Plant growth hormones (i.e. auxin and cytokinin) are commonly used for tissue culture regeneration. A right
ratio between auxin and cytokinin can induce callus and organogenesis [10]. Shoot can be induced with high level of
cytokinin and low level of auxin [11, 12]. On the other hand, roots usually induce with high level of auxin [11,12].
These are caused by auxin capability to promote cell elongation and cytokinin is able to promote cell division [13].
