This study was conducted to investigate the effect of grafting methods on plug seedling quality, growth after transplanting, and yield of oriental melon that those seedlings were raised in the 32 hole plug tray for protected cultivation. Number of leaf and leaf area in approach grafting were higher until 15 days after grafting but lower on 20 days after grafting. Plant height, stem diameter and content of chlorophyll were nearly the same of each grafting methods on 20 days after grafting. Growth of top part, that is, plant height, leaf number, and leaf area on root removed single cotyledon ordinary splice grafting was the highest among the grafting methods. In the underground part, dry weight of root was high and T/R ratio was the lowest. Seedling quality of root removed single cotyledon ordinary splice grafting was the highest among grafting methods before transplanting. Plant height, number of leaf, leaf area and dry weight of root removed single cotyledon ordinary splice grafting in the growth of field were the highest on 30 days after grafting among grafting methods and days required for first flowering was also shorter, 38.4 days among grafting methods. But Fruit weight, content of soluble solids, fruit hardness, and color characteristics in fruit quality were insignificant among each grafting methods. Consequently, grafting methods influenced on the seedling quality, of oriental melon early growth after transplanting and yields. It was concluded that root removed single cotyledon ordinary splice grafting was the best methods in present study. It will be needed to convert grafting methods. Thus new grafting method should be applied.

This study was designed to determine the effect of red LEDs during healing and acclimatization process on the survival rate and quality of grafted tomato seedlings. Red LEDs and no light (darkness) were used for treating three rootstock cultivars, which are 'B-Blocking', 'Kanbarune', 'High-power' in healing room. Results showed that survival rates of grafted seedlings in red LEDs were higher than those in no light treatment. Significant variation on survival rates of rootstock cultivars was observed in no light treatment but there was not significant variation in red LEDs treatment. Light treatment also reduced the percentage of infected plants, except for the 'Kanbarune' cultivar. Seedling quality in red LEDs was better than that in no light treatment by improving growth parameters such as plant height, leaf length, leaf width, leaf area, fresh and dry weight of shoot and root. Light treatments and rootstock cultivars did not affect number of leaves, leaf chlorophyll value and T/R ratio of seedlings, but seedlings in red LEDs were significantly more compact than those in no light treatment. Moreover, the root morphology of seedlings such as total root surface area, total root length, and number of toot tips in red LEDs was also greater than that in no light treatment.

Contents of mineral element and cytokinin in the xylem sap of 'Keumdongee' and 'Tongilhwang' oriental melons were compared with those in oriental melons grafted onto 8 rootstocks. The effect of grafting on the fruit quality of oriental melon was also investigated. Flesh firmness varied with rootstocks. Soluble solids contents in the placenta tissue of grafted 'Tongilhwang' were higher than that in the 'Keumdongee'. Electric conductivity of the xylem sap in own-rooted plants was higher in 'Keumdongee' than in 'Tongilhwang', but it increased in 'Tongilhwang' once they were grafted. The sap volume per plant was greater in 'Keumdongee' than in 'Tongilhwang'. The mineral concentrations varied considerably depending on the rootstock used. Xylem sap of grafted oriental melons contained a higher amount of mineral ions, especially $NO_3{^-}$ and $PO_4{^-}$, than did the sap in own-rooted plants. The increase in the mineral levels in sap due to grafting was most apparent in 'Tongilhwang'. Xylem sap from both 'Keumdongee' and 'Tongilhwang' contained trans-zeatin (t-Z), trans-zeatin riboside (t-ZR), and dihydrozeatin riboside (DHZR). Small amounts of isopentenyl adenine (IPA) and isopentenyl adenine riboside (IPAR) were also detected. Trans-zeatin riboside was the most abundant, followed by t-Z. Cytokinin concentration in 'Keumdongee' was not significantly influenced by rootstock type used, although the highest concentration of cytokinins in 'Keumdongee' was obtained with 'Chamtozwa' rootstock. However, the cytokinin concentration in 'Tongilhwang' increased with grafting irrespective of rootstock type used.

Almonds are one of the oldest sources of food and oil for man as used the ice cream, candy, roast, salting, chocolate, breads, backed, cookies, and flavoring ect. So, we wish to plant Almond in our country at the most parts of mountains. In this purpose we must be find out of both root stock of more compatibility and new techniques of grafting was rather simples as compared with the many steps of machinary involved today. This investigation has been carried out to reveral compatibility and practical controls of environment effectives involved in the occurence of each difference combination results in interspecific grafting of Almonds on the root stock of Prunus mandshurica and Prunus persica as materials during the 9 months period from March to November in 1978. With these selected scions were 4 varieties of Almond employing as the Hal1's hardy, Nonpareil, and Thompson grafted in the polyethylene green house with almost identical provision made for effective controls of automatical supplying to heating and mistsprayers as the $22{\sim}25^{\circ}C$ of temperature and 70~90% humidity. Following results have been obtained. Those environmental controls were more effective and practical to grafting unions and success by means veneer-grafting at the green house. 1. Hall's hardy Almond grafted on the root stock of Prunus persica was more compatibility than Prunus mandshurica. 2. The survival percentages as follows of the 95.33% of Hall's hardy/Prunus persica and 92.66% of Hall's hardy/Prunus mandshurica. And those were no significant between root stock of both species. 3. The 3 varieties of sweet Almond grafted on the root stock of P. mandshurica. And those were no significant between root stock of both species. 4. And the survival percentages as fellows. Thompson 92.66%, Nonpareil 90.66% and Kapareil 89.33% those grafted on the root stock of Prunus persica. 5. And then the survival percentage of interspecific grafts on the root Prunus mandshurica as follows of the materials of Thompson 89.66%, Nonpareil 87%, Kapareil 85%. 6. The analysis of variance were no significant among the interactions between 3 varieties Almond and 2 species of root stock plants. 7. And the growth of interspecific grafts of the high 161cm, diameter 12.3mm and length of roots 21.5cm growth as the Hall's hardy Almond grafted on the root stock of Prunus persica. 8. The root stock plants of Prunus mandshurica more effected to 6~8 days early developed leafing of scions and dark green colour than the Prunus persica. 9. The identical provision of automatic systems was more effective to graft unions and grafting process. 10. The veneer-grafting method at the green house was more effective and practical method for the mass production of Almond grafts.

This experiment was carried out to investigate the possiblity of harvest of the fruits of tomato and the tubers of potato by the graft cultivation in winter, simultaneously. One hundred percentage of the grafted explant between tomato and potato were survived. The yield of tuber was 2.178kg/10a in the grafted explant an d 687 kg/10a in potato. And the yield of fruits was 4,512kg/10a in grafted explant and 4,840 kg/10a in tomato and was decreased by 7% in grafted explant compared with common tomato, whereas brix of fruits was higer in the former than the latter.

접목을 실시할 때 접수와 대목의 적정한 생육은 접목을 용이하게 할 뿐만 아니라 활착 후 접목묘의 묘소질 지속에도 커다란 영향을 미칠 수 있다. 자연광 조건에서 육묘를 실시하면 묘의 생육이 불균일하여 묘소질이 일정치 않게 된다. 그러므로 인공광을 이용한 폐쇄된 환경 조건에서 육묘가 바람직하나, 대목용 박에 대한 적정 광합성 유효광량자속 또는 광주기가 제시되지 않고 있다. 본 연구의 목적은 대목용 박의 초기 생육에 미치는 광합성 유효광량자속과 광주기의 영향을 구명하는 데 있다. (중략)

배나무잎 이상반점증상의 이병여부를 조기에 판별할 수 있는 가장 간편한 검정방법을 개발코자 시험하였다. 접목시기는 늦어질수록 병징발현율이 감소하였다. 접목방법은 2중절접, 2중삭아절접 순으로 양호하였으나 숙련된 기술이 필요한 이중절접방법보다 간편한 2중삭아절접 방법이 대량검정에 적합하였다. 이상반점증상의 전염에 필요한 최소 접촉시간은 1일 이상이었고 칼루스가 형성되어 접목부위가 활착된 21일 이후에서 발병이 가장 높았다.

한국에서 웹툰의 인기는 과거에 비교해 볼 때 점차 확대 되고 있고, 한국 만화 시장에서 웹툰의 성장률은 이미 출판만화의 성장률을 뛰어 넘고 있다. 한국 웹툰을 주로 애용하는 이용층은 10대에서 20대가 주를 이루고 있었으나 점차 아동층의 이용증가세가 눈에 띄고 있다. 과거부터 한국에서 아동용 교육용으로서 애니메이션과 아동미술의 접목은 많이 시도되어 왔고 많은 성공을 거두고 있으며 마켓쉐어 또한 굉장히 높은 편이다. 이 두 가지를 이용, 웹툰과 아동미술의 접목 또한 아동들에게 영향력이 있을 것이라 예상 하고 이 두 분야의 접목에 대해 긍정적인 부분과 부정적인 부분을 비교분석하여 발전 방향을 제시하고자 한다.
