Two and three years old branches of a paulownia tree were respectively collected on January and April, and the aqueous extract from the branches was then treated to four tested crops, Chinese cabbage, leaf mustard, tomato and rice, in order to find the allelopathic effects by different concentration of the extracts. Generally, there were allelopathic effects of the aqueous extracts on the tested crops with increment of concentration and regardless of brance ages and or collecting season. The results were summarized as follows. Germination rate of Chinese cabbage and rice were lower with treatment of the extracts from the branches which were collected on January. Otherwise, leaf mustard and tomato showed lower value with the extract which were collected on April. Germination time and average germination period of Chinese cabbage and tomato were delayed with treatment of the extracts from the branches collected on April, and the corresponding value of rice and leaf mustard showed the opposite results. State of germination of Chinese cabbage was low with treatment of the extract on January, and it was high on April although the germination period was delayed. In case of rice, it was high without regard to the concentration of extracts.

This study was undertaken to investigated the damage of the crops by the migratory birds at the area of the Nakdong river-mouth, Pusan, which were designated as a natural monument (No. 179) for the habitat of the migratory birds. The study plots were respectively selected at 3 places in the upstream of the mouth, Dajeo 1 Dong, Daejeo 2 Dong, Samrak-Dong and at 3 places in the downstream, Myungji-Dong, Jangja-Do, Elusuk-Do. The crops cultivated in the study plots were divided into 2 groups : spring sowed crops-Chinese cabbage, carrot, radish, Swiss chard and fall sowed crops-barley, wheat, rape, spinach. The status of crop damage by the birds and the results of the survey from the farmers are summarising as follow : 1) Except the plots in the upstream and Jangja-Do, the values of the crop cover were all 5 and there were no damage on the spring sowed crops by the migratory birds. 2) There were no significant differences in the leaf and root growth between the cheesecloth treatment and the crops. However, in the case of carrot, there were significant differences in the leaf length, width and mass and was tend to heavy in the root mass. 3) The dry mass was different in leaves and roots among the spring sowed crops due to the moisture content. The moisture content of leaves was high in Chinese cabbage and low in carrot, and the content of roots was high in carrot and low in Swiss chard. 4) There were no significant damage on the fall sowed crops in the upstream plots and Myungji-dong in the downstream plots, which the values of the crop cover were 5 respectively. In the Jangja-Do plot, the corresponding values were all 0, and the values int he Eulsuk-Do were 2.00 (wheat) and 2.33 (rape and spinach) respectively. 5) In the Jangja-Do plot, the growth of the fall sowed crops was impossible because the seeds and germinated plants were fed by the migratory birds soon after the seeding. 6) The differences of harvesting mass were significant in all the fall sowed crops. There were also significant differences in leaf width of barley, height of wheat and root mass of rape. 7) There were significant differences in the moisture content between the crops and plots(e.g.. the dry mass was different in the leave and root of spinach and in the root of rape). 8) The dry mass of the crops tended to heavier in the downstream plots than in the upstream plots. 9) In the habitat of the migratory birds, the mouth of the Nakdong river, there were various spring sowed cultivar; lettuce(46 households), garland chrysanthemum (29) and Chinese cabbage (27). A few fall sowed cultivar were cultivated; spinach, Chinese cabbage and spring onion. 10) On the survey of the experience in the crop damage by the birds, 93 households had the experience and 25 had no experience. The damaging rate were varied : 33 households were less than 10% and 29 were more than 50%. 11) According to the survey, 62 households covered the cultivated fields with nets or plastic materials and 36 leaved the fields as that were. 12) Eighty eight percent of the survey answerers answered that the number of the migratory birds were decreasing every year. About 70% of the answerers thought that the environmental pollution is a main cause for the decreasing number of the birds. 13) The answerers replied that the cultivated land should be leaved as it is (39%) and developed as the garden city(39%). In the issue of the habitat for the birds, 50% of answerers were agreed to the closing down of the habitat and the rest of them were disagreed to that.

쑥의 水容性 抽出液에 의한 相互對立抑制作用의 效果

河祥永 東亞大學校 大學院 1994 大學院論文集 Vol.19 No.-

This study was undertaken to estimate the growing propensity of nine crops, Chinese cabbage, Radish, Leafmustard, Garland chrysanthemum, Lettuce, Whorled mallow, Tomato, Cucumber and Carrot, according to the different treatments of mugwort(Artemisia primceps). It was carried out two experiments, the seed germination test and the growth test, during the studying period. The seed germinationtest was determined by using the water soluble extracts of mugwort foliage and rhizome. The extracts were adjusted and then treated to the crops as concentration of 25, 50, 75 and 100%. Another experiment, the growing test was performed by using the mugwort powder, which was dried in the shade, and then bed soils were mixed with the mugwort powder at the weight of 3, 6, 9 and 12g respectively. The following is the results of the aforementioned experiments. With the treatments of mugwort foliage extracts, the seed germination rate was higher in 6 crops, except Lettuce, Tomato and Cucumber, With the extracts of mugwort rhizome, it was higher in Leaf-mustard, Garland chrysanthemum and Tomato than in other crops. In the germination speed with the treatments of mugwort foliage, it was higher in seven crops, except Cucumber and Lettuce. With the mugwort rhizome, it was lower in Leafmustard, Tomato and Carrot than in other crops. The average germination time of all the crops was longer in the treatment with the foliage extracts than in the control treatment with no addition. In the treatment with the rhizome extracts, it was longer in Tomato and Carrot than in the control. In the starting day of emergence, all the crops took longer time in the treatment with foliage extracts than in the contril. In the treatment with the rhizome extracts, it was longer in Garland chrysanthemum, Tomato and Carrot than in the rhizome extracts, it was longer in Garland chrysanthemum, Tomato and Carrot than in the control. With the rhizome extracts, it was significant in Radish, Leafmustard, Tomato and Carrot. In the termination time of germination, there were inhibition effects in Chinese cabbage, Lettuce, Tomato, Cucumber and Carrot due to the treatment of foliage extracts. With the rhizome extracts, inhibition effects were appeared in Radish, Tomato and Carrot. Summing up all the aforementioned results, the water soluble extracts of mugwort foliage had higher inhibition effects in the crops than the rhizome extracts. With different treatments of mugwort powder, the correlation between leaf length and width was positive. Furthermore, most of all the correlation coefficients were approximately 1 ; that is, the correlation between leaf length and width had a perfect relation. The plant height was decreased because of increasing the amount of powder without regard to the crop species. In the percentage of dry matter of leaf, it was higher in Whorled mallow, Cucumber and Carrot. In the percentage of dry matter of root, it was higher in Chinese cabbage and Radish, although varied in some crops because of increasing the amount of mugwort powder.
