영문 초록

To product grafts and construct its spread-system effectively, this study was carried out to investigate into effects on the survival percentage and growth in walnut trees (Juglans sinensis Dode) according to transplanting type and post-epicotyl grafting treatment. In the average survival percentage of the grafting according to post-epicotyl grafting transplanting type, TPGB1 (transplanting in grafting bed) showing 89.02% was highest. Also, the survival percentage was different from appropriate temperature and humidity within treatment. As a result of the average survival percentage of the grafting by species, KWN-3 having 81.59% was highest with high survival percentage of total treatment in general. In addition, it is concluded that the nutrition condition of scions and collecting parts are strongly related to survival percentage on having significantly difference of its survival percentage by species. The growth rate of the survival grafts by transplanting type after grafting revealed that all of the investigation items (height and diameter growth of grafts, diameter growth of scions and etc.) resulted in same trend. TPGB1 having the highest tree height growth, 15.97㎝ (2.0∼59.0㎝), showed the highest growth on diameter growth of shoots, 7.55㎜ (1.65∼14.71㎜), and scions, 8.12㎜ (1.82∼13.58㎜), as well. In the growth of each treatment according to different developing parts of shoots in grafts, the lateral bud, 12.05㎝, was much superior to the terminal bud, 9.57㎝, on only graft height growth. However, the survival rate according to collecting parts of scions and developing parts of shoots with same treatment was not different with among-species.
