A model of phytohormone distributions during the formation of root primordia. The critical periods of adventitious root induction were 1 day (a), 4 days (b), and 5 days (c). a At 1 day of induction, all four types of phytohormones were mainly distributed in S&Cs. b As the cambium thickened, the phytohormones were transferred to the cambium cells. GA3 and ZR were also present in ray cells. c When the meristem cells began to rapidly divide, the four types of phytohormones were mainly distributed in meristems. In addition, the GA3 and ZR levels rose further in ray cells. S&Cs sieve and companion cells, green color = IAA, yellow color = ABA, red color = GA3, blue color = ZR
