In Azukia stem cuttings, root primordia always appeared in the interfascicular regions between the endodermis and the interfascicular cambium. Transverse cell divisions were observed as the first events in the process of root formation. They began to occur 10 hr after cuttings had been made and were restricted to the interfascicular regions about 1 mm above the basal cut end of the cutting. In each of interfascicular region, 10 to 20 cells divided. Transverse divisions were followed by longitudinal divisions, which began to occur 18 hr after cuttings had been made. The early process of root primordium formation is distinguished by the following three phases: the first phase during which no cell division occurs (0-8 hr), the second phase during which transverse cell divisions occur (8-16 hr) and the third phase during which longitudinal divisions occur (16-24 hr). Cuttings in each phase responded differently to test substances.
