Abstract

Abstract

Excised roots of selected crop plants were exposed to 10 µg/ml of lead nitrate in the presence of 2,4-dinitrophenol or sodium azide at 10−4 and 10−5 molar concentration. Additionally, roots were exposed to lead nitrate at pH 4.5, 5.5, and 7.0, and at temperatures of 4 and 24C. Lead uptake was not influenced by metabolic inhibitors or low temperature, but was dependent on solution pH, suggesting that the process does not require energy expenditure by the plant.
