It is shown that the cytoplasm of the meristematic and differentiated cells of potassium dificiest roots maintains a high potassium level. The vacuoles of various root cells loose more K and accumulate more Na and Mg than does the cytoplasm. %K potassium deficiency %K K %K Na %K Mg distribution %K X-ray microanalysis %U http://pbsociety.org.pl/journals/index.php/asbp/article/view/1212
