Patients who present with severe maxillary bone loss Secondary to trauma or resorption provide a unique diagnosis and difficulty in implant installation. To solve this problem, various bone grafting methods and graft materials can be used in these compromised cases. But for the patients required wide reconstruction, autogenous iliac bone has been used widely because of easy harvesting of much corticocancellous bone. Usually, implant installations are performed 6-12 months later after grafting. but this method necessary long treatment period and additional surgery. To avoid this disadvantages, bone grafting with immediate implant installations are frequently used. But special care is necessary to prevent postoperative complication in this method. We present three cases of veneer grafting with immediate implant installation. These patients had a knife-edge shaped alveolar bone due to labial alveolar bone loss. We reconstructed this alveolar bone with veneer grafting with iliac bone and performed immediate implant installation. There was no complications during healing periods in these three cases. Six months later, we found good survival of grafting bone and osseointegration of these implants, so we could perform prosthetic treatment successfully.

This study was carried out to find out the proper method of grafting of Magnolia grandiflora L. Magnolia kobus DC. was used as stocks and the modified veneer grafting method in which a flap was attached to the cut surface of scion was adopted. And also the environment of the grafting beds was controlled for giving optimum humidity (90-100%) and temperature ($20-25^{\circ}C$). The results are summarized as follows: 1. Two year-old seedlings of M. kobus were best as stocks for grafting of M. gantiflora. 2. The modified veneer grafting which brought the successful result of 43 to 89.5 percent found to be very efficient method. 3. The environmental control made of vinyl tunnel and screen (lath) was very effective to attain to the excellent result of 89 percent. 4. For scions, one to two year-old branches with well developed winter buds collected just before the time of grafting gave the best results. 5. The optimum season for grafting in Kwangju districts was 15 to 20, April.

Hovenia dulcis var. koreana Nakai, the oriental raisin tree, has been considered not only fruit but an herbal medicine in East Asia including Korea, Japan and east China. As honey plant, value of this species had been rising steadily. The aim of this study was conducted to develop the propagation technique by scion collection time, scion age and vinyl house on survival rate of H. dulcis. The survival rate by veneer grafting showed no significant differences among 3 new cultivars. The scion collection at the northern temperature zone was observed to be the most appropriate time before the spring equinox when the plants are fully dormant. Especially, the installation of vinyl house showed 86% survival rate by veneer grafting. The scion age was effective 1 year shoot than 2 years shoot for increase the grafting survival rate. In this case, the installation of vinyl house can contribute above 80%.

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.

In the present study an experiment on the interspecific grafting of European and American filberst on the root stock of Korean filbert (C. heteropylla & C. sieboldiana) by means of veneer graftings in the green house was carried out and those survival percentage and growth was also investigated. The obtained results can be summarized as follows. 1. Interspecific grafting of European and American filberts on root stock of Korean filbert (C. heterophylla & C. sieboldiana) was 97%~98.3% of survival. 2. Those Interspecific grafts was higher compatibilities and nonsukering of root stocks of Korean filberts in the 1~2 years old. 3. Those mean growth of interspecific grafts was 106.7cm~111cm of height and 11.7mm~14.6mm of diameters at the stem base.

1. In the comparison of survival ratio among three different methods(bark graft, veneer graft, root graft), bark graft showed the highest survival ratio and root graft was the lowest. It was shown to be significant at the level of 5% in the analysis of variance for the results. It was able to be supposed that one of the main causes for the results was the different amounts of ferric tannic acid which was formated owing to the reaction of grafting knife with tannic acid oozing from cutting faces of the tree. In juvenile tissue graft, the survival ratio of inverted radicle graft was a little higher than that of juvenile stem graft, but there was no significant difference between two methods in analysis of variance. 2. The most hairs of chestnut tree leaves were recognized as stellates on the most part of leaves except for venation. The number of rays in the stellates was ranged from 4 to 8 generally. It was shown to be highly significant differences at the level of 1% among the each race growing at the similar environmental condition in the length of ray and the distributed ratio of the stellates having different ray number. 3. Excepting for the basal width of serration there were no significant differences between $Imakita_1$, $Imakita_2$ as well as between $Teteuchi_1$, $Teteuchi_2$ at the each point of experimental items in this study. Such results made this study more useful. 4. Among the races that were growing in the similar environmental condition, there were highly significant differences at the level of 1% in the length and the width of serration. 5. The rolling of hair, the angle of serration from the leaf margin, the existence of lateral vein in the serration, the intrusion of main vein into the serration and the width of main vein were observed to be somewhat useful as the subsidiary methods for the identification of chestnut races.
