The deficieny of inorganic phosphate in nutrient solution reduces by about 50 per cent NO<sub>3</sub>- absorption in corn seedlings, it decreases both <em>in vitro</em> and in vivo nitrate reductase (NR) activity, as well the potential and actual NR level and has a very weak effect on NR induction. Acid phosphatases activities increase in corn roots when the plants are grown in nutrient solution without phosphorus. We suggest that inorganic phosphate is required mainly for maintenance of NR activity rather, than for induction <em>in vivo</em> of nitrate reductase. It is not excluded that deficiency of inorganic phosphate in root tissue may be partly supplemented as the result of enhanced acid phosphatase activity.
