Description
Tomato plants were grown by hydroponics with a nutrient solution containing 0, 6, 12 meq/L sodium chloride or sulfate. Although the salts had virtually no effect on fresh fruit yields and on the dry weights of various plant organs, a few changes were observed in the chemical compositions of fruit, lamina, and petiole. The potassium ion in fruit, as well as the sodium and chloride ions, increased in concentration with the addition of sodium chloride. The addition of sodium chloride also resulted in decreases in potassium and nitrate concentrations, together with increases in sodium and chloride concentrations, in such vegetative organs as lamina and petiole. The addition of sodium sulfate had virtually no effect on potassium concentration in fruit, although it caused increases in sodium and sulfur concentrations in plant. These results suggest that an increase in chloride concentration in plant accelerates the transport of the potassium ion from vegetative organs to fruit. A decrease in potassium concentration in vegetative organs was compensated by an increase in sodium concentration. The chloride ion seems to inhibit selectively and competitively the uptake of the nitrate ion in root, whereas the sulfate ion non-specifically inhibits the uptake of the inorganic anions in root.
