CARTAYA-RUBIO, Omar E.; MORENO-ZAMORA, Ana María  y  GURIDI-IZQUIERDO, Fernando. Influence of chitosan on sunflower (Helianthus annuus L.) plants grown with high levels of metal ions. cultrop [online]. 2023, vol.44, n.2  Epub 01-Jun-2023. ISSN 1819-4087.

The purpose of this research was to evaluate the influence of chitosan on sunflower plants (Helianthus annuus L.) in soils contaminated with high levels of metal ions and to propose an economic, simple and natural alternative. The bioaccumulation of Lead (Pb) and Cadmium (Cd) was evaluated in the cultivated plants in a period of 60 days, for this, treatments were carried out that included the contaminated medium and the foliar application of Quitomax® at different concentrations. At the end of the evaluations, it was evidenced that the sunflower plant absorbs heavy metals, confirming that the application of Quitomax® contributes to solubilizing the Pb and Cd of the soil, in addition to contributing to a greater development of the crop.
