Article Figures & Data
Figures
- Fig. 1.
Pruning treatments and the corresponding percentage of branch length removed. The number of branches and the approximate number of buds on each tree is also shown.
- Fig. 2.
Relationship between leafmew root ratio and new root weight. Correlation and regression based on the natural logarithmic transformation of gram dry weights.
