| Research Abstract |
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.
