Abstract We grafted scions of Dahurian larch (Larix gmelinii var. japonica) onto Japanese larch (L. kaempferi) and F1 hybrid larch (L. gmelinii var. japonica × L. kaempferi) rootstocks and examined rootstock-scion compatibility by assessing the survival rate (SR) in two independent experiments. Scion overgrowth on the rootstock was not observed. SR was not significantly different among rootstocks due to large interquartile ranges (IQR) among clones within a rootstock type. Results suggested that the SR was more dependent on the clonal characteristics of the scion than on the growth vigor of the rootstock. Shoot elongation of grafts on F1 hybrid rootstock was superior to that of grafts on Japanese larch rootstock. Selection of an appropriate combination of scion and rootstock may improve the SR of grafted Dahurian larch and shorten the cultivation period.

嫁接落叶松 (Larix gmelinii var. japonica) 的存活率和枝条生长：日本落叶松 (L. kaempferi) 和 F1 杂交落叶松 (L. gmelinii var. japonica × L. kaempferi) 砧木的比较

摘要 我们将落叶松 (Larix gmelinii var. japonica) 的接穗嫁接到日本落叶松 (L. kaempferi) 和 F1 杂交落叶松 (L. gmelinii var. japonica × L. kaempferi) 砧木上，并通过评估存活率检查砧木 - 接穗的相容性(SR) 在两个独立的实验中。没有观察到砧木上的接穗过度生长。由于砧木类型内克隆之间的四分位距 (IQR) 较大，因此砧木之间的 SR 没有显着差异。结果表明，SR 更依赖于接穗的克隆特征而不是砧木的生长活力。F1 杂交砧木上的嫁接枝条伸长率优于日本落叶松砧木上的嫁接。
