Rates of photosynthesis and respiration of Scots pine seedlings, grown in water culture under conditions of nitrogen deficiency and supplied with nitrogen in ammonium or nitrate form, were investigated. Besides, the rates of photosynthesis and respiration of the seedlings were measured, after changing the form of supplied nitrogen. A rapid and different response of nitrogen deficient seedlings was found independent on the form of supplied nitrogen. The investigations also showed a change in rates of photosynthesis and respiration of seedlings after changing the form of nitrogen
