Abstract in another language
In the present study with Scots pine seedlings the interaction between nitrate/ammonium - and potassium nutrition was studied with the help of labelled nitrogen (15N). The major results are as follows:The seedlings absorb ammonium much more readily than nitrate.Optimum potassium supply leads to a higher protein content. This effect is to be attributed to an increased assimilation of nitrate and endogenous N-storage compounds.Potassium stimulated protein synthesis corresponds with a decrease of soluble N-containing compounds.Reduced potassium supply leads to the consequence that the additionally absorbed ammonium is incorporated in soluble N-containing compounds.The previously described alleviating effect of potassium on ammonium stress in coniferous seedlings is explained by the potassium mediated decrease of ammonium incorporation.-While uptake of nitrate is independent of potassium supply, ammonium uptake is reduced in the presence of potassium.
