Abstract
The quantitative content of 22 chemical elements (As, Br, Co, Cr, Cu, Mn, Mo, Nb, Ni, Pb, Rb, Sc, Se, Sr, Ti, Zn, Zr, V, Y, Ca, Fe, K) in the vegetative organs of Hemerocallis hybrida was determined for the first time with the help of X-ray fluorescence analysis with synchrotron radiation (XRD). Comparative data on the elemental composition of leaves and rhizomes in the plants of varieties Speak to me and Regal Air in the forest-steppe zone of West Siberia are presented. The specific features of the content of 19 microelements and 3 macroelements in above-ground and underground organs were revealed. The concentrations of all elements in the leaves and rhizomes of Speak to me and Regal Air plants were at the maximum permissible level. The leaves of Regal Air were distinguished by the higher (by a factor of 1.5-7) content of molybdenum, bromine, chromium, rubidium, selenium. The concentrations of lead, strontium, yttrium, zirconium, niobium were 1.5-6 times higher in the leaves of Speak to me. Underground organs were found to be the richest in trace elements. It was shown that the total content of trace elements is 1.5-3 times higher in the organs of the Regal Air variety. The variety specificity of the quantitative content of chemical elements in vegetative organs is detected.
