Increased sensitivity of the respiratory system of plants grown in Gibberellic acid toward fluoride

Journal Article:

Abstract

Gibberellic acid in concentrations between 2 and 80 mg/l does not affect the ratio of radioactivities of /sup 14/CO/sub 2/ liberated from glucose-6-/sup 14/C and -1-/sup 14/C(C/sub 6//C/sub 1/) when acting for several hours on sliced wheat leaves, and that at a concentration of 10 mg/l it does not alter the degree of inhibition of respiration due to fluoride, iodoacetate and malonate or the consumption of oxygen. A linear relationship was established between the decrease in /sup 14/CO/sub 2/ liberation from glucose-/sup 14/C and the concentration of gibberellic acid. The C/sub 6//C/sub 1/ ratio as well as the absolute values of radioactivity decrease more rapidly in the course of several days after the germination of plants grown in a solution of gibberellic acid (10-20 mg/l) than in the water-grown controls. Fluoride inhibits the respiration of plants grown in gibberellic acid more than of those grown in water, its tissue concentration being either equal or less in the gibberellic -grown plants; the effect of iodoacetate and malonate is the same with plants of equal age (4 days) in both variants. 11 references, 1 figure, 4 tables.
