Abstract: | The terminal, apical shoot meristem ofN. tabacum cv. Wisconsin 38 normally differentiates into a flower after producing 30 to 40 nodes. The influence of leaves and roots
on the regulation of flowering was evaluated by counting the number of nodes produced after removal of leaves or the induction
of adventitious roots. Leaf removal has no effect on the number of nodes produced before flower formation. Root induction
significantly increases the number of nodes produced before flower formation. The plant behaves as if it were measuring the
number of nodes between the meristem and the roots as a means of regulating meristem conversion from vegetative to floral
differentiation. |
