The ultimate success of the micropropagation protocol depends on the successful rooting
and survival of the plantlets in field conditions [15]. Many researchers emphasized that ex vitro
rooting has more advantage over in vitro rooting because ex vitro rooted plants have better root
system as compared to in vitro rooted plantlets [16]. In addition, the ex vitro technique
shortens the micropropagation cycle as the both rooting and acclimatization phases can be
done at the same time in a greenhouse [17]. Therefore, ex vitro rooting was attempted as a
means to develop a better root system as well as to decrease the micropropagation cost, labor,
and time from laboratory to field transfer [15, 18].
