호도나무 대목촉성재 (臺木促成材) Plastic 원통을 이용한 유경녹기 (幼莖綠技) 접목에 관한 연구
윤기식(Ki Sik Youn),구관효(Gwan Hyo Goo),조정석(Chung Suk Jo) 한국산림과학회 1989 한국산림과학회지 Vol.78 No.2
This study was carried out to produce the grafts of Juglans sinensis by juvenile grafting method which epicotyl of newly germinated seeds were used as stocks and juvenile fresh shoots were used as scion. The results obtained were as follows ; 1. When plastic tube installed covering up seed with soil up to 6㎝ height for diameter increment of epicotyl, the epicotyl can be grown up to thickness of 10㎜. 2. When the soft fruit branches and the soft water sprout with the terminal bud 8㎝ to 12㎝ long were used as scions, the survival rates showed 90 Percent. 3. The optimum date for making juvenile grafts was around the 20th of May, and the survival rates of grafted seedlings showed 86 percent in average. 4. The grafted seedlings showed first sprouting the 15th of June, that is 25 days after making graft, and the sprouting rate was 72 percent. 5. The height-growth of grafted seedlings finished at the end of July, and diameter growth lasted into the end of October,

Present studies were carried out to understand the way of propagation of Osmanthus which has much value as ornamental trees in southern parts of Korea. The results of these experiments were summarized as follows: 1. In order to increase the survival of Osmanthus, scions of Osmanthus was grafted on the stocks of Ligustrum obtusifolium S. et Z. The survival of the grafts were 63% for Osmanthus fragrans var. aurantiacus Makino and 60% for Osmanthus asiaticus Nakai. 2. The growth of the grafts was initiated from 28th day after the grafting and the height growth resumed three times, and the growth percentage was 63% for Osmanthus fragrans var. aurantiacus and 59% for Osmanthus asiaticus. 3. Cutting medium mixed with perlite and vermiculite (1:1) gave better results than either use of them separately, and the rooting percentage was 93% for Osmanthus fragrans var, aurantiactts and 90% for Osmanthus asiaticus. 4. Rooting percentage of cuttings was lower in hard-wood cutting than that of in green-wood cutting. 5. Grafts showed fairly good height growth in July and September, and ceased growth in October. 6. Correlation between height growth and diameter of root collar of grafts in case of Osmanthus fiagrans var. aurantiacus was highly significant and showed linear correlation (r=0.70^(**))
