Light and hormones: interchangeability in the induction of nitrate reductase.
Suitable concentrations of kinetin and gibberellic acid permit induction of nitrate reductase in leaves of tobacco in the dark. Hormone sprays eliminate the need for light induction of the enzyme. The concentration of gibberellic acid required for optimal induction varies according to the concentration of kinetin supplied.
