Effect of vanadium on lettuce growth, cationic nutrition, and yield
Lettuce plants (Lactuca sativa L.) cv. "grandes lagos" were cultivated in nutrient solutions containing = (control), 0.1. 0.2. 0.5 and 1 mg/kg of vanadium. Root and leaf growth (expressed as fresh and dry weights) was inhibited by doses 0.2 to 1 mg/kg V. Yields decreased with increasing rates of vanadium. Toxicity symptoms in the roots consisted of color darkenting, club shape of the main roots, reduction of secondary root number and length, and necrosis. Leaves from plants treated with 0.5 and 1.0 mg/kg V also showed turgidity loss. Vanadium accumulated in the roots and was poorly translocated to the leaves. All the treatments significantly increased vanadium root levels, but it augmented in the leaves.

Vanadium accumulated in the roots and was poorly translocated to the leaves. All the treatments significantly increased vanadium root levels, but it augmented in the leaves. |
