The procedure to measure MOE (Modulus of Elasticity) of planting stock was examined. And breeding of selection by MOE was studied. The relationships between MOE and diameters at stem base and tree height of planting stock were investigated. The results are summarized as follows :(1) MOE could be calculated from the deflection caused by adding weight to planting stock supported by two points.(2) Planting stock of growth have smaller MOE than those of good growth.(3) But there are some planting stock of good growth have large MOE.(4) And the planting stock have larger MOE at first year have larger MOE at second and third year.(5) Accordingly it is possible to select and breed them by means MOE.

检查了测量苗木 MOE（弹性模量）的程序。并对MOE选育进行了研究。研究了 MOE 与立木茎基部直径和树高之间的关系。结果总结如下：（1）MOE可以由两点支撑的定植砧木增加重量引起的偏转计算出来。（2）生长良好的立木砧木MOE比生长良好的较小。（3）但也有一些生长良好的立木砧木MOE较大。（4）第一年MOE较大的立木砧木，第二年和第三年MOE较大。（5）因此可以通过MOE方法对其进行选育。
