以日本北海道北部不同光照条件下生长的25株白桦（桦）幼树为研究对象，研究了树龄、枝尖高度、枝长、枝角和枝尖光效对幼树一级枝条生长的影响。分支生长量为一级分支内当年长枝总生物量（TBG）、一级分支当前产生的长枝数（CSN）和一级分支内当年长枝平均生物量（MSG）。总的来说，TBG、CSN和MSG与枝条年龄呈负相关，与枝条的高度、长度、角度（从水平方向）和光效呈正相关。TBG、CSN和MSG与自变量之间的关系具有个体特异性。TBG、CSN和MSG对枝条尖端光利用率的依赖性受最大光功率的影响。
The growth of first-order branches was measured in 25 saplings of Betula platyphylla Sukatchev var. japonica Hara growing under various light conditions in northern Hokkaido, northern Japan, and the effect of age, tip height, length, and angle of branches and light availability at the branch tips on branch growth were examined. Branch growth was evaluated as the total biomass growth of current-year long shoots within a first-order branch (TBG), the number of long shoots currently produced by the first-order branch (CSN), and the mean biomass of current-year long shoots within the first-order branch (MSG). In general, TBG, CSN, and MSG were negatively dependent on branch age and positively dependent on height, length, angle (from the horizontal), and light availability of the branch. The relationships between each of TBG, CSN, and MSG and the independent variables were individual specific. The dependency of TBG, CSN, and MSG on the light availability at the branch tips was affected by the maximum light ava...
