Growth and morphogenesis of plant tissues under in vitro conditions are largely influenced by the composition of the culture media. In this study, effects of different inorganic nutrients (ZnSO₄ and CuSO₄) on callus induction and plant regeneration of Eleusine coracana in vitro were examined. Primary callus induction without ZnSO₄ resulted in improved shoot formation upon transfer of calluses to normal regeneration medium. CuSO₄ increased to 5× the normal concentration in the media for primary seed callus induction and plant regeneration resulted in a 4-fold increase in number of regenerated shoots. For long-term callus cultures, 2× KNO₃ or 4× Fe-EDTA could replace the requirement for α-naphthaleneacetic acid in the regeneration medium, while 60 μM ZnSO₄ or 0.5 μM CuSO₄ was optimal for plant regeneration from callus cultures.
