Use of X-ray microanalysis for study of cation distribution in potassium deficient pumpkin roots

Natalia Burmistrova, Marina Krasavina, Alexander Pogorelov

Abstract


Ice slices of root tissues were investigated by X-ray microanalysis. 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.

Keywords
