朴道秉 진주농과대학 1970 진주농과대학 연구논문집 Vol.- No.9

Vinyl주머니 被覆法 및 Vinyl tunnel法이 在來式인 切接後 盛土法에 代替될 수 있는가를 알고자 本實驗을 하였다. 1. Vinyl주머니 被覆法은 95.5%, Vinyl tunnel 被覆法은 91.1%로 高率의 活着環을 보였고 Vinyl結縛盛土法은 84.4%, 짚 結縛盛土法은 77.7%의 活着率을 보였다. 2. 根頭接에는 Vinyl주머니 被覆法과 Vinyl tunnel法이 다 좋으나, 高接에는 Vinyl주머니 被覆法이 作業이 簡便하고 接穗 採取 貯藏에 制限이 적고 接의 有效時期가 길어 便利하므로 이 法은 利用할 價値가 있다고 생각된다. 3. 小形 Vinyl주머니 (直徑 4.45cm, 길이 20cm)속의 溫度는 外溫보다 若干(0~4˚) 높고 또 袋內의 濕氣는 近飽和狀態이어서 活着率을 높임에 有利한 것 같다. 4. Vinyl주머니 被覆法은 遮光하지 않아도 너무 高溫이 되지않고 5월5일에 當日 採取하여 잎을 除去한 接穗도 活着率(84.4%)이 높으므로 이 方法은 接의 可能時期가 매우 넓어 便利하다. These experiments were carried to discern whether the former method of soil covering after cut-grafting can be replaced by the methods of vinyl bag covering and vinyl tunnel covering. 1. percentages of union by callusing are as follows;95.5% in case of vinyl bag covering, 91.1% in vinyl tunnel covering, 84.4% in soil covering after tying with vinyl, and 77.7% in soil covering after tying with straw. 2. In crow-grafting, both vinyl bag covering and vinyl tunnel covering were satisfactory, but in top-grafting, vinyl bag covering was convenient when working, easy for collecting and preserving of scions, and the limited time of grafting was long. Therefore this method, I think, it very suitable for adopting. 3. The temperature in the small vinyl bag(diameter 4.45cm, length 20cm) is somewhat(0-4℃) higher than the atmospheric temperature and the moisture in the vinyl bag was near saturated condition, so this method is recommendable to increase the rate of graft-union. 4. The temperature in the vinyl bag was not so high, even though not adopting the shade method, and the scions, which were collected on 5th of May and taken off the leaves, were high in union percentage(84.2%), accordingly in this method the available period of grafting is very long.

葡萄 Campbell Early의 結實에 미치는 Gibberellin의 影響

朴道秉 진주농과대학 1962 진주농과대학 연구논문집 Vol.- No.1

葡萄 Campbell Early에 開花 8日前 開花 10日後 各 1回씩 100ppm의 Gibb을 處理하였던 바 다음과 같은 結果를 얻었다. 1. 約 40日間 熟期가 빨라졌다. 2. 花 가 枯死하고 果房이 畸形이 된 것이 많았으며 따라서 收量은 半減되었다. 3. 無核果는 若干 造成되었으나 實用的 價値가 없었다. 以上 諸結果를 보아 處理한 것이 오히려 不利한 結果를 나타내니 Campbell Early에 對해서는 좀더 다른 方法이 硏究되지 않는 한 實用的 價値가 없다고 생각된다. A leading variety of grapes, Campbell Early, was treated with 100 ppm solution of Gibberllin. Treatments were conducted 8 days before and 10 days after flowering. Gibberllin treatment at this dosage hastened fruit ripening about 4 days, but cluster parts, including peduncle, pedicels and rachis were dried partly, and treated fruit yields were decreased at the rate of 50% of untreated plots. Seedless fruits were produced more at treated plots than the untreated ones, but undesirable results were obtained for fruit production of this leading variety, Campbell Early. For the practical uses, more useful concentrations or application methods should be studied on this Campbell Early grape.

銀杏나무에 있어서의 車枝에 關한 調査硏究 : 1. Relationship Between the Number of Main Branches on Trunk and Diameter and Area of Small-end and Large-end of the Trunk 第1報 主幹에서 伸出된 主枝數에 따른 上口直徑과 下口直徑 및 上口面積과 下口面積과의 關係

朴道秉 慶尙大學校 1980 論文集 Vol.19 No.1

車枝일때 主幹의 가늘어지는 狀況을 알고자 主幹 30cm 사이에서 伸出된 主枝數別로 直徑과 面積을 計測算出하였던 바 그 結果는 다음과 같다. 1. 下口直徑 平均値 104.57∼149.85㎜ 上口直徑 平均値 83.99∼129.06㎜ 下口面積 平均値 8588∼17636㎟ 上口面積 平均値 5540∼13081㎟ 2. 下口直徑 100에 對한 上口直徑區別 指數 主枝 0枝區 92.47 主枝 1枝區 88.80 主枝 2枝區 87.60 主枝 3枝區 85.91 主枝 4枝區 83.83 主枝 5枝區 82.89 主枝 6枝區 79.61 3. 同回歸方程式 Yd=91.6738-1.9346X 4. 下口面積 100에 對한 上口面積의 區別指數 主枝 0枝區 85.65 主枝 1枝區 79.27 主枝 2枝區 77.09 主枝 3枝區 74.13 主枝 4枝區 70.72 主枝 5枝區 68.89 主枝 6枝區 63.98 5. 同 回歸方程式 Ya=84.1283-3.2961X 6. 以上에 의하여 計數的으로 明瞭한 바와 같이 主幹의 同一 높이 또는 가까운 距離內에서 2枝 以上의 主枝를 伸出시킴은 主幹을 急激히 가늘게 하므로 좋지 않으며 主枝의 數가 많은 車枝일수록 더욱 좋지 않음을 알 수 있다. This experiment was carried out to investigate the effect of main branches on the slenderness of trunks of Ginkgo tree(Ginkgo biloba). Sixty trunks were randomly selected and cut with 30 cm in length, which retained 0 to 6 main branches. Diameters and areas of small-end large-end of the trunks were measured. The results are summarized as follows: 1. Diameters of large-end of the trunks ranged from 104.57 to 149.85mm, and those of small-end, from 83.99 to 129.06mm. Areas of large-end of the trunks ranged from 8588 to 17636㎟, and those of small-end, from 5540 to 13081㎟. 2. Ratios of diameter of small-end to those of large-end were calculated 92.47, 88.80, 87.60, 85.91, 83.83, 82.89, and 79.61mm for trunks with 0, 1, 2, 3, 4, 5 and 6 main branches respectively. 3. Regression equation for the decrease of diameter in accordance with the increase of main branches was estimated as Yd=91.6738-1.9346 X. 4. Ratios of area of small=end to those of large-end were estimated 85.65, 79.27, 77.09, 74.13, 70.72, 67.89, and 63.98 ㎟ for trunks with 0, 1, 2, 3, 4, 5 and 6 main branches respectively. 5. Regression equation for the decrease of area due to the increase of main branches was found as Ya=84.1283-3.2961 X 6. Conclusively, more than two main branches positioned from the near distance caused a significant decrease of both small-end diameter and area in a practical point of view.

Experiments were carried out to observe the effects on rooting by the treatment of basal cut surface. At the same time the differences of rooting between the new shoots and the shoots of past year were studied. 1. The Euonymus japonicus rooted 100% at any case in summer cutting. 2. As for total number of roots, there was no significant difference between horizontal cut surface and oblique cut surface, and there were greater differences in the case of new shoots than in the case of old shoots of past year. 3. As for total length of roots, there was no significant difference between horizontal cut surface, and oblique cut surface, and there were greater differences in the case of new shoots than in the case of old shoots of past year.

This study attempts to analysis the present situation of farm management and the related industriesin order to present the suitable industries for promoting the farmers' income in mountain area. This study is based on the survey data obtained from 30 sample mountain vellages in 10 Guns located in central, wetern and northen Kyeougnam Province, where lots of mountain vellages are scattered here and there. Major findings obtained from the analysis are summarized as follows: 1) Area of cultivated land in mountian villages was generally smaller than that in plain vellages. BUt major finding of thes tudy indicated that the standard of living in the study area depended upon not only the size of cultivated land but also the skills of management to understand exavtly the regional and togographical situaltion, to utilize the developmental resources effectively, and to diversify income sources. This means that upbringing of competent Saemaul leaders is very important for promoting the income of mountain villages. 2) Various crops were being planted in a samll scale inmountain area. And those crops except rice adn barley were planted for self-sufficiency. Therefore, it is desired to select and cultivate intensively the kinds of crops which are regionally adn topographically suitable for maximizing farm inceomes of subsistant farmers. 3) The survey found out that in mountain area the farming of extensive fruits like chestnuts, persimmons, etc. is more favorable than that of intensive fruits like apples, pears, etc. 4) Because of topographical inappropriateness and lack of fertile cultivates land in mountain area, mowt vegetables, except onions in a few regions, were growing in a small scales for self-sufficiency. And the future of the vegetable cultivationin mountain area is also gloomy. 5) Since various grasses are abundantly growing in the wild in mountain area, the mountain villages are suitable for raising the herbivorous animals. Therefore it is recommeded to encourage raising the herbivorous animals, especially cattle, as one of the major income sources in mountain area. 6) It is true that sericulture has greartly contributed to the economic growth in mountain area with aboundant land suitable for mulberry trees. Recenly sericulture has, however, been shrinking due to the barriers of silk exportation. Without the barriers of silk exportation, sericulture will still play an important role on providing one of the major sources tom mountain villages. 7) The miscellaneous trees in most forest around the mountain villages were growing planlessly. Those parts of the forest are needed to be renewed by planting the useful, endurable, and regionally and topographically suitable kinds of trees.
