Gibberellic-acid (GA3) treatment of azukibean epicotyls resulted in alterations of the direction of newly deposited microfibrils, on the cell walls. Cells having transverse microfibrils on the inner surface of the wall were observed more frequently in GA3-treated epicotyls than in untreated or water-treated ones. This effect of GA3 was negated by simultaneously supplied colchicine. A crossed polylamellate structure was observed in the inner portion of the walls of GA3-treated cells, but not in the inner portion of the walls of colchicine-treated cells. The wall formed under the influence of colchicine consisted of microfibrils running in the same direction.
赤霉素（GA3）处理菜豆下胚轴导致新沉积的微纤维在细胞壁上的方向发生改变。在 GA3 处理的下胚轴中，比未处理或用水处理的下胚轴中观察到更多的具有横向微纤维的细胞。同时供应秋水仙碱可以否定 GA3 的这种作用。在 GA3 处理细胞的壁的内层观察到交叉的多层层状结构，但在秋水仙碱处理细胞的壁的内层中没有观察到。在秋水仙碱的影响下形成的壁由沿同一方向延伸的微纤维组成。
