduced at the rate of less than 0.1 % a day, silica gel was replaced with dry one by 47 days. Higher silica gel to seed ratios (3:1 and 2:1) dried faster than lower ratio (1:1) until 28 days, but not after 43 days of drying. Also, large seeded variety was dried faster than small seeded variety. Kinds of container and seed amounts per container didn't show differences in drying of soybean seeds. After completion of ultra-drying, percentage germination by standard germination test (SGT) was not different among silica gel to seed ratios, kinds of container, and seed amounts per container, except among seed sizes (varieties). Before SGT, soybean seeds were premoistened using saturated ${CaCl}_2$ for 48 hours and ${NH}_4$Cl for 24 hours in desiccators. To compare germinability between ordinary-dried seeds and ultra-dried seeds, the seeds of seven soybean varieties, which were varying in size from 8.1 to 34.9 g per 100 seeds, were dried using same amount of silica gel under 23$\pm$1$^{\circ}C$. After completion of 76 days of drying, SMCs were reduced to 3.13-3.45% from 7.86-8.82%. SMC after completion of drying was not correlated with 100-seed weight (r=0.556). Before germination tests, soybean seeds were premoistened using saturated salt solutions. Percentage germination was higher with ultra-dried seeds than ordinary-dried seeds in SGT and higher with ordinary-dried seeds than ultra-dried seeds in AAT at the beginning of storage and after 6 months storage, but general trend of percentage germination was not observed among varieties classified by 100-seed weight. From these results, we concluded that further studies are needed to improve ultra-drying storage method for soybean seeds.

Umbelliferae medicinal crops have low germination under natural condition. Special objective of this study is to investigate morphological characteristics of seeds and effects of environmental factors such as light and temperature on their germination and seedling growth in Umbelliferae plants, using them as oriental medicine materials. Fruits of Umbelliferae are bi-partite type and form 2 seeds. Their oil canals and funiculus or carpaphore has apparently specific shape. Seed shape of Buplerum falcatum, Ligusticum acutilobum and Foeniculum vulgare are oblong, Ledeboutiella seseloides, Angelica dahurica, Angelica gigas elliptic, and Ostericum koreanum ovate. Color of seed coats varied from yellow to dark brown. Seed size was 3.2 to 6.9 mm in length, 1.7 to 4.9 mm in width. One thousand-seed weight of Buplerum falcatum was lowest(at 1,660 mg) and Ledebouriella seseloides and Angelica gigas were relatively highest(at 3,970 mg) having larger size than any others. Optimum temperatures for seed germination and seedling growth ranged from 20 to $25^{\circ}C$ and especially temperature at $25^{\circ}C$ improved seed germinations of Ledebouriella seseloides, Angelica dahurica and Ligusticum acutilobum regardless of light condition.
