Because the vanadium (V) chemistry provides that a significant amount of V in soil water can exist as vanadate which has been shown to have inhibitory effects on plant some enzymes, we analyzed the concentration of V in soil water, and examined the effect of such concentrations of vanadate on plant growth and metabolism. Concentration of V in water of collected soil samples was 0.013 to 0.040 μM. Vanadate‐treatment experiments with rye or wheat showed that 0.1 uM vanadate had slight effects on seed germination, and growth (shoot and root), photosynthesis (leaf), respiration (leaf and root), and three typical types of membrane H+‐ATPases (leaf and root) of the plants and contents of cellular various components (leaf and root). These results, at least, suggest that even if all of the V in soil water exists in the form of vanadate, effects of the vanadate on growth and metabolisms of rye or wheat may be insignificant.
