ボタンの苗生産に関する研究(1) : 接ぎ木における接ぎ穂の部位,結束材料,時期,品種および温度が活着に及ぼす影響

This study was undertaken to clarify the effect of bud position of scion, binding material, time, cultivar and temperature after grafting on graft-take of grafted tree peony.
The percentages of graft-take were not affected by bud positions or cultivars, and those in all plots were 100% or near 100%.
In grafting at the last 10 days of August, the percentages of graft-take in both polyuinyl tape plot and flax string one were near 100%.
In grafting from the last 10 days of August to the last 10 days of September, the percentages of graft-take were about 90% in all plots, regardless places eled in after grafting. In the first 10 days of November, the percentage of graft-take in thermostatic room plot was about 90%, but in the case of outdoor plot was under 50%.
In grafting carried out at the last 10 days of August and the middle 10 days of September the percentages of all plots were in range of 80% to 90%, regardless cultivars or places heeled in after grafting. However, the percentages of graft-take in grafting at the last 10 days of August and in heeling in thermostatic room tended to be equal or slightly high, as compared with those in grafting at the middle 10 days of September and in heeling at outdoor, respectivery.
