reduce the adverse impact of drought by conserving water and carbon energy, such that plants can use limited water to survive drought for an extended period of time ( Kang, 2002 ). Plant growth regulators such as trinexapac-ethyl (TE) are traditionally

growth regulators are another factor affecting in vitro generation. BA, the most commonly used cytokinin, has been shown to stimulate adventitious shoot induction in a broad range of plant species ( Burns et al., 2012 ; Ghimire et al., 2012 ; Shaik et
