Abstract
The first appearance of mitotic figures in reactivatinig buds of 1-year-old ash seedlings is in leaf primordia. The occurrence of mitotic figures then progresses sequentially to the procambial cells and finally to the cambium at the base of the bud. Milotic reactivation of the cambium in progressively more proximal regions of the stem is slow, proceeding at a maximal rate of 6 centimeters per day.
摘要
在 1 年生榆树苗休眠芽的叶原基中首次出现有丝分裂现象。有丝分裂的发生顺序依次是导细胞，最后是芽基处的形成层。茎中近基端区域形成层的有丝分裂的重新激活较为缓慢，最大速度为每天 6 厘米。
