Popis: | Environmental stresses are forcing breeders to produce new plant genotypes with higher resistance to stressors. Biochemical markers of stress tolerance would assist in the selection of tolerant cultivars on the early stages of plant development. The aim of these studies was to examine whether the concentration of micro and macroelements of embryos and/or endosperm could specify the wheat grains in terms of their tolerance to stress conditions. Two sensitive to drought (Radunia and Raweta), two tolerant (Nawra and Parabola) and one with intermediate tolerance (Manu) were chosen. After dividing embryos and endosperm, the microelements content (Mn, Fe, Cu, Zn and Mo) was analyzed by inductively coupled plasma mass spectrometry (ICP-MS) and macroelements (K, Ca, Mg, P and S) by inductively coupled plasma optical emission spectrometry (ICP-OES). Independent of genotype, the concentration of all elements was higher in embryos than in endosperm. In both embryos and endosperm of tolerant plants, higher content of microelements (except for Cu in embryos) was detected. The accumulation of macroelements was lower in embryos of tolerant plants (except for K), however, in the case of endosperm, higher amounts of these elements, were registered. In embryos of Manu genotype, the content of microelements was more alike to sensitive and macroelements to tolerant plants but in endosperm, the level of both micro- and macroelements was more similar to tolerant ones. It was concluded that mineral composition of wheat grains, especially those in embryos, could inform about possible resistance of genotypes to stress conditions. |
