Goal. Estimation of the influence of mineral fertilization of Silybum marianum L. on the intensity of accumulation of heavy metals in its leaf mass and seeds. Methods. field, laboratory atomic absorption method, mathematical and statistical processing. Results. Intensive absorption and accumulation of leaf mass and seeds of Silybum marianum L. lead, cadmium and zinc in quantities far exceeding the maximum permissible levels were questioned the possibility of its useproducts in the medical needs of the population and requires measures to reduce their accumulation in plants. In particular, the least accumulated is lead, cadmium and zinc in the leaf mass and the seeds of Silybum marianum L. in the absence of any fertilization of its crops. When applying fertilizers, the least amount of lead accumulates by the plants of Silybum marianum L. when using a mixture of ammonium nitrate, simple phosphate and potassium chloride. The greatest accumulation of lead by seeds is observed when fertilizing Silybum marianum L. with ammonium nitrate, and leaf mass when fertilizing with potassium chloride. The least cadmium accumulates with the leaves of Silybum marianum L. for fertilization with superphosphate simple, and the seeds for fertilization with a mixture of fertilizers. Most absorb the leaf mass and seeds of Silybum marianum L. cadmium for fertilizing plants with ammonium nitrate. When fertilizer is applied, the least zinc accumulates in the seeds of the Silybum marianum L. when using a mixture of ammonium nitrate, simple phosphate and potassium chloride, and in the leaf mass using potassium chloride. The highest accumulation of zinc by the seeds and leaf mass of the Silybum marianum L. was observed for the fertilization of its crops with ammonium nitrate. |
