Water culture and sand culture seedlings of Scots pine were investigated in respect to their reaction to ammonium or nitrate source of nitrogen nutrition. Photosynthesis, respiration, and dry matter production were studied in three and four months old plants. The results are preliminary but they have indicated that the effect of various form of nitrogen nutrition on gas exchange and growth rates could change during the growing season.

he reaction of Scots pine (<i>Pinus silvestris</i> L.) seedlings to ammonium and nitrate form of nitrogen was investigated. Rates of photosynthesis and respiration, content of chlorophylls, and accumulation of organic substance were determined in 12 and 18 weeks old plants. The results have shown, that the forms of nitrogen does affect the amount of accumulated organic substance as well as its distribution in particular organs.
