The Effect of Nitrogen and Chlormequat on the Translocation of Ca, Mg and K

In a pot experiment using Avena sativa L. the effect of increasing doses of nitrogen and the application of chlormequat (CCC) on the translocation of Ca, Mg and K was investigated. Changes in the content of these elements were monitored in the panicles, stems, upper green leaves and lower yellowing leaves. The application of CCC significantly manifested in increased content of Ca and Mg only in the lower yellowing leaves. This increase was not observed for K. Increasing the nitrogen doses led to an insignificant increase in the content of Ca and Mg in the leaves and K in the stems.
