In other side, the minimum numbers of formed roots per
shoot were appeared with NC (3) followed by N7 (9.7), N5 (11)
and N2 (12.3) media with significant differences between them.
Present results were in agreement with those reported by Ma
and Gang [18] who demonstrated that, the best root growth
was observed with B5 medium supplemented with 2 mg/l Kin
and 1 mg/l of IAA. Moreover, Hedayat et al. [12] concluded
that, all regenerated shoots of Tanacetum cinerariifolium developed
roots on B5 medium containing 2 mg/l NAA.
