Changes in the endogenous hormone content and ratios of various types of embryogenic cultures were clearly diverse: higher contents of abscisic acid (ABA) and indole-3-acetic acid (IAA) occurred in the SPC explant (single-piece cotyledonary somatic embryo) with a regenerated single bud (SB type). In a MW-type somatic embryo (milky-white single-piece-cotyledon explant), the gibberellic acid (GA₃)/ABA ratio was the highest (1.807), and the IAA/GA₃ ratio was the lowest (0.902).
