Highly significant data regarding the effect of different
concentrations of IAA (Control, 0.1, 0.3 and 0.5 mg/l) on
the regeneration of chrysanthemum plantlets clearly depicted
that an intermediate level of IAA (0.3 mg/l) showed
its superiority amongst all the other IAA levels, in all the
parameters studied (Table 1). Maximum shoot initiation
percentage (80), shoots per plant (4.0), length of shoot
(5.1 cm), leaves (11.3) and nodes per shoot (5.6) were
recorded in 0.3 mg/l IAA
