This study was conducted to investigate and compare some seed characteristics of round-seeded spinach cultivars and to find out the effect of cultivars, seed sizes, temperature, moisture level and light on the germination. Seed characteristics, such as seed size distribution, seed compactness (seed wt/volume), seed weight including the weights of true seed and pericarp, differed considerably depending upon cultivars. Those seed produced in Europe or in U.S.A. exhibited heavier seed weigh, larger seed size, and high seed compactness value. Smaller seeds showed better seed germination rate especially at earlier stages at 18℃. At lower temperatures, seed germination was markedly delayed and the duration from the beginning to the termination of seed germination was greatly extended. Larger seeds germinated faster than smaller seeds at low temperatures, but smaller ones germinated faster than larger ones at high temperature(above 18℃). Final seed germination rate was low at high temperature especially in small seeds. Excess water significantly reduced the germination rate, especially of the larger seeds.

The authors studies the effects of Nicotine on the Body weight growth of the developmental chick embryo. On the sixth day of incubation, 0.41mg, 0.82mg and 1.65mg of Nicotine were injected into the chorioallantoic sac of each egg of three groups and one group was injected physiological saline solution as a control, and the eggs were broken for weighting the body weight in every other day from the twelfth day to eighteenth day of incubation. In an attempt to analyze the growth of the body weights, growth formula of Zimmerman and relative growth formula of Huxley were applied. The following results were obtained. 1. The growth of chick embryo boby weight was affected as inhibiting by the Nicotine. The inhibiting effects were in proportion to the injected Nicotine dosage. 2. The growth quantity of the body weight injected 1.65mg was almost half weight of the control group body weight. 3. Growth rate was decreased continuously with tine until 18th day in the 1.65mg injected group but it was increased in 0.41mg and 0.82mg injected group with time lapse from 12th day to 18th day, and 0.41mg injected group was more increased than 0.82mg injected group. 4. Specific growth rate decreased in the all of 0.41mg, 0.82mg and 1.65mg injected group and in the decrease degree 1.65mg and 0.82mg injected group ware severe and 0.41mg injected group was slight. 5. Growth centers of growth gradient were 12th day in the 0.41mg injected group and 18th day in the 0.82mg and 1.65mg injected groups. 6. Relative growth rate was also decreased proportionally in related with injected Nicotine dosage.

버섯 균사체의 심부배양에 의한 버섯향료 생산을 위한 우수 균주의 선별

변태강 建陽大學校 1999 建陽論叢 Vol.- No.7

Recently, there is a tendency to replace synthetic flavors by natural ones. This trend can be ascribed to increasing health and nutrition conscious life-styles. The term 'natural flavor' includes enzymic and fermentative processes. Edible mushrooms are known for their unique and subtle flavor characteristics and have wide application as a food flavoring additive in the production of soups, sauces and instant products. 1-octen-3-ol is the main chemical responsible for the mushroom flavor. Submerged culture of mushroom mycelium is a faster and more easily controllable method than the established growth of fruiting bodies by solid-state fermentation. Although a number of mushrooms give good yields of mycelium biomass in submerged culture, a satisfactory flavor has been found in only a few cases. Among the nine strains tested, Agaricus bisporus 705 showed the greatest production of mushroom flavor.

The number and distribution of the retinal ganglion cells in the 1-week-old and 7-week-old ducks were determined from whole flat mounted preparations stained with methylene blue and thionin. The results were summarized as follows. 1. In the 1-week-old and 7-week-old ducks, the areas of the retinas were 269.4㎟ and 357.2㎟, respectively, and the total cell numbers 1,742,800 and 1,808,800, respectively. 2. The ganglion cells based upon soma diameter were classified into 3 groups such as small (below 10㎛), medium (10-20㎛) and large (above 20㎛) ganglion cells. In 1-week-old duck, the relative frequencies of these 3 groups were 91.0%, 8.5% and 0.5%, respectively, and in 7-week-old duck, 83.7% 14.7% and 1.6%, respectively. 3. Area centralis was located at the distance of 1.6mm (1-week-old) and 2.0mm(7-week-old) nasal side from the anterior tip of the pecten. The number of ganglion cells in the area centralis was 11,000 cells/㎟ (1-week-old) and 12,000 cells/㎟ (7-week-old). 4. There was a gradual decrease in density of retinal ganglion cells extending from area centralis to the periphery of retina. 5. The density of the large (above 20㎛) ganglion cells was higher in the peripheral regions than in the center of retina. Higher densities were noted in the superior-temporal region in 7-week-old duck, and in the nasal region in 1-week-old duck than in the other regions. 6. The direction of the beak tip is approximately 30° in 1-week-old and 26° in 7-week-old duck from the angle of the pecten.

In order to set the distribution pattern and surface area of the mucosal epithelium and submucosal gland in the mice nasal septum. 3-month-old healthy 6 mice weighing 25gm approximately have been contributed for this research. For the mapping of the each nasal epithelium and submucosal gland in the submicroscopic level, the routine paraffin block of the mice nasal septum were cut as the 10㎛ thick at 110㎛ intervals. Consecutive 2 slides were stained with H-E and PAS and reconstructed in form of maps representing the structure in a sagittal plane. The results obtained from this research were summarized as follows. 1. The unilateral nasal surface epithelial area of the mice nasal cavity was 31.23㎟ 2. The areas of the stratified squamous epithelium, respiratory epithelium and olfactory epithelium which compose the unilateral nasal epithelium were 4.47㎟(14.3%), 12.7㎟(40.8%), and 14.02㎟(44.9%), respectively. 3. Submucosal glands in the mice nasal septum were divided into the PAS-positive, PAS-negative and Bowman's glands by the PAS staining. 4. The surface area of the PAS-positive glands in the nasal unilateral septum was 5.23㎟ which is located in the central area of the respiratory portion. 5. The surface area of the PAS-negative glands in the nasal unilateral septum was 5.05㎟ which is located above and below the PAS-positive gland. 6. The surface area of the Bowman's glands was 12.1 ㎟ which was located in the olfactory region. 7. In the vestibular region., 3 ducts of PAS-negative glands of the respiratory region are found, and below the nasal septum there is the infraseptal gland(PAS-negative).
