Calculated stress patterns in lateral branches place the locations of maximum flexural stresses at the same places as the maximum concentrations of growth hormones. The gradients of stress and hormone concentration also have similarity.In branch epinasty and negative geotropism of branches, the directions of the stress vectors correlate with the imbalance of auxin in the upper and lower portions of the branches.
计算得出的侧枝的应力模式使最大弯曲应力的位置与生长激素的最大浓度位置一致。应力和激素浓度的梯度也具有相似性。在枝条的反转和枝条的负向向地性中,应力矢量的方向与枝条上下部分生长素的不平衡有关。
