EFFECT OF CANE SUGAR ON THE UPTAKE OF CHLORIDE BY DISCS FROM CARROT ROOT

Authors


Summary

The exosmosis and reabsorption of electrolytes by freshly cut discs is retarded by the presence of 0.2 M and 0.02 M cane sugar. The presence of cane sugar during pre-treatment of freshly cut discs depresses the uptake of chloride when they are transferred to 0.01 M KCl; the presence during the uptake by discs pretreated in water causes an increase in the uptake of chloride; these effects are probably additive when the sugar is present during pre-treatment and uptake.
