Vanadium bioaccumulation in Pisum sativum seedlings
1993
Nowakowski, W. (Warsaw Agricultural Univ. (Poland). Faculty of Horticulture)
Vanadium bioaccumulation calculated as the ratio of its content in plant biomass to that in the substrate (Vbi-index) was studied in pea. Vbi was on average 11.275, 11.770 and 13.153 in the roots, and 0.809, 0.749 in the shoots of the cultivars Opal, Laser and Ramir, respectively. This indicates cultivar differences in vanadium uptake, and low translocation rates from roots to shoots. Vanadium (3 to 30 mg/l) decreased shoot and root fresh and dry masses of the three cultivars. Seedlings of the cv. Opal were the most susceptible to higher concentrations of vanadium (20 to 30 mg/l), whereas seedlings of cv. Laser were the most resistant
