The effects of the branch size influece upon cone-production was stndied in 3-year old, 2-year old, and 1-year old branches of five Kuromatsu trees bearing much cones.
Results are as follows : 1 . The cones are produced more often in large branches than in small ones. 2 . The branches bearing cones in two sucessive years are larger than other branches. 3 . The branches bearing cones in two successive years are seen in the upper part of the crown of the vigorous trees. 4 . Comparing the total volume of all 1-year old branches originated from a 2-year old branch, the volume is larger in a 2-year old branch with cones than in one without cones. 5 . It is desirable to make a tree develop many large branches to increase cone-production. |
