“…For example, Lynn Miller and Toshio Murashige used a hormone balance in favor of auxin (i.e., 2 mg of 2iP and 3 mg of IAA) [22]. Other teams used a balance in favor of cytokinin [49,51,52,[56][57][58][59]. Later, other authors used new synthetic regulatory substances, again more inclined towards cytokinin, such as 1 mg of NAA and 2 mg of (2-chloro-4-pyridyl)-N -phenylurea (CPPU) or 2 mg of N-phenyl-N -1,2,3-thiadiazol-5-ylurea (TDZ) [56,59] (see Table 1).…”
