Cytokinin modulates auxin-induced rhizoid organogenesis.

<p>(A) Induction of rhizoids by 1.5 µg/ml 2, 4-D at various concentrations of kinetin. Scale bar, 2 mm. (B) Rate of rhizoid formation. (C) Number of rhizoids per explant. Asterisks in (B) and (C) indicate statistically significant differences (Student’s t-test; P<0.01) between the control and cytokinin-treated leaf explants; error bars show SDs.
