Elemental composition of Apium graveolens L. seeds as an indicator of the nutritional value of competitive organic products

Abstract

Abstract The elemental composition of Apium graveolens L seeds of root (Cupid and Root gribovsky) and leaf varieties (Samurai and Tender) was determined using x-ray fluorescence analysis. In quantitative terms, the macronutrients are dominated by Ca (1.59-2.24% dry matter) and K (0.8-1.28%), as well as Na, P, S, Mg, and microelements – iron, zinc and manganese. It is shown that there is a wide variability of indicators for macro-and microelements. Significant varietal differences in accumulation were noted for sodium, silicon, chlorine, strontium (variability of more than 70%), as well as aluminum, iron, titanium, nickel, copper, and bromine. Varieties Cupid is characterized by increased accumulation of iron, silicon, sulfur, potassium, titanium, zinc, zirconium; varieties Samurai – sodium, phosphorus, sulphur, chlorine, calcium; varieties Tender – potassium, manganese, copper, bromine, and barium; Root gribovskiy – manganese and bromine. A high level of variation in the elemental composition of celery seeds of root and leaf varieties makes it possible to select plants that differ in an increased content of deficient macro-and microelements.
