CHANGE OF APPARENT WEIGHT OF PLANT TISSUES IN SOLUTION

III. THE EFFECT OF METHYLENE BLUE AND POTASSIUM CYANIDE ON PLASMOLYSED CELLS OF CARROT ROOT

Authors


Summary

If there is any active transport of water between plasrnolysed cells of carrot root and the plasmolyticum the respiratory regulators potassium cyanide and methylene blue have a negligible effect on it. With 0.5 M KNO3 and 0.7 M cane sugar the changes in the apparent weight in the presence of these regulators relative to that in their absence is probably due to effects on the change of solutes in the tissue.
