| 摘 要： | 由来自日本落叶松原产地日本长野县、群马县2个种源和30年代由日本引进的辽宁在河县种源进行的造林试验表明，3个种源树高、胸径、冠幅差异不显，但庄河种势略好；从小枝性状上看，庄河种源的小枝长度、个数、枝重、叶重方面均优于日本的2个种源；在抗性方面，庄河种源具有良好的适应性和抗逆性。由此说明，次生种源更能适应本地区的生态气候条件，其后代在数量性状和抗性上占有优势。

| Abstract: | Plantations by two provances from Japan were compared with plantation by introduce seeds in 30s from Japan in Zhuanghe County.The height,DBH,crown width shows little difference,the length,number and weight of branch and leaves were higher in acclimatized local plantation.Also,local trees have higher stress tolerance.The result revealed that local provance was more suitable to climates in the region and young tree have many advantage in numeric property. |
