多收性 및 葉菜用 들깨 品種育成을 위하여 國內 在來種들깨 40種을 蒐集供試하여 10個 形質에 대한 遺傳力 및 遺傳相關, 經路係數를 推定함으로서 效率的인 選拔을 위한 基礎資料를 얻고져 本 試驗을 實施하엿던 바 몇가지 結果를 얻었기에 이를 要約하면 다음과 같다. 1. 들깨의 10個 形質에서 有傳力은 成熟日數, 葉面積이 높았고 子房數, 節數 및 株當種實重等은 낮게 評價되었다. 2. 分枝數와 稈長 및 節數와 稈長은 正의 相關이 認定되었고, 1,000粒重과 花房數는 負의 遺傳相關이 認定되었다, 3. 遺傳力과 遺傳相關을 동시에 고려할때, 葉菜用들깨는 少節大粒種 系統의 選拔이 有望할 것이며 多收性으로는 花房數가 많고 長稈大粒種 系統을 選拔하는 것이 效率的이라 생각된다. 4. 各 形質이 收量에 미치는 直接效果는 化房數, 1,000粒重, 稈長의 順이였고 稈長은 直接效果보다 花房數, 1,000粒重 增加에 의한 間接的으로 收量에 影響을 미치는 것을 알 수 있었다. This study was conducted to obtain effective breeding information on high grain yield and high leaf yield of 40 native perilla varieties with genetic parameters; heritability, genotypic correlation and path coefficient. The results obtained were summarized as follow; 1. Heritabilities of characters involved in maturation period and leaf area among ten characters used were relatively higher than those of the other ones. On the other, the heritabilities of characters involved in number of ovary, number of branches and grain yield per plant were relatively lower that those of the other ones. 2. There were positive genotypic correlations between number of branches and culm height., and between number of nodes and culm height. On the contrary, a negative correlation betwen two characters of 1000 grain weight and number of flower clusters was shown. 3. As results of heritability and genotypic correlation analyses, it was recommended that for high grain yield of perilla plant type with characters of relatively less nodes and larger seeds should be selected. Also it was thought that for vegetable perilla, the plant type with relatively more flower clusters, longer culm height and larger seeds should be selscted. 4. According to analysis of path coefficent, direct effect values of characters involved in flower cluster number, 1000 grain weight and culm height on the grain yield per plant lowered in the other mentioned above, showing that the effect of the culm height had indirect influence on the yield by increases of flower cluster number and 1000 grain weight.

To ellucidate immunologic activities of ginseng saponin, the splenic leukocytes of BALB/c mice were incubated in RPMI medium for 48hr with or without ginseng total saponin(GTS), and then analyzed flow cytometrically. Upto the concentration of 100㎍/㎖, GTS exherted stimulatory effect on the immune cells most prominently on B cells: the percentage of the surface Immunoglobulin (sIg) -positive cells (B cells) of the control was 47.l%, while that of GTS treated was 58.9%. The percentages of monoclonal antibody(mAb) J1j-reactive cells (T cells) were 28.8% and 3l.3%, those of mAb Gkl.5-reactive cells (CD4' T cells) were l8.5% and l9.l%, and those of mAb M1/70-reactive cells (mostly macrophages) were 4.4 and 5.0% at the concentration of 0 and 100㎍/㎖, respectively. However, at the concentration of 300㎍/㎖ or higher, GTS was found to be toxic to the immune cells especially to B cells in that the flow rate of the cells (gated viable cells) significantly decreased and the percentage of B cells droped from 58.9% to 31.2% and 25.4% at l00, 300, and 1000㎍/㎖, respectivelly. These data strongly suggests that GTS would exhert B-cell mitogen-like activity at physiological concentrations of 100㎍/㎖ or lower.
