Vanadium Uptake by Plants

The kinetics of vanadium absorption by excised barley (Hordeum vulgare L., cv. Eire) roots were investigated with respect to ionic species of V in solution, time and concentration dependence, Ca sensitivity, and interaction with various anions, cations, and pH levels. The role of metabolism in V absorption was also studied using anaerobic treatment (N(2) gas) and chemical inhibitors (NaN(3), KCN, or 2,4-dinitrophenol). Approximately one-third of...
