We investigated how the pea (Pisum sativum cv. Harunoka) root, upon return to an Al-free condition, recovers from injury caused by exposure to Al. Elongation and re-elongation of the root during the recovery process from Al injury occurred only in the apical 5-mm region of the pea root. With the model system of the pea root for recovery from Al injury, images of the root characterized by zonal staining with Evans blue showed the existence of two regions in the root apex consisting of rupture and zonary stained regions. Ruptures enlarged by increase in their depth but without widening of the intervals among zonary stained regions in the roots treated with Al continuously. On the other hand, intervals of the zonary stained regions were widened due to re-elongation of the root and were narrow in the rupture region in the recovery root.
我们研究了豌豆（Pisum sativum cv. Harunoka）根在返回无铝环境后，如何从暴露于铝中造成的损伤中恢复。在从铝伤害中恢复的过程中，根的伸长和再伸长仅发生在豌豆根的顶端 5mm 区域。利用豌豆根从铝伤害中恢复的模型系统，用 Evans 蓝进行带状染色的根图像显示，根尖存在两个区域，包括破裂区和带状染色区。在用铝连续处理的根中，破裂区通过加深而扩大，但带状染色区之间的间隔没有变宽。另一方面，由于根的再伸长，带状染色区的间隔变宽，而在恢复根的破裂区则变窄。
