Potassium, sodium and Chloride in the protoplasm of characeae

元データ 日本植物生理学会

概要

Using vacuolar perfusion, which enabled us to replace the cell sap with a solution containing no K^+, Na^+ and Cl^-, the concentrations of these ions in the protoplasm of three species of fresh water Characeae were determined. They were respectively, 78, 2 and 27 mM in Nitella flexilis, 101, 9 and 31 mM in Nitella pulchella, and 112, 3 and 21 mM in Chara australis. Our previously reported results (3) indicating that the chloroplast layer contained much more Na^+ and Cl^- than the endoplasm has been questioned in the light of the present results.
