A comparative regeneration of three types of explants prepared from axillary meristems, plumular apices and hypocotyls of chickpea (Cicer arietinum) was carried out using four thidiazuron (TDZ) treatment methods. The first and third ones included the short-term 20 μM TDZ pre-treatment for all three explant types followed by non-supplementation or supplementation of TDZ (4 μM) into the shoot induction medium (SIM), while the second and fourth ones lacked TDZ pre-treatment followed by non-addition or addition of 4 μM TDZ in the SIM. Axillary meristem explants produced the best results with seed pre-treatment using 20 μM TDZ without TDZ in SIM and showed the highest rate of regeneration efficiency (71.33 ± 1.5%) after 20 days. Concurrently, plumular apex explants from TDZ-primed seeds was ranked second, exhibiting a regeneration percentage of 54.33 ± 2.3% in SIM without supplementation of TDZ, whereas explants from hypocotyls generated from seeds subjected to any of the TDZ treatments were not regenerated on any SIMs after 20 days. © 2021.
