Zusammenfassung: | 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[R] 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[R] contributes to solubilizing the Pb and Cd of the soil, in addition to contributing to a greater development of the crop. Key words: pollution, biostimulants, cations. La presente investigacion tuvo como proposito evaluar la influencia de la quitosana en plantas de girasol (Helianthus annuus L.), crecidas en suelos contaminados con altos niveles de iones metalicos y proponer una alternativa economica, simple y natural. Se evaluo la bioacumulacion de Plomo (Pb) y Cadmio (Cd) en las plantas cultivadas en un periodo de 60 dias, para ello, se realizaron tratamientos que incluian el suelo contaminado y la aplicacion foliar de Quitomax[R], a diferentes concentraciones. Al finalizar las evaluaciones se evidencio que la planta de girasol absorbe los metales pesados, confirmando que la aplicacion de Quitomax[R] contribuye a solubilizar el Pb y Cd del suelo, ademas de contribuir en un mayor desarrollo del cultivo. Palabras clave: contaminacion, bioestimulantes, cationes. |
