Vanadium for Plants: Photosynthesis Rate
Vanadium (V)
For the plant – the rate of photosynthesis.
In the plant organism vanadium is part of porphyrins and hemoproteins.
A positive role of vanadium in the fixation of atmospheric nitrogen by microorganisms, in lipid metabolism, and in photosynthesis has been established.

Plants absorb vanadium from the soil. The vanadium content in plants averages 0.1 mg% (by weight).
Vanadium deficiency significantly reduces chlorophyll content, halving the rate of photosynthesis (under high light intensity). The rate of photosynthesis, calculated per unit of chlorophyll, decreases by half under high light intensity in the case of vanadium deficiency, while under low light conditions, the addition of vanadium does not significantly affect the rate of photosynthesis.
The hyperaccumulator of vanadium is the toxic mushroom death cap Amanita phalloides (Fr.) Link. (Amanitaceae).
The mold Aspergillus niger Tiegh. (Trichocomaceae) (an industrial producer of several enzymes) develops normally only in the presence of vanadium salts.

Medicinal plants containing vanadium:
• species of rosehip Rosa L., Rosaceae (fruits, content – 3 mg%);
• sessile alternanthera Alternanthera sessilis (L.) DC, Amaranthaceae (herb).

A lot of vanadium is found in cacti, parsley greens, dill, carrots, soybeans, cereals, and mushrooms.
