“…Citrus plants irrigated with water with lithium compounds had necroses along leaf edges, interveinal leaf chlorosis, and leaf abscission (Bingham et al 1964). An elevated concentration of lithium in solution (50 mM LiCl) caused necrosis of tobacco leaves (Naranjo et al 2003). Hence, maize seems to be the plant revealing lithium toxicity symptoms at relatively high concentrations in solution, which implies potential toxicity if green parts of plants contaminated with lithium were used as the feedstuff. )…”

Irrigation of cultivated plants can be a source of toxic lithium to plants. The data on the effect of lithium uptake on plants are scant, that is why a research was undertaken with the aim to determine maize ability to bioaccumulate lithium. The research was carried out under hydroponic conditions. The experimental design comprised 10 concentrations in solution differing with lithium concentrations in the aqueous solution (ranging from 0.0 to 256.0 mg Li • dm -3 of the nutrient solution). The parameters based on which lithium bioretention by maize was determined were: the yield, lithium concentration in various plant parts, uptake and utilization of this element, tolerance index (TI) and translocation factor (TF), metal concentrations in the above-ground parts index (CI) and bioaccumulation factor (BAF). Depression in yielding of maize occurred only at the highest concentrations of lithium. Lithium concentration was the highest in the roots, lower in the stems and leaves, and the lowest in the infl orescences. The values of tolerance index and EC 50 indicated that roots were the most resistant organs to lithium toxicity. The values of translocation factor were indicative of intensive export of lithium from the roots mostly to the stems. The higher uptake of lithium by the above-ground parts than by the roots, which primarily results from the higher yield of these parts of the plants, supports the idea of using maize for lithium phytoremediation.

An effect of lithium (Li ? ) on growth, circumnutation, and glutamate-induced excitation in sunflower (Helianthus annuus L.) seedlings was investigated using time-lapse photography and extracellular electrical potential measurements. The seedlings were treated with a micro and millimolar concentration of lithium chloride (LiCl) both persistently in a hydroponic medium and acutely through Li ? injection. The length of hypocotyls, fresh weight of seedlings, intensity and period of circumnutation, and the number of action potentials (APs) after glutamate (Glu) injection were determined. It was found that the circumnutation intensity and period did not depend on hypocotyl length and fresh weight of seedlings. Under persistent Li ? treatment, the circumnutation intensity was constant at a concentration between 0.2 and 20 mM although the hypocotyls were significantly shorter in relation to the control, whereas at a concentration of 40 mM circumnutation intensity decreased without any changes in the hypocotyl length. Under persistent treatment with 0.5 and 20 mM Li ? , the period of circumnutation was significantly prolonged. The number of APs in a Glu-induced series significantly increased in the seedlings exhibiting an Li ? -induced decrease in circumnutation intensity (in 40 and 60 mM Li ? ). Additionally Li ? injection before Glu injection also augmented the series of APs in seedlings growing without Li ? in hydroponic medium. These Li ? -sensitive responses demonstrated that circumnutation and growth are partly independent processes and reveal a relationship between circumnutation intensity and excitability in Helianthus annuus seedlings.
